Common faults
What usually fails on a unit like the EK1 87-60
Servo and spindle motors usually fail mechanically or in their feedback device rather than in the windings. Bearings, encoders, brakes and seals can be replaced and the motor tested under load.
Bearing wear
Noise, vibration and heat from worn bearings, often caused by coolant ingress, belt tension or misalignment.
Encoder or resolver faults
Feedback alarms, position errors or a motor that runs away. The encoder may be replaceable, but it then needs aligning to the rotor.
Winding insulation failure
Earth faults and overcurrent alarms from coolant or oil getting into the motor or connector.
Holding brake problems
A brake that doesn't release causes overload alarms; one that doesn't hold lets vertical axes drop when disabled.
Connector and cable damage
Corroded or loose power and feedback connectors cause intermittent alarms that look like drive faults.
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 connectors for coolant, oil and corrosion.
- Listen for bearing noise with the motor running unloaded, if it is safe to do so.
- Have the winding insulation tested with the motor cable disconnected from the drive.
Leave to a specialist
- Removing or replacing an encoder: it has to be realigned to the rotor.
- Changing bearings on spindle motors.
- Working on vertical axes without the load supported.
Getting it fixed
How to get the EK1 87-60 repaired
What to send with it
- The motor, with its encoder and connectors as fitted.
- The drive alarm that appeared, and whether the motor was noisy or hot.
- The motor nameplate photo.
Onsite or ship-in
Technicians work onsite from our Hyderabad base and travel to plants across India; anything that can be removed can also be sent to MachineryFix from anywhere in the country.
Warranty. Repairs carry a warranty of 30 days to 6 months, depending on the item and the repair; the exact term is confirmed before work starts.
FAQ
EK1 87-60 repair questions
Can the encoder on the Groschopp EK1 87-60 be replaced?+
Often, yes. The replacement has to be aligned to the motor's rotor so commutation stays correct, which is done during the repair and checked under power.
Can a motor with coolant in it be saved?+
Usually, if the windings haven't broken down. The motor is cleaned, dried, re-sealed and insulation-tested before any decision on rewinding.
Does the Groschopp EK1 87-60 have to be sent in, or can an engineer come to the plant?+
Either. An engineer can diagnose it in place and repair it there or take it away, or the unit can be sent to MachineryFix from anywhere in India. The diagnosis and repair cost are confirmed before any work starts.
Is MachineryFix connected to Groschopp?+
No. Groschopp and the model name are used only to identify the equipment. MachineryFix is an independent repair service and is not affiliated with or endorsed by Groschopp.
