Hello, Fault: F0002 Over Voltage Possible Causes: 1- DC-link voltage (r0026) exceeds trip level (P2172) 2- Over voltage can be caused either by too high main supply voltage or if motor is in regenerative mode. Regenerative mode can be cause by fast ramp downs or if the motor is driven from an active load. Diagnose & Remedy: Check the following: 1. Supply voltage (P0210) must lie within limits indicated on rating plate . 2. DC-link voltage controller must be enabled (P1240) and parameterized properly. 3. Ramp-down time (P1121) must match inertia of load. 4. Required braking power must lie within specified limits. NOTE: Higher inertia requires longer ramp times; otherwise, apply braking resistor. |
