RUN

PID Accel/Decel Time

Raises or lowers the PID setpoint using the acceleration and deceleration times set to the drive. This is a soft-starter for the PID setpoint.

0.0 s

(0.0 - 6000.0 s)

The drive usually uses the acceleration and deceleration times set in C1-xx [Accel and Decel Times], but when PID control is enabled, the drive applies C1-xx after PID output. If you frequently change the PID setpoint, the drive responsiveness decreases. When resonance with PID control causes hunting, overshoot, or undershoot, set b5-17 for longer acceleration and deceleration times.

Decrease C1-xx until hunting stops, then use b5-17 to check the acceleration and deceleration. To enable and disable the setting in b5-17 through an MFDI terminal, set PID Soft Starter Disable [H1-xx = 34].
