This manual introduces the pre-PID control function of the FR-F500-CH series inverter, including function overview, system structure, parameter setting and other contents.
The FR‑F500‑CH series speed governor provides pre‑set PID control for up to four motors used in pumps or fans. The document describes how to configure motor count, switching mode, and PID parameters using the Pr.500‑Pr.501 settings.
System composition, wiring diagrams, and detailed parameter tables are included, covering auxiliary motor start/stop frequencies, delay times, MC interlock settings, and output‑interrupt detection. The manual also lists required external equipment and safety considerations for proper installation and operation. This manual is written in Chinese.
| Auxiliary Motor 1 Start Frequency | 0–120 Hz (default 50 Hz) |
|---|---|
| Auxiliary Motor 1 Stop Frequency | 0–120 Hz (default 0 Hz) |
| Auxiliary Motor Start Delay (Pr.515) | 0–3600 s, step 0.1 s (default 5 s) |
| Auxiliary Motor Stop Delay (Pr.516) | 0–3600 s, step 0.1 s (default 5 s) |
| MC Interlock Switch Time (Pr.502) | 0–100 s, step 0.1 s (default 1 s) |
| Startup Waiting Time (Pr.503) | 0–100 s, step 0.1 s (default 1 s) |
Set parameter Pr.501 "电机切换选择" to 0 for basic, 1 for alternating, or 2 for direct mode.
Assign the X24 signal to any of Pr.180‑Pr.186; X24 ON selects positive action, X24 OFF selects reverse action.
Adjust parameter 515 "辅助电机启动延迟时间" to the desired number of seconds.
The factory default start frequency is 50 Hz.
