Ramp-Up Time For Pid Setpoint; Ramp-Down Time For Pid Setpoint; Co: Pid Setpoint After Pid-Rfg - Siemens MICROMASTER 440 Parameter Manual

Parameter Description
P2257

Ramp-up time for PID setpoint

CStat: CUT
P-Group: TECH
Sets the ramp-up time for the PID setpoint.
PID Setpoint (%)

Dependency:
P2200 = 1 (PID control is enabled) disables normal ramp-up time (P1120).
PID ramp time effective only on PID setpoint and only active
- when PID setpoint is changed or
- when RUN command is given.
Notice:
Setting the ramp-up time too short may cause the inverter to trip, on overcurrent for example.
P2258

Ramp-down time for PID setpoint

CStat: CUT
P-Group: TECH
Sets ramp-down time for PID setpoint.

Dependency:
- P2200 = 1 (PID control is enabled) disables normal ramp-up time (P1120).
- PID setpoint ramp effective only on PID setpoint changes.
- P1121 (ramp-down time) and P1135 (OFF3 ramp-down time) define the ramp times used after OFF1
and OFF3 respectively.
Notice:
Setting the ramp-down time too short can cause the inverter to trip on overvoltage (F0002) / overcurrent
(F0001).
r2260

CO: PID setpoint after PID-RFG

P-Group: TECH
Displays total active PID setpoint after PID-RFG in [%].
Note:
r2260 = 100 % corresponds to 4000 hex
