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 99).

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 99).

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.
