Troubleshooting　linear actuator

Zip Chain Actuator

*Most ZCA problems are caused by improper lubrication, improper selection, or improper installation.
If any trouble occurs, please take appropriate measures according to this Troubleshooting guide.

1 Damage to the drive unit
2 Input shaft damage
3 Bearing damage
4 Chain damage and abnormal wear
5 Abnormal noise from the chain

1 Damage to the drive unit
Cause 1 overload countermeasure Reduce the load or change the ZCA to one with the appropriate capacity.
Cause 2 Inappropriate support countermeasure Mount the ZCA on a sturdy stand and center it accurately.
Cause 3 impact countermeasure Install shock absorbers to prevent shocks.

2 Input shaft damage
Cause 1 Poor centering countermeasure The use of cylindrical couplings etc. can easily cause damage to the shaft. Please use ECHT-FLEX coupling. Adjust to the required concentricity.
Cause 2 Excessive overhang load countermeasure Adjust the load so that it is below the catalog value.
Cause 3 Overload, shock load countermeasure Reduce the load or change the ZCA to one with the appropriate capacity.
Cause 4 Excessive input countermeasure Please use safety devices to prevent shock loads.
Return to list
3 Bearing damage
Cause 1 overload countermeasure Reduce the load or change the ZCA to one with the appropriate capacity.
Cause 2 Excessive overhang load countermeasure Adjust the load so that it is below the catalog value.
Cause 3 Coupling misalignment countermeasure The use of cylindrical couplings etc. can easily cause damage to the shaft. Please use ECHT-FLEX coupling. Adjust to the required concentricity.
Cause 4 Coupling axial direction adjustment countermeasure Adjust the position and length of the coupling so that no axial load is applied to the input shaft.
Return to list
4 Chain damage and abnormal wear
Cause 1 overload countermeasure Reduce the load or change the ZCA to one with the appropriate capacity.
Cause 2 Poor adjustment or installation countermeasure Reduce the load or change the ZCA to one with the appropriate capacity.
Return to list
5 Abnormal noise from the chain
Cause 1 Lateral load countermeasure Install a guide or similar to prevent lateral load from being applied.
Cause 2 Poor lubrication countermeasure Refer to section 5. Maintenance and Inspection in Instruction Manuals and perform inspections and necessary lubrication.
Return to list
6 Abnormal drive surface temperature (over 60°C)
Cause 1 overload countermeasure Reduce the load or change the ZCA to one with the appropriate capacity.
Cause 2 Poor lubrication countermeasure Refer to section 5. Maintenance and Inspection in Instruction Manuals and perform inspections and necessary lubrication.
Cause 3 Poor centering countermeasure The use of cylindrical couplings etc. can easily cause damage to the shaft. Please use ECHT-FLEX coupling. Adjust to the required concentricity.

7 It does not turn when a load is applied (the chain does not move forward or backward)
Cause 1 Voltage drop countermeasure Check the wiring length
Cause 2 Gear wear countermeasure Repaired at a specialized factory
Cause 3 Overload operation countermeasure Reduce the load
Return to list
8 The chain moves in the opposite direction
Cause 1 Wiring error countermeasure Check the wiring
Return to list
9 Abnormal fever
Cause 1 Overload operation countermeasure Reduce the load
Cause 2 Start/stop frequency is too high countermeasure Reduce frequency
Cause 3 Bearing damage countermeasure Repairs and replacements
Cause 4 Voltage is too high or too low countermeasure Checking the voltage
Cause 5 High braking frequency countermeasure Reduce braking frequency
Cause 6 Large load torque and load inertia countermeasure Reduce the load
Return to list
10 loud noise
Cause 1 Continuous noise Bearing damage/gear wear countermeasure Repaired at a specialized factory
Cause 2 Intermittent noise Scratches or foreign matter in the gears countermeasure Repaired at a specialized factory
Return to list
11 Large vibrations
Cause 1 Gear and bearing wear countermeasure Repaired at a specialized factory
Cause 2 Improper installation/loose bolts countermeasure Retightening
Return to list
12 Grease leaks
Cause 1 Looseness of fastening parts countermeasure Retightening
Cause 2 Oil seal damage countermeasure exchange
Return to list
13 The brakes don't work
Cause 1 Wiring error countermeasure Checking the wiring
Cause 2 Defective switch countermeasure Repairs and replacements
Return to list
14 Braking is weak
Long braking time
Cause 1 Oil and dirt adhere to the lining countermeasure Disassembly and cleaning
Cause 2 Lining life countermeasure Repairs and replacements
Cause 3 Load inertia is too large countermeasure Reduce the load inertia
Cause 4 AC internal wiring wiring countermeasure DC external wiring wiring
Return to list
15 The motor does not turn (the chain does not move forward or backward)
The motor generates abnormal heat
Thermal relay does not operate
Brake noise is loud
Cause 1 Brake wiring error countermeasure Checking the wiring
