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-
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 Techni-
cal Manual.
Set the frequency references in the d1-
switch over between different reference values.
Apply the frequency reference signal to terminal A1 or A2.
