ƒ The acceleration and deceleration times refer to an output frequency change from
0 Hz to the max. output frequency set in C0011.

Note!
If the acceleration and deceleration times are set too short, and under
unfavourable operating conditions, the controller can be switched off with
TRIP OC5. In these cases, the acceleration and deceleration times must be set
so that the drive can follow the speed profile without Imax reaching a drive
system.
