Parameters 227
23.12 Acceleration time 1 Defines acceleration time 1 as the time required for the speed
to change from zero to the speed defined by parameter 46.01
Speed scaling (not to parameter 30.12 Maximum speed).
If the speed reference increases faster than the set
acceleration rate, the motor speed will follow the acceleration
rate.
If the speed reference increases slower than the set
acceleration rate, the motor speed will follow the reference.
If the acceleration time is set too short, the drive will
automatically prolong the acceleration in order not to exceed
the drive torque limits.

0.000…1800.000 s Acceleration time 1. 10 = 1
23.13 Deceleration time 1 Defines deceleration time 1 as the time required for the speed
to change from the speed defined by parameter 46.01 Speed
scaling (not from parameter 30.12 Maximum speed) to zero.
If the speed reference decreases slower than the set
deceleration rate, the motor speed will follow the reference.
If the reference changes faster than the set deceleration rate,
the motor speed will follow the deceleration rate.
If the deceleration rate is set too short, the drive will
automatically prolong the deceleration in order not to exceed
drive torque limits (or not to exceed a safe DC link voltage). If
there is any doubt about the deceleration time being too
short, ensure that DC overvoltage control is on (parameter
30.30 Overvoltage control).
Note: If a short deceleration time is needed for a high inertia
application, the drive should be equipped with braking
equipment such as a brake chopper and brake resistor.
