Parameters 205
Defines deceleration time 1 as the time required for the
speed to change from the speed defined by parameter
) 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
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.
