How can resolve problem F1 Overcurrent fault in siemens V20 Drive ?
Cause : Overcurrent fault -
• Motor power (P0307) does not correspond to the inverter power (r0206).
• Motor lead short circuit
• Earth faults
r0949 = 0: Hardware reported
r0949 = 1: Software reported
r0949 = 22: Hardware reported
Check the following:
• Motor power (P0307) must correspond to in- verter power (r0206).
• Cable length limits must not be exceeded.
• Motor cable and motor must have no short- circuits or earth faults.
• Motor parameters must match the motor in use.
• Value of stator resistance (P0350) must be correct.
• Motor must not be obstructed or overloaded.
• Increase ramp-up time (P1120)
• Reduce starting boost level (P1312)
