In order to eliminate the offset occurring in Proportional (P) control, the manipulated output value is
manually corrected.
When the Manual reset is set to the plus (+) side:
The manipulated output value under the stable condition increases by the Manual reset value.
When the Manual reset is set to the minus (

) side:
The manipulated output value under the stable condition decreases by the Manual reset value.
Attribute:
R/W
When the integral function is enabled, the Manual reset is RO.
Digits:
7 digits
Number of data:
2 (Data of each channel)
Data range:

100.0 to +100.0 %
Factory set value:
0.0
Related parameters:
Integral time (P. 9-23)
Function:
This is the function used to manually correct the offset when in Proportional (P)
control or PD control.
Offset means the deviation of the actual when the manipulated output value
becomes stabilized (stable state). If the manual reset value varies, the manipulated
output value also changes.
