2 Parameters
2.2 List of parameters
Note: For U/f control and sensorless vector control (see p1300), a ramp-down time of 0 s does not make sense. The setting
should be based on the startup times (r0345) of the motor.
p1122[0...n] BI: Bypass ramp-function generator / Bypass RFG
VECTOR_G Can be changed: U, T
Data type: Unsigned32 / Binary
P-Group: Setpoints
Not for motor type: -
Min
-
Description: Sets the signal source for bypassing the ramp generator (ramp-up and ramp-down times = 0).
Notice: The parameter may be protected as a result of p0922 or p2079 and cannot be changed.
The bypass is kept for OFF1/OFF3.
Note: For VECTOR in encoderless operation, it is not permissible that the ramp-function generator is bypassed.
p1130[0...n] Ramp-function generator initial rounding-off time / RFG t_start_round
VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: Setpoints
Not for motor type: -
Min
0.000 [s]
Description: Sets the initial rounding-off time for the extended ramp generator. The value applies to ramp-up and ramp-down.
Note: Rounding-off times avoid an abrupt response and prevent damage to the mechanical system.
p1131[0...n] Ramp-function generator final rounding-off time / RFG t_end_delay
VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: Setpoints
Not for motor type: -
Min
0.000 [s]
Description: Sets the final rounding-off time for the extended ramp generator.
The value applies to ramp-up and ramp-down.
Note: Rounding-off times avoid an abrupt response and prevent damage to the mechanical system.
p1134[0...n] Ramp-function generator rounding-off type / RFG round-off type
VECTOR_G Can be changed: U, T
Data type: Integer16
P-Group: Setpoints
Not for motor type: -
Min
0
Description: Sets the smoothed response to the OFF1 command or the reduced setpoint for the extended ramp-function
generator.
Value: 0:
1:
Dependency: No effect up to initial rounding-off time (p1130) > 0 s.
Note: p1134 = 0 (continuous smoothing)
If the setpoint is reduced while ramping-up, initially a final rounding-off is carried out and then the ramp-up
completed. During the final rounding-off, the output of the ramp-function generator continues to go in the direction of
the previous setpoint (overshoot). After the final rounding-off has been completed, the output goes toward the new
setpoint.
