Cause

1. The drive and motor types do not match.
2. A parameter checksum error exists in the bus-type incremental encoder ROM, or no parameters are stored
3. Drive fault

Corrective action

1. Confirm whether the drive and servo motor are Inovance SV660N series products. Replace them with a mutually compatible drive and motor.
2. Check whether the Inovance standard encoder cable is used. See Compatible cables for cable specifications. Ensure the cable has no damaged insulation or broken wires, terminals at both ends have no poor contact, and connections are secure. Measure signals at both ends of the encoder cable: PS+, PS-, +5V, GND; check whether the signals at both ends are consistent. Refer to the hardware wiring for signal definitions. Use the Inovance standard encoder cable, ensure secure terminal connections at the motor end, and tighten the screws at the drive end. Replace the encoder cable if necessary. Do not bundle the encoder cable with power cables (R S T, U V W); route them separately.
3. If the fault is still reported after powering on again, replace the servo drive.
