What F30022 means

Power unit: Monitoring U_ce p. 714

Common causes

• Reaction: OFF2 p. 714
• In the power unit, the monitoring of the collector-emitter voltage (U_ce) of the semiconductor has responded. p. 714
• Possible causes: p. 714
• - power supply of the IGBT gating module missing. p. 714
• - short-circuit at the power unit output. p. 714
• - defective semiconductor in the power unit. p. 714
• Fault value (r0949, interpret binary): p. 714
• Bit 0: Short-circuit in phase U p. 714
• Bit 1: Short-circuit in phase V p. 714
• Bit 2: Short-circuit in phase W p. 714
• Bit 3: Light transmitter enable defective p. 714
• Bit 4: U_ce group fault signal interrupted p. 714
• See also: r0949 (Fault value) p. 714
• Remedy: p. 714
• - check the power supply of the IGBT gating module (24 V). p. 714
• - check the power cable connections. p. 714
• - select the defective semiconductor and replace. p. 714

What to do

1. Acknowledge: POWER ON p. 714
2. - fiber-optic cable interrupted. p. 714
3. - check the fiber-optic cable and if required, replace. p. 714
