Parameters 173
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
to zero). Emergency stop mode and activation
source are selected by parameters
and
respectively.
Emergency stop can also be activated through fieldbus.
Note:
• Emergency stop Off1 uses the standard deceleration
ramp as defined by parameters
…
.
• The same parameter value is also used in frequency
control mode (ramp parameters
3.000 s
0.000 …1800.000 s
Emergency stop Off3 deceleration time.
10 = 1 s
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 (
) are equal, speed reference (
) is a straight line.
This function is only active in remote control.
Off
Variable slope disabled.
0
On
Variable slope enabled (not available in local control).
1
Defines the rate of the speed reference change when
variable slope is enabled by parameter
For the best result, enter the reference update interval into
this parameter.
50 ms
2…30000 ms
Variable slope rate.
1 = 1 ms
No.
