- Acceleration and deceleration times are affected by the amount of torque generated by the motor the load torque and the inertia moment set a longer accel decel time when stall prevention is enabled the accel decel times are lengthened for as long as the stall prevention function is in operation install one of the available braking options or increase the capacity of the drive for faster acceleration and deceleration
- Yaskawa recommends using ring terminals on all drive models drive models 2a0069 to 2a0415 and 4a0058 to 4a0675 require the use of use ring terminals for ul cul compliance use only the tools recommended by the terminal manufacturer for crimping
- Yaskawa recommends installing a ground fault circuit interrupter gfci to the power supply side the gfci should be designed for use with ac drives e g type b according to iec 60755 select a molded case circuit breaker mccb or gfci with a rated current 1 to 2 times higher than the drive rated current to avoid nuisance trips caused by harmonics in the drive input current refer to installing a molded case circuit breaker mccb or ground fault circuit interrupter gfci on page 366 for more information
- The cooling fan of a standard motor should sufficiently cool the motor at the rated speed as the self cooling capability of such a motor reduces with the speed applying full torque at low speed will possibly damage the motor reduce the load torque as the motor slows to prevent motor damage from overheat figure i shows the allowable load characteristics for a yaskawa standard motor use a motor designed specifically for operation with a drive when 100 continuous torque is needed at low speeds

- Frequently applying overexcitation deceleration raises the motor temperature because regenerative energy is mainly dissipated as heat in the motor in cases where frequent application is required make sure the motor temperature does not exceed the maximum allowable value or consider using a braking resistor option in lieu of overexcitation deceleration during overexcitation deceleration 2 hunting prevention in v f control is disabled do not use overexcitation deceleration in combination with a braking resistor option
- When the motor reaches a relatively low speed at the end of hsb the output frequency is kept at the minimum output frequency set to e1 09 for the time set to n3 03 increase this time if the inertia is very high and the motor coasts after hsb is complete
- Use parameters n3 13 through n3 23 to adjust overexcitation deceleration when repetitive or long overexcitation deceleration causes motor overheat lower the overexcitation gain n3 13 and reduce the overslip suppression current level n3 21 during overexcitation deceleration 1 l3 04 4 the drive decelerates at the active deceleration time c1 02 and c1 04 set this time so no overvoltage ov fault occurs
- The set deceleration time is ignored during hsb use overexcitation deceleration 1 l3 04 4 or a dynamic braking option to stop the motor within a specified time braking time varies based on the load inertia and motor characteristics enabling hsb and keb ride thru simultaneously will trigger an ope03 error hsb must be triggered by a digital input set to h1 oo 68 after the hsb command is given the drive will not restart until the motor is completely stopped and the run command is cycled use parameters n3 01 through n3 04 to adjust hsb

- If the motor current exceeds the value set to n3 21 during overexcitation deceleration due to flux saturation the drive automatically reduces the overexcitation gain parameter n3 21 is set as a percentage of the drive rated current set this parameter to a relatively low value to optimize deceleration if overcurrent ol1 or ol2 occur during overexcitation deceleration reduce the high slip suppression current level
- Enables high frequency injection while overexcitation deceleration is executed injecting high frequency into the motor increases loss and shortens deceleration time this function tends to increase audible noise from the motor and may not be desirable in environments where motor noise is a concern
- During overexcitation deceleration 2 l3 04 5 the drive decelerates using the active deceleration time while adjusting the deceleration rate to keep the dc bus voltage at the level set to l3 17 the actual stopping time will be longer or shorter than the set deceleration time depending on the motor characteristics and the load inertia increase the deceleration time if overvoltage occurs ov entering a run command during overexcitation deceleration cancels overexcitation operation and the drive reaccelerates to the specified speed
- The optimum setting for n3 13 depends on the motor flux saturation characteristics gradually increase the gain to 1 5 to 1 0 to improve the braking power of overexcitation deceleration lower n3 13 when flux saturation characteristics cause overcurrent a high setting sometimes causes overcurrent oc motor overload ol1 or drive overload ol2 lowering n3 21 can also help remedy these problems

- Wiring the option
- When installing option cards to models 2a0004 to 2a0040 4a0002 to 4a0023 and 5a0003 to 5a0011 it may be necessary to route the cables connected to the option through the top cover to the outside models 2a0056 to 2a0415 4a0031 to 4a1200 and 5a0017 to 5a0242 have enough space to keep all wiring inside the unit
- Route the option wiring
- Replacing the drive covers and digital operator
- Replace and secure the front covers of the drive a d and replace the digital operator b
- Option installation
- Depending on the drive model some drives may require routing the wiring through the side of the front cover to the outside to provide adequate space for the wiring in these cases using diagonal cutting pliers cut out the perforated openings on the left side of the drive front cover sharp edges along the cut out should be smoothed down with a file or sand paper to prevent any damage to the wires

- Installing other types of braking resistors
- Installing a braking unit cdbr type
- If using a braking resistor option a sequence such as the one shown in figure 8 5 should be set up to interrupt the power supply in case the braking resistor overheats
- Figure 8 5 power supply interrupt for overheat protection example
- Figure 8 4 connecting a braking resistor unit lkeb type models 2a0004 to 2a0138 4a0002 to 4a0072 and 5a0003 to 5a0052
- Braking resistor overload protection
- Yaskawa siep yaip1u 01a ac drive p1000 technical manual
- When installing braking resistors other than the erf or lkeb types make sure that the drive internal braking transistor will not be overloaded with the required duty cycle and the selected resistance value use a resistor that is equipped with a thermal overload relay contact and utilize this contact to switch off the drive in case of braking resistor overheat
- To install a cdbr type braking unit connect the 3 terminal of the drive to the positive terminal on the braking unit next wire together the negative terminals on the drive and braking unit terminal 2 is not used connect the braking resistor to cdbr terminals 0 and 0 wire the thermal overload relay contact of the cdbr and the braking resistor in series and connect this signal to a drive digital input use this input to trigger a fault in the drive in case a cdbr or braking resistor overload occurs set l8 55 to 0 to disable dynamic braking transistor protection
- When multiple braking units are used they must be installed with a master slave configuration with a single braking unit acting as the master figure 8 7 illustrates how to wire braking units in parallel wire the thermal overload contact relays of all cdbrs and all braking resistors in series then connect this signal to a drive digital input this input can be used to trigger a fault in the drive in case of overload in any of the cdbrs or braking resistors
- Using braking units in parallel
- Installing peripheral devices
- Shut off the drive with an mc when a fault occurs in any external equipment such as braking resistors
- Installing peripheral devices
- Installing a molded case circuit breaker mccb or ground fault circuit interrupter gfci
- Installing a magnetic contactor at the power supply side
- Install an mccb or gfci for line protection between the power supply and the main circuit power supply input terminals r l1 s l2 and t l3 this protects the main circuit and devices wired to the main circuit while also providing overload protection
- Install a magnetic contactor mc to the drive input for the purposes explained below
- Drive outputs generate high frequency leakage current as a result of high speed switching install a gfci on the input side of the drive to switch off potentially harmful leakage current factors in determining leakage current size of the ac drive ac drive carrier frequency motor cable type and length emi rfi filter if the gfci trips spuriously consider changing these items or use a gfci with a higher trip level
- Disconnecting the power supply
- Consider the following when selecting and installing an mccb or gfci the capacity of the mccb or gfci should be 1 to 2 times the rated output current of the drive use an mccb or gfci to keep the drive from faulting out instead of using overheat protection 150 for one minute at the rated output current if several drives are connected to one mccb or gfci that is shared with other equipment use a sequence that shuts the power off when errors are output by using magnetic contactor mc as shown in figure 8 8

- Set a timer in the master to check how long it takes for the slave drive s to respond to the master if no response is received within a certain amount of time the master should try resending the message
- Response messages from drive to master
- If the drive receives a command from the master it will process the data received and wait for the time set in h5 06 until it responds increase h5 06 if the drive response causes overrun in the master
- Command messages from master to drive
- C communications timing
- To prevent a communications overrun in the slave drive the master should wait a certain time between sending messages to the same drive in the same way the slave drive must wait before sending response messages to prevent an overrun in the master this section explains the message timing
- The master must wait for a specified time between receiving a response and resending the same type of command to the same slave drive to prevent overrun and data loss the minimum wait time depends on the command as shown in table c
- Slave address
- Message content
- Function code
- Error check
- C message format
- The example in table c shows the crc 16 calculation of the slave address 02h and the function code 03h yielding the result d140h

- D ul and csa standards
- When connecting the drive to more than one motor for simultaneous operation disable the electronic overload protection l1 01 0 and wire each motor with its own motor thermal overload relay enable motor overload protection l1 01 0 when connecting the drive to a single motor unless another motor overload preventing device is installed the drive electronic thermal overload function causes an ol1 fault which shuts off the output of the drive and prevents additional overheating of the motor the motor temperature is continually calculated while the drive is powered up
- The drive has an electronic overload protection function ol1 based on time output current and output frequency that protects the motor from overheating the electronic thermal overload function is ul recognized so it does not require an external thermal relay for single motor operation this parameter selects the motor overload curve used according to the type of motor applied
- Setting range 0 to 5 min factory default 1 min parameter l1 02 determines how long the motor is allowed to operate before the ol1 fault occurs when the drive is running at 60 hz and at 150 of the full load amp rating e2 01 of the motor adjusting the value of l1 02 can shift the set of ol1 curves up the y axis of the diagram below but will not change the shape of the curves
- When using an external heatsink ul compliance requires covering exposed capacitors in the main circuit to prevent injury to surrounding personnel the portion of the external heatsink that projects out can be protected with the enclosure or with the appropriate capacitor cover after completing drive installation use table d 1 to match drive models with available capacitor covers order capacitor covers from a yaskawa representative or directly from the yaskawa sales department refer to figure d for a detailed description of the capacitor cover parts
