PID compensation
-100.0 to 100.0%
0
The PID compensation value = maximum PID target value × Pr.08-17. For example, if the maximum operation
frequency Pr.01-00 = 60 Hz, and Pr.08-17 = 10.0%, the PID compensation value increases the output frequency
6.00 Hz (60.00 Hz × 100.00% × 10.0% = 6.00 Hz).

0
0: The unit for Pr.08-10 and that for Pr.08-11 switch to frequency. The settings are between 0.00–599.00 Hz.
1: The unit for Pr.08-10 and that for Pr.08-11 switch to percentage. The settings are between 0.00 to 200.00%.

PID control flag
bit 0 = 1: PID running in reverse follows the setting for Pr.00-23.
bit 0 = 0: PID running in reverse refers to PID’s calculated value.
bit 1 = 1: two decimal places for PID Kp
bit 1 = 0: one decimal place for PID Kp
2
bit 0 = 1: PID running in reverse function is valid only when Pr.08-21=1.
bit 0 = 0: If the PID calculated value is positive, the direction is forward. If the PID calculated value is negative, the
direction is reverse.
When the bit1 setting changes, the Kp gain does not change. For example: Kp = 6. When Pr.08-23 bit1 = 0, Kp =
6.0; when Pr.08-23 bit1 = 1, Kp = 6.00.
There are three scenarios for the sleep and wake-up frequency.
1) Frequency Command (PID is not in use, Pr.08-00 = 0. Works only in VF mode)
When the output frequency ≤ the sleep frequency and the drive reaches the preset sleep time, then the drive is in
sleep mode (0 Hz). When the Frequency command reaches the wake-up frequency, the drive starts to count the
