0.000 s / real32Defines the shape of the deceleration ramp at the end of
the deceleration. See parameter 23.16 Shape time acc 1.

60.000 s / real32Defines the acceleration time for the jogging function i.e.
the time required for the speed to change from zero to the
speed value defined by parameter 46.1 Speed scaling.
See section Jogging (page 61).
Acc time jogging23.20
10 = 1 s / 1000 = 1 sAcceleration time for jogging.0.000 ... 1800.000 s
60.000 s / real32Defines the deceleration time for the jogging function i.e.
the time required for the speed to change from the speed
value defined by parameter 46.1 Speed scaling to zero.
See section Jogging (page 61).

3.000 s / real32In speed control mode, this parameter defines the
deceleration rate for emergency stop Off3 as the time it
would take for the speed to decrease from the value of
parameter 46.1 Speed scaling. This also applies to torque
control because the drive switches to speed control on
receiving an emergency stop Off3 command.
In frequency control mode, this parameter specifies the
time it would take for the frequency to decrease from the
value of 46.2 Frequency scaling to zero.
The emergency stop mode and activation source are
selected by parameters 21.4 Emergency stop mode and
21.5 Emergency stop source respectively. Emergency stop
can also be activated through fieldbus.
Note: Emergency stop Off1 uses the standard deceleration
ramp as defined by parameters 23.11…23.19 (speed and
torque control) or 28.71…28.75 (frequency control).

Inactive / uint32Selects a source that forces the speed reference to zero
just before it enters the ramp function.
0 = Force speed reference to zero before the ramp function
