Note

To activate PID mode, one of the TB-13 inputs (P121...P123) must be used to select the Auto Reference that matches the desired PID setpoint reference. If the selected PID setpoint reference uses the same analog

signal as the PID feedback (P201), an fault will occur.

Example: The desired PID setpoint reference is the keypad (s and t).

Set TB-13x = 6 (Auto Reference: Keypad):

•TB-13x = closed: PID mode is active

•TB-13x = open: PID mode is disabled and the drive speed will be controlled by the reference selected in P101.
