Dependency:
Setting 1 automatically disables normal ramp times set in P1120 and P1121 and the normal frequency setpoints.
Following an OFF1 or OFF3 command, however, the inverter frequency will ramp down to zero using the ramp time set in P1121 (P1135 for OFF3).
Note:
The PID setpoint source is selected using P2253. The PID setpoint and the PID feedback signal are interpreted as [%] values (not [Hz]). The output of the PID controller is displayed as [%] and then normalized into [Hz] through P2000 (reference frequency) when PID is enabled.
In level 3, the PID controller source enable can also come from the digital inputs in settings 722.0 to 722.5 for DIN1 to DIN6 or from any other BiCo source.
The minimum and maximum motor frequencies (P1080 and P1082) as well as the skip frequencies (P1091 to P1094) remain active on the inverter output. However, enabling skip frequencies with PID control can produce instabilities.
