7-2 Items to Check During Operation
Table 7-1 Items to Check During Operation
Does abnormal sound or vibration
generate?
- Is the housing deformed because the installation surface is not flat?
- Is Insufficient rigidity of the installation base generating resonance?
- Is the shaft center aligned with the driven machine?
- Is the vibration of the driven machine transmitted to the gearmotor or reducer?
Is the surface temperature abnormally high?
- Does the voltage rise or drop substantially?
- Is the ambient temperature too high?
- Does the current flowing to the gearmotor exceed the rated current shown on the nameplate?
If any abnormalities are found, immediately stop operation and contact the nearest authorized maintenance shop.

Notes: 1. Brake type may differ depending on specification. Check the nameplate.
2. Brake torque will change according to operating environment, operating conditions, the condition of the friction surface, etc. In
particular, brake torque may not be at the prescribed level for initial operation, and after a long period of inactivity. In such a case
turn the brake on and off under as light load as possible to contact the brake’s friction surfaces.
3. Brake activation delay time will change according to the brake’s wiring circuit. Select the optimum circuit for the application.
