10 = 1 s / 1000 = 1 s
Acceleration time 1.
0.000 ... 1800.000 s
20.000 s / real32
Defines deceleration time 1 as the time required for
the speed to change from the speed defined by
parameter
(not from 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.
