When set TRUE, the following procedure is applied each time the motor is switched on and before closing the speed loop, based on
the external speed setpoint.
The drive must be used in speed loop mode.
When the drive is switched ON, the system is placed in open loop control.
Step 1:
For a time equal to the 'PMAC SVC Start Time' parameter, the current is ramped to the PMAC SVC Start Cur value. The sign is
dependent upon the speed loop setpoint. A normal value is between 0.5 to 1s.
Step 2:
Once Step 1 is complete, the position is ramped in such a way as to follow the speed setpoint generated, based on the configuration
(ramp, etc...), until the PMAC SVC Start Speed value is reached. The speed loop is then closed.
The ramp value must be kept low to ensure the motor follows the speed setpoint.
