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.

Periodic Inspection
WARNING! Electrical Shock Hazard. Do not connect or disconnect wiring while the power is on. Failure to
comply can result in serious personal injury. Before servicing the drive, disconnect all power to the equipment.
The internal capacitor remains charged even after the power supply is turned off. The charge indicator LED
will extinguish when the DC bus voltage is below 50 Vdc. To prevent electric shock, wait at least one minute
after all indicators are OFF and measure the DC bus voltage level to confirm safe level.
