Common faults
What usually fails on a unit like the KIRNER-330-1-D550
Stepper motors and drives are simple but run in demanding, fast-indexing duty. Drive faults usually sit in the output stage or supply; motor faults in bearings, windings and connectors.
Lost steps and stalling
Weak drive current, a failing supply, mechanical binding or a worn motor.
Drive output stage failure
Shorted output transistors after a winding or cable fault.
Overheating
Motor current set too high, or drives without enough cooling.
Bearing wear and noise
Worn motor bearings cause noise, resonance and position errors.
Connector faults
Loose or corroded connectors give erratic movement.
Motor
Motors are checked for winding insulation, bearings and feedback, and run after repair. If it carries an encoder, the encoder is checked for correct signals and alignment.
First checks
What to check before calling an engineer
Isolate and lock out the supply, and wait for stored energy to discharge, before opening anything.
Safe for plant staff
- Check the mechanism turns freely by hand with power off.
- Check connectors and cables.
- Note the drive's alarm LED state.
Leave to a specialist
- Drive board repair.
- Setting current and microstepping to suit the load.
