[0.05 -
3600.0 s]
Enter the deceleration time from 0Hz
the 1-23 Motor Frequency to 0Hz.
Choose a ramp-up time such that the
output current does not exceed the
current limit in 4-18 Current Limit
during ramping. See ramp-up time in

[0.05 -
3600.0 s]
Enter the jog ramp time, i.e. the
acceleration/deceleration time between
0Hz to 1-23 Motor Frequency. Ensure that
the resultant output current required for
the given jog ramp time does not exceed
the current limit in 4-18 Current Limit. The
jog ramp time starts upon activation of a
jog signal via the control panel, a selected
digital input, or the serial communication
port.
3-81 Quick Stop Ramp Time
Range: Function:
Size
related*
[0.05 -
3600.0 s]
Enter the quick stop ramp time from the
1-23 Motor Frequency to 0Hz. During
ramping, no over-voltage may arise in
the inverter, nor may the generated
current exceed the limit in 4-18 Current
Limit is activated by means of a signal on
a selected digital input or via the serial
communication port.
