Code Description
PID-28 PID FF-Gain
Sets the ratio that adds the target to the PID output. Adjusting this value
leads to a faster response.
PID-29
PID Out LPF
Used when the PID controller output changes too quickly or the entire
system is unstable, due to severe oscillation. In general, a lower value (default
value=0) is used to speed up response time, but in some cases a higher value
increases stability. The higher the value, the more stable the PID controller
output is, but the slower the response time.
PID-30 PID Limit Hi,
PID-31 PID Limit Lo
Limit the output of the controller.
PID-35
PID Out Mode
Selects one of the PID output modes to modify the PID output. Modifications
can be made by adding input values and the main operation frequency of
the PID output to the final PID output value.
The following table lists the 5 modes that are available.

1 PID+Main Freq
2 PID+EPID1 Out
3 PID+EPID1+Main
4 PID or Main
PID-36
PID Out Inv When PID-36 (PID Out Inv) is set to ‘Yes,’ the difference (error) between the
reference and the feedback is set as the feedback–reference value.
PID-37 PID Out Scale Adjusts the volume of the controller output.
PID-40–46 Step Ref
1–7
Sets the PID reference by multi-function input settings at IN 65–71.
D-50
PID Unit Sel
Sets the unit for the control variable.
0: CUST is a custom unit defined by the user.
