Selected motor, dynamic braking is still pending.
The firing angle is forced to 150° and single firing pulses to
suppress the DC current are given, thus the drive cannot be
started or re-started while dynamic braking is active, except if
21.01 Start mode = Flying start dynamic braking.
Check:
− The setting of 20.43 Dynamic braking acknowledge source.
− The setting of 21.01 Start mode.
