Parameters 173
23.23 Emergency stop time 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 46.01 Speed scaling or 46.02 Frequency
scaling to zero). Emergency stop mode and activation
source are selected by parameters 21.04 Emergency stop
mode and 21.05 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…23.15.
• The same parameter value is also used in frequency
control mode (ramp parameters 28.71…28.75).

0.000 …1800.000 s Emergency stop Off3 deceleration time. 10 = 1 s
23.28 Variable slope enable Activates the variable slope function, which controls the
slope of the speed ramp during a speed reference
change. This allows for a constantly variable ramp rate to
be generated, instead of just the standard two ramps
normally available.
If the update interval of the signal from an external control
system and the variable slope rate (23.32 Variable slope
rate) are equal, speed reference (23.02 Speed ref ramp
output) is a straight line.
This function is only active in remote control.
Off
Off Variable slope disabled. 0
On Variable slope enabled (not available in local control). 1
23.29 Variable slope rate Defines the rate of the speed reference change when
variable slope is enabled by parameter 23.28 Variable
slope enable.
For the best result, enter the reference update interval into
this parameter.
