Use b5-01 [PID Mode Setting] to select how the PID setpoint is input to the drive.

One of the inputs in Table 1 will be the PID setpoint.

When the input in Table 1 is disabled, either the frequency reference set in b1-01 [Frequency Reference Selection 1] or b1-15 [Frequency Reference Selection 2] will be the PID setpoint.

Table 1. Input Methods for the PID Setpoint

Input Methods for the PID Setpoint

Setting Value

MFAI terminal A1

Set H3-02 = C [Terminal A1 Function Selection = PID Setpoint].

MFAI terminal A2

Set H3-10 [Terminal A2 Function Selection] = C.

MEMOBUS/Modbus register 0006H

Sets MEMOBUS/Modbus register 000FH (Control Selection Setting) bit 1 to 1 (PID setpoint input). Enters the PID setpoint to MEMOBUS/Modbus register 0006H (PID Target, 0.01% units, signed).

Pulse train input terminal RP

Set H6-01 = 2 [Terminal RP Pulse Train Function = PID Setpoint Value].

b5-19 [PID Setpoint Value]

Set b5-18 = 1 [b5-19 PID Setpoint Selection = Enabled]. Enters the PID setpoint to b5-19.
Note:

If you set two inputs for the PID setpoint, it will trigger operation error oPE07 [Analog Input Selection Error].
