官方故障排除步驟
Message value: Drive object: SERVO Reaction: OFF2 (NONE, OFF1, OFF3) Acknowledge: IMMEDIATELY Cause: The permissible motor limit current was exceeded. - effective current limit set too low. - current controller not correctly set. - motor was braked with an excessivel y high stall torque correction factor. - V/f operation: Up ramp was set too short or the load is too high. - V/f operation: Short-circuit in the motor cable or ground fault. - V/f operation: Motor current does not match the current of Motor Module. Note: Synchronous motor: Limit current= 1.3 * p0323 Induction motor: Limit current= 1.3 * r0209 Remedy: - check the current limits (p0323, p0640). - check the current controller (p1715, p1717). - reduce the stall torque correction factor (p0326). - increase the up ramp (p1318) or reduce the load. - check the motor and motor cables for short-circuit and ground fault. - check the Motor Module and motor combination.
