172 Parameters
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.
3.000 s
0.000 …1800.000 s Acceleration time 1. 10 = 1 s
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.
