Example 4) Restart and mains supply restored
The drive controls a deceleration with the ramp set in Powerloss decel time.
The drive automatically controls the DC link voltage and prevents the Overvoltage alarm.
If the mains supply is restored and the Mains voltage OK signal is applied, the drive immediately stops the decel-
eration ramp and executes the acceleration ramp set in Powerloss accel time to pass to the set reference.
