This manual introduces the front-end PID control function of the FR-F500-CH series soft starter, including functional overview, system structure, parameter setting, precautions, etc.
The FR‑F500‑CH series supplement provides instructions for using the pre‑set PID control function to operate pumps or fans with up to four motors. It describes how to select the motor action count (Pr.500) and the motor switching method (Pr.501) for basic, alternating, or direct modes.
Detailed sections cover system wiring, motor switching timing, output‑interruption detection, and a full list of parameter codes. The document also specifies default ranges for start/stop frequencies, delay times, and PID action selection, enabling precise configuration of the soft starter for various applications. This manual is written in Chinese.
| Auxiliary Motor 1 Start Frequency Range | 0–120 Hz (step 0.01 Hz, default 50 Hz) |
|---|---|
| Auxiliary Motor 1 Stop Frequency Range | 0–120 Hz (step 0.01 Hz, default 0 Hz) |
| Auxiliary Motor Start Delay Time | 0–3600 s (step 0.1 s, default 5 s) |
| Auxiliary Motor Stop Delay Time | 0–3600 s (step 0.1 s, default 5 s) |
| Output Interruption Detection Time | 0–3600 s (step 0.1 s, default 9999 s disables) |
The PID control function can operate up to four motors.
Parameter Pr.501 “电机切换选择” selects the motor switching mode.
PID action direction is set by the X24 signal and the value of Pr.128 (10‑30 for reverse, 11‑31 for forward).
