ENGLISH

 Frequency Reference and Acceleration/ Deceleration Times

 Frequency Reference Setup(b1-01)

Set parameter b1-01 according to the frequency reference used.

 Acceleration/ Deceleration Times and S-Curves

There are four sets of acceleration and deceleration times which can be set in the

C1- parameters. The default activated accel/ decel times are C1-01/02. Adjust

these times to the appropriate values required by the application. If necessary S-

curves can be activated in the C2- parameters for softer accel/ decel start and

end.

 Test Run

Perform the following steps to start up the machine after all parameter settings have

been done.

1. Run the motor without load and check if all input, outputs and the sequence

work as desired.

2. Connect the load to the motor.

3. Run the motor with load and make sure that there is no vibrations, hunting or

motor stalling occurs.

After taking the steps listed above, the drive should be ready to run the application

and perform the basic functions. For special setups like PID control etc. refer to the

instruction manual.

b1-01 Reference source Frequency reference input

0 Operator keypad

Set the frequency references in the d1- parameters and used digital

inputs to switch over between different reference values.

1 Analog input Apply the frequency reference signal to terminal A1 or A2.

2 Serial Comm. Serial Communications using the RS422/485 port

3 Option Board Communications option card

4 Pulse input Set the frequency reference at terminal RP using a pulse train signal.
