P1027 – PID Setpoint Backup via Keypad (P1025)
Adjustable
Range:
0 = Off
1 = On Factory
Setting:
1
Properties:
Access groups
via HMI:
SPLC
Description:
This parameter sets whether the backup function of the PID setpoint via keypad is active or inactive.
If P1027 = 0 (Inactive), the inverter will not save the value of the PID setpoint when disabled. Therefore, when
the inverter is enabled again, the PID setpoint value is 0.0 %.
P1028 – PID Output N=0
Adjustable
Range:
0.0 to 100.0 %
Factory
Setting:
0.0 %
Properties:
Access groups
via HMI:
SPLC
Description:
The P1028 parameter works together with the P0218 parameter (Condition to Leave the Zero Speed Disable),
providing additional requirement for leaving the condition. Thus, it is necessary that the error of the PID (the
difference between the setpoint and process variable) is greater than the value programmed in P1028 for the
inverter to operate the motor again, this state is known as “wake up”.
P1031 – X Process Variable Value
P1032 – Y Process Variable Value
Adjustable
Range:
0.0 to 100.0 % Factory
Setting:
P1031=90.0 %
P1032=10.0 %
Properties:
Access groups
via HMI:
SPLC
Description:
These parameters are used at the digital outputs functions for signaling/alarm, and will show:
Process Variable > VPx (Function 1 of the Application) and
Process Variable < VPy (Function 2 of the Application).
