Zip Chain Actuator
※Most troubles with the ZCA are due to lubrication, selection, and installation problems.
If any problem arises, follow this troubleshooting guide and take the appropriate measures.
Troubleshooting for motors
1 |
Damage to the drive section |
Cause 1 |
Overload |
Action |
Either reduce the load or switch to a ZCA with a proper capacity. |
Cause 2 |
Improper support |
Action |
Fix the ZCA to a stable frame and then accurately center it. |
Cause 3 |
Shock |
Action |
Install a damper unit to absorb the impact being added. |

Cause 1 |
Improper centering |
Action |
Shafts will easily break when using a cylindrical coupling and the like. Use Echt-Flex Couplings, then adjust to the required concentricity. |
Cause 2 |
Excessive overhung load |
Action |
Adjust the load to fall within catalog values. |
Cause 3 |
Overloads and impact load |
Action |
Either reduce the load or switch to a ZCA with a proper capacity. |
Cause 4 |
Excessive input |
Action |
Add a safety device to prevent impact load. |

Cause 2 |
Excessive overhung load |
Action |
Adjust the load to fall within catalog values. |
Cause 3 |
Improper centering of the coupling |
Action |
Shafts will easily break when using a cylindrical coupling and the like. Use Echt-Flex Couplings, then adjust to the required concentricity. |
Cause 4 |
Axial adjustment of the coupling |
Action |
Adjust the position and length of the coupling so that the input shaft will not receive axial load. |

Chain failure and abnormal wear |
Cause 1 |
Overload |
Action |
Either reduce the load or switch to a ZCA with a proper capacity. |
Cause 2 |
Poor adjustment and installation |
Action |
Either reduce the load or switch to a ZCA with a proper capacity. |
