P7.25 PID Mode Selection
Range/Units (Format: 16-bit binary)
0: Old PID mode, Kp, Kp•Ki, Kp•Kd are dependent/serial
1: New PID mode, Kp, Ki, Kd are independent/parallel
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
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
IF Remote & Local, P4.00 & P4.01 = 2: set P4.02~04 = 3
P7.02 (PID Setpoint Source) Read Only
P7.25 = 1: Independent/Parallel Connection
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
IF Remote & Local, P4.00 & P4.01 = 2: set P4.02~04 = 3
P7.02 (PID Setpoint Source) Read Only
