Description
Defines deceleration time 1 as the time required for the speed
to change from the speed defined by parameter
scaling (not from parameter
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.

Defines the acceleration time for the jogging function ie. the
time required for the speed to change from zero to the speed
value defined by parameter
See section Rush control
Acceleration time for jogging.
Defines the deceleration time for the jogging function ie. the
time required for the speed to change from the speed value
defined by parameter 46.01 Speed scaling
See section Rush control
Deceleration time for jogging.
Defines the time inside which the drive is stopped if an
emergency stop Off3 is activated (ie. the time required for the
speed to change from the speed value defined by parameter

Emergency stop mode and activation source are selected by
parameters 21.04 Emergency stop mode

also be activated through fieldbus.
Note:
• Emergency stop Off1 uses the standard deceleration ramp
as defined by parameters 23.11...23.15.
• The same parameter value is also used in frequency
control mode (ramp parameters 28.71...28.75).
