[0.05 -
3600 s]
If asynchronous motor is selected, enter
acceleration time from 0 Hz to
parameter 1-23 Motor Frequency. If PM
motor is selected, enter acceleration time
from 0 RPM to parameter 1-25 Motor
Nominal Speed. Select a ramp-up time such
that the output current does not exceed
the current limit in parameter 4-18 Current
Limit during ramping up.

Enter deceleration time from
parameter 1-25 Motor Nominal Speed to
0 RPM. Select a ramp-down time such
that the output current does not exceed
the current limit in
parameter 4-18 Current Limit during
ramping down.

3-80 Jog Ramp Time
Range: Function:

[0.05
- 3600
s]
Enter the jog ramp time, which is the
acceleration/deceleration time between 0 Hz
to parameter 1-23 Motor Frequency. Ensure
that the resulting output current required for
the given jog ramp time does not exceed the
current limit in parameter 4-18 Current Limit.
The jog ramp time starts after 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 s]
Enter the quick stop ramp time from the
parameter 1-23 Motor Frequency to 0 Hz.
During ramping, no overvoltage may occur
in the inverter, nor may the generated
current exceed the limit in
parameter 4-18 Current Limit. Quick stop is
activated with a signal on a selected digital
input or via the serial communication port.
