Recommended Daily Inspection

Table 6.1 outlines the recommended daily inspection for Yaskawa drives. Check
the following items on a daily basis to avoid premature deterioration in
performance or product failure. Copy this checklist and mark the "Checked"
column after each inspection.
Table 6.1 General Recommended Daily Inspection Checklist
Inspection
Category
• Inspect for abnormal oscillation or noise
Motor
coming from the motor.
• Inspect for abnormal heat generated
Cooling from the drive or motor and visible
discoloration.
• Verify the drive environment complies
Environment with the specifications listed in the
Installation section of this manual.
• The drive output current should not be
Load higher than the motor or drive rating for
an extended period of time.
Cooling • Inspect drive cooling fan operation.
Power Supply • Check main power supply and control
Voltage voltages.

Recommended Periodic Inspection

Table 6.2 outlines the recommended periodic inspections for Yaskawa drive
installations. Periodic inspections should generally be checked every 3-6 months;
however, the drive may require more frequent inspection due to poor environments
or rigorous use. Operating and environmental conditions, along with experience in
each application, will determine the actual inspection frequency for each
installation. Periodic inspection will help to avoid premature deterioration in
performance or product failure. Copy this checklist and mark the "Checked"
column after each inspection.
