Keep the drive in a clean environment by installing the drive in an enclosure panel or selecting an installation area free of airborne dust lint and oil mist be sure to leave the required space between drives to provide for cooling and take proper measures so the ambient temperature remains within allowable limits and keep flammable materials away from the drive yaskawa offers protective designs for drives that must be used in areas subjected to oil mist and excessive vibration contact yaskawa or your yaskawa agent for details 19

Refer to installing a magnetic contactor at the power supply side on page 30 19

Refer to mechanical installation on page 3 19

Repetitive starting stopping 19

Select a mccb molded case circuit breaker or rcd rcm with a rated current that is 1 to 2 times higher than the rated current of the drive in order to avoid nuisance trips caused by harmonics in the drive input current also refer to installing a molded case circuit breaker mccb on page 306 19

Selecting a molded case circuit breaker or rcd rcm devices 19

Settings 19

Where an rcd residual current device or rcm residual current monitor at the drive power supply side is used for protection in case of direct or indirect contact only an rcd or rcm of type b according to iec 60755 is allowed 19

Yaskawa recommends lowering the carrier frequency particularly when audible noise is not a concern it is beneficial to reduce the load increase the acceleration and deceleration times or switch to a larger drive to help keep peak current levels under 150 be sure to check the peak current levels when starting and stopping repeatedly during the initial test run and make adjustments accordingly 19

Temperature derating 319

The drive standard ratings are valid for an installation altitude up to 1000 m if the altitude exceeds 1000 m both the drive rated voltage and the rated output current must be derated for 1 per 100 m the maximum altitude is 3000 m 319

To ensure the maximum performance life the drives output current must be derated when the drive is installed in areas with high ambient temperature in order to ensure reliable drive overload protection the parameters l8 12 and l8 35 must also be set according to the installation conditions 319

A timer should be set 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 376

C communications timing 376

Command messages from master to drive 376

Common_ tmonly 376

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 376

Response messages from drive to master 376

The master must wait for a specified time between receiving a response and re sending 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 the table below 376

To prevent 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 376

C message format 377

Common_ tmonly 377

Function code 377

Message content 377

Slave address 377

After eight shift operations perform an xor operation with the result and the next data in the message function code register address data continue with steps 3 to 5 until the last data has been processed 378

An initial value of ffffh i e all 16 bits equal 1 must be used for crc 16 calculations in the memobus modbus protocol 378

C message format 378

Calculate the crc 16 checksum using the following steps 378

Command data 378

Error check 378

Perform a crc 16 calculation on the response message data as described above as a validation check the result should match the crc 16 checksum received within the response message 378

Perform an xor operation of this value and the slave address 378

Repeat steps 3 and 4 until eight shift operations have been performed 378

Response data 378

Right shift the result 378

Table c crc 16 checksum calculation example 378

The drive uses a crc 16 cyclic redundancy check checksum method for checking data validity use the procedure described below when calculating the crc 16 checksum for command data or when verifying response data 378

The example in table c shows the crc 16 calculation of the slave address 02h and the function code 03h yielding the result 40d1h 378

The result of the last shift or xor operation is the checksum 378

The starting value is ffffh 378

When the drive receives data it calculates the crc 16 checksum from the data and compares it to the crc 16 value received within the message both must match before a command is processed 378

When the overflow bit of the shift operation becomes 1 perform an xor operation of the result from step 3 above and the fix value a001h 378

Below are some examples of command and response messages 379

C message examples 379

Function code 08h performs a loopback test this test returns a response message with exactly the same content as the command message and can be used to check communications between the master and slave user defined test code and data values can be set 379

Loopback test 379

The following table shows a message example when performing a loopback test with the slave 1 drive 379

The following table shows message examples when reading status signals error details data link status and speed references from the slave 2 drive 379

Using the function code 03h read a maximum of 16 memobus modbus registers can be read out at a time 379

C message examples 380

Function code 10h allows the user to write multiple drive memobus modbus registers with one message this process works similar to reading registers in that the address of the first register to be written and the data quantity are set in the command message the data to be written must be consecutive so that the register addresses are in order starting from the specified address in the command message the data order must be high byte then lower byte 380

If an error message occurs when sending the torque compensation value a set h5 07 rts 1 0 380

If parameter values are changed using the write command an enter command may be necessary to activate or save the data depending on the setting of h5 11 refer to h5 11 communications enter function selection on page 374 and refer to enter command on page 391 for detailed descriptions 380

The drive supports two types of enter commands as shown in the table below an enter command is enabled by writing 0 to register numbers 0900h or 0910h these registers can only be written to attempting to read from these registers will cause an error 391

When changing parameters via memobus modbus h5 11 determines whether an enter command is necessary to activate parameter changes in the drive 391

When writing parameters to the drive from the plc using memobus modbus communication parameter h5 11 determines whether an enter command must be issued to enable these parameters this section describes the types and functions of the enter commands 391

A list of memobus modbus errors appears below 392

C 1 communication errors 392

In the following situations the slave drive will ignore the command message sent from the master and not send a response message 392

Memobus modbus error codes 392

Note if the slave address specified in the command message is 00h all slaves execute the write function but do not return response messages to the master 392

Slave not responding 392

When a communications error overrun framing parity or crc 16 is detected in the command message when the slave address in the command message and the slave address in the drive do not match remember to set the slave address for the drive using h5 01 when the gap between two blocks 8 bit of a message exceeds 24 bits when the command message data length is invalid 392
