P1132 Ramp-down initial rounding time Min: 0.00
CStat: CUT Datatype: Float Unit: s Def: 0.00
P-Group: SETPOINT Active: first confirm QuickComm. No Max: 40.00
Defines rounding time at start of ramp-down as shown in P1130 (ramp-up initial rounding time).
Note:
Rounding times are recommended, since they prevent an abrupt response, thus avoiding detrimental effects
on the mechanics.
Notice:
Rounding times are not recommended when analog inputs are used, since they would result in
overshoot/undershoot in the inverter response.
P1133 Ramp-down final rounding time Min: 0.00
CStat: CUT Datatype: Float Unit: s Def: 0.00
P-Group: SETPOINT Active: first confirm QuickComm. No Max: 40.00
Defines rounding time at end of ramp-down as shown in P1130 (ramp-up initial rounding time).
Note:
Rounding times are recommended, since they prevent an abrupt response, thus avoiding detrimental effects
on the mechanics.
Notice:
Rounding times are not recommended when analog inputs are used, since they would result in
overshoot/undershoot in the inverter response.
P1134 Rounding type Min: 0
CStat: CUT Datatype: U16 Unit: - Def: 0
P-Group: SETPOINT Active: Immediately QuickComm. No Max: 1
Defines smoothing response to OFF1 command or setpoint reduction.
If parameter P1134 = 0 it aviods sudden changes in setpoint frequency. Moreover, it gives smoother torque
(no jerk).

Possible Settings:

Dependency:
No effect until total rounding time (P1130) > 0 s.
Notice:
P1134 = 0:
Rounding acts at all times. At a sudden reduction of the input value, overshoot can occur.
P1134 = 1:
Rounding does not act upon sudden reduction of input value during acceleration process.
Rounding times are not recommended when analog inputs are used. They would result in
overshoot/undershoot in the inverter response.
