P7.25 PID Mode Selection
R/W 0719 41818
Range/Units Default
0: Old PID mode, Kp, Kp•Ki, Kp•Kd are dependent/serial
1: New PID mode, Kp, Ki, Kd are independent/parallel
0
NOTE: Refer to diagrams below for P7.25=0 and P7.25=1
• Kp = Proportional Gain/Control (P7.13)
• Ki = Integral Time/Control (P7.14)
• Kd = Derivative Value/Time (P7.15)
The Serial or parallel connection PID mode selections are explained in the 2 graphics found in the
detailed information found below.
P7.25 = 0: Dependent/Serial Connection
• P7.00 = 0 - OR -
• P7.00 = 3 or 4 & drive in Local/Hand - OR -
• P7.00 = 5 or 6 & drive in Remote/Auto - OR -
• P3.03~16 = 21 (PID Function Disable)

PID Setpoint can be sourced in Local Mode, Remote
Mode, or both Local and Remote modes, depending on
the setting of parameter P7.00 (PID Action/Mode).
IF Remote: set P4.00 = 0~4
IF Local: set P4.01 = 0~4
IF Remote & P4.00 = 2: set P4.02~04 = 1
IF Local & P4.01 = 2: set P4.02~04 = 2
