Symptom
Possible Cause
Possible Solution
Machine does not start or a circuit breaker trips.
1.(First time operation only) Lathe may be wired with the incorrect phase polarity.
2.Emergency stop
3.Spindle ON/OFF switch is at fault.
4.Power supply is switched OFF at master power switch or breaker.
5.Wall fuse/circuit breaker is blown/ tripped; short in electrical system;
6.Fuse has blown in machine electrical box due to thermal overload.
7.One or more kill switches are engaged.
8.Motor connection wired incorrectly.
9.Oil pump motor operating, but oil is not seen pumping past sight glass.
10.Limit/kill switch at fault.
11.Contactor not getting energized/has burnt contacts.
12.Wiring is open/has high resistance.
13.Motor is at fault.
14.Frequency drive unit is at fault.
1.Correct phase polarity (refer to Page 16 for details).
2.Rotate button clockwise until it pops out to reset it for operation; replace if not working properly.
3.Move the spindle ON/OFF lever to ON; replace bad switch.
4.Make sure master power switch and circuit breaker are turned ON.
5.Verify circuit is rated for machine amp load; troubleshoot and repair cause of overload; replace weak breaker; find/repair electrical short.
6.Replace fuse; determine if overload is due to heavy operation; ensure power source has high enough voltage and cord is correctly sized.
7.Verify electrical box door, chuck guard, gear cover, spindle, and brake switches are not engaged. Headstock oil pump is not pumping, or is wired with the incorrect phase polarity. Correct pump phase polarity, refer to Page 16.
8.Correct motor wiring connections.
9.Prime pump, fill headstock oil tank to full, or replace oil pump.
10.Test all limit/kill switches and replace as necessary.
11.Test for power on all legs and contactor operation. Replace unit if faulty.
12.Check for broken wires or disconnected/corroded connections, and repair/replace as necessary.
13.Test/repair/replace.
14.Contact frequency drive manufacturer for list of authorized service providers in your area.
