How to Program
3-41 Ramp 1 Ramp-up Time
Range:
0.01 - 3600.00 s
*
ExpressionLimits
Function:
The ramp-up time is the acceleration time from 0
RPM to the rated motor speed nM,N (par. 1-23),
provided that the output current does not reach
thetorquelimit(setinpar. 4-16). Thevalue0.00
corresponds to 0.01 s in speed mode.
3-42 Ramp 1 Ramp-down Time
Range:
0.01 - 3600.00 s
*
ExpressionLimits
Function:
The ramp-down time is the deceleration time from
the rated motor speed n
M,N
(par. 1-23) to 0 RPM,
provided that th ere is no over-voltage in the inverter
due to regenerative operation of the motor, or if the
generated current reaches the torque limit (set in
par. 4-1 7). The value 0.00 correspond s to 0.01 s in
speed mode. See ramp-up time in par. 3-41
