The Family FESM-550S is a 550W (3/4 HP), 110V/220V variable speed, brushless DC servo motor designed for industrial sewing machines (0-3450 RPM). It features an adjustable speed dial, a needle positioner-compatible shaft, and a digital controller (often labeled TH-550S) to adjust speed (P-00 or similar), maximum RPM, and motor rotation direction.
Key Features and Setup (Based on FESM-550N/TH-550S):
- Speed Adjustment: The dial controls the maximum speed; the foot pedal acts as a variable speed controller within that range.
- Rotation Direction: Can be reversed via the controller settings (check P-01 or similar, typically 0 for counter-clockwise, 1 for clockwise).
- Controller Parameters: Common parameters include max speed (P-00), acceleration, and motor direction.
- Installation: Mounts directly to the table with a standard 3-hole mount.
Common Troubleshooting:
- Motor not running/Error codes: Check power supply (110V), check the plug connections, and ensure the pedal is connected properly.
- No speed change: If the potentiometer knob does not alter speed, it may indicate a faulty, disconnected panel or a circuit failure.
Settings (General for TH-550S Series):
- Note: Access parameters by pressing 'P' and adjust with +/- buttons.
- P-00: Maximum Speed Setting (e.g., 3000-3450 RPM).
- P-01: Direction of Rotation (0=CCW, 1=CW).
- P-06: Speed of Motor Stop (0-30).
For detailed wiring and parameter menus, it is recommended to refer to the MaquinasUniao pdf for FESM-550N as it is similar to the 550S.
