Display unit (J105)
J105 can select the display units for monitoring PID feedback value with the multi-function keypad (TP-A1-E2C).
Setting “0” selects the factory default unit for the PID feedback value.

Maximum scale/minimum scale (J106, J107)
The PID control values can be converted to a physical quantity that is easy to recognize and displayed accordingly.
Set the maximum scale “PID command value/ display for 100% of a PID feedback value” with J106 and the
minimum scale “PID command value/ display for 0% of a PID feedback value” with J107
The displayed value is determined as follows:
Display value = (PID command value (%)) / 100 * (Max. scale - Min. scale) + Min. scale
• Data setting range: (Max. scale and min. scale) -999.00 to 0.00 to 9990.00

PID multistep command 1 to 3 (J136, J137 and J138)
A PID command value can be given by the PID multistep command and selected by digital inputs programmed with
“PID-SS1” and “PID-SS2” functions. Assign the digital input terminals with “PID-SS1” and “PID-SS2” (
