 Note!
If the acceleration and deceleration times are set too short, and
under unfavourable operating conditions, the controller can be
switched off with TRIP OC1 or OC3. In these cases, the
acceleration and deceleration times must be set so that the drive
can follow the speed profile without I

reaching a drive
system.
