Parameters
3-51 Ramp 2 Ramp Up Time
Range: Function:
Size [0.05 - If asynchronous motor is selected, enter
related 3600 s] 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.
3-52 Ramp 2 Ramp Down Time
Range: Function:
Size [0.05 - Enter deceleration time from
related 3600 s] 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.
3.4.5 3-8* Other Ramps
3-80 Jog Ramp Time
Range: Function:
Size [0.05 Enter the jog ramp time, which is the
related - 3600 acceleration/deceleration time between 0 Hz
*
s] 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.

Function:
[0.05 - Enter the quick stop ramp time from the
3600 s] 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.
