DBC 130(F30i Series) DBC130ALE2A 1.4 2004 Hyd. Pump Motor Overload 1) Description Hyd. An excessive electric current is detected in the hydraulic pump motor or the lubricant pump motor of the spindle head. 2) Cause of problem ① The hydraulic pump motor, the lubricant pump motor of the spindle head, or the power cable is burnt out. ② The circuit breaker that detects the excessive current is overloaded or defective itself. 3) Action ① Check the hydraulic pump motor, the lubricant pump motor of the spindle head, or the power cable if there is a problem. Repair or replace the defective part if necessary. ② Check the circuit breaker for the load settings and make correction if necessary.
If the circuit breaker itself has an error, replace it with a new one. (You can detect a defective circuit breaker by checking the resistance on either circuit of M212 or 1L+) Overload settings QM31 : 5.5 Kw : 24 A QM33 : 3.7 Kw : 16.1 A QM34 : 0.1 Kw : 0.7 A QM10 : 1.5 A QM73 : 1.5 Kw : 7 A 9 Part Name Part No. Symbol Spec.
