No. (Hex.) Name Description Default (Range) b5-01 (01A5) PID Mode Setting Sets the type of PID control. 0 (0 - 8) 0 Disabled 1 Standard Enables PID control. The drive does D control on the difference between the feedback value and the PID setpoint output through U5-02 [PID Input]. 2 Standard (D on feedback) Enables PID control. The drive does D control on the feedback output through U5-06 [PID FdbkDif PID Fdbk]. 3 Fref + PID Trim Enables PID control. The drive adds the frequency reference to the PID output. The drive does D control on the difference between the feedback value and the PID setpoint output through U5-02 [PID Input]. 4 Fref + PID Trim (D on feedback) Enables PID control. The drive adds the frequency reference to the PID output. The drive does D control on the feedback output through U5-06 [PID FdbkDif PID Fdbk]. 5 Same as 7series & prior, b5-01=1 6 Same as 7series & prior, b5-01=2 7 Same as 7series & prior, b5-01=3 8 Same as 7series & prior, b5-01=4 Note: Use settings 5 to 8 instead of settings 1 to 4 when the drive is a replacement for Varispeed F7.
