The acceleration time is the time corresponding to the linear frequency rise from 0Hz to the set
maximum frequency (P105). If an actual setpoint of <100% is being used, the acceleration time is
reduced linearly according to the setpoint set.
The acceleration time can be extended by certain circumstances, e.g. FI overload, setpoint lag,
smoothing, or if the current limit is reached.
NOTE:
Care must be taken that the parameter values are realistic. A setting of P102 = 0 is not
permissible for drive units!
Information on ramp gradient:
Ultimately, the moment of inertia of the rotor determines the possible ramp gradient.
If the ramp is too steep, the motor may "break down".
Extremely steep ramps (e.g.: 0 - 50Hz in < 0.1 s) should generally be avoided, as these may
cause damage to the frequency inverter.

{ 5.00 } above size 8
The braking time is the time corresponding to the linear frequency reduction from the set
maximum frequency (P105) to 0Hz (P105). If an actual setpoint <100% is being used, the
deceleration time reduces accordingly.
The braking time can be extended by certain circumstances, e.g. by the selected >Switch-off
mode< (P108) or >Ramp smoothing< (P106).
NOTE:
Care must be taken that the parameter values are realistic. A setting of P103 = 0 is not
permissible for drive units!
For information about ramp gradients: please refer to parameter (P102)
