) Note!
If the acceleration and deceleration times are set too short the
controller may switch off with TRIP OC5 under unfavorable
service conditions. In these cases, the acceleration and
deceleration times should be set short enough so that the drive
can follow the speed profile without reaching I
max
of the controller.
