MAINTENANCE AND INSPECTION

9.1

Daily Inspection

Followings are the daily checking points during operation:

앫

Rotation speed of motor

앫

Environmental condition of the inverter drive

앫

Activation of cooling system

앫

Extraordinary vibration or airborne noise

앫

Over heating or discoloration

For detailed checking operation please refer to the Instruction manual of FR-D700 SC.

9.2

Periodic Inspection

It is recommended to make the following checks periodically:

앫

Check for loose screws in the terminal block. Retighten any loose screws.

앫

Check for dust accumulation on the inverter. Clean the heat sink and the cooling fan of the inverter.

앫

Check for unusual noise generated from the inverter. Retighten installation screw.

앫

Check for the operation condition. Keep the operation condition of inverter as written in the Inverter FR-D700 SC Instruction Manual.

앫

For detailed maintenance operation please refer to the Instruction manual of FR-D700 SC.

9.3

Checking and Testing of Restart Prevention

To avoid systematic faults, a test even for faulty demands of the safety function has to be performed in order to check the correct
function of the restart prevention.
This test shall be carried out at system installation, any software changes, parameterization changes, and/or at least once per year.
For detailed checking procedure refer to the "Transistorized Inverter FR-D700 SC Safety stop function Instruction Manual".

앫

To avoid an electric shock hazard, insert the magnetic contactor (MC) between AC power supply and FR-D700 SC.
Open the contact of MC and keep away from drive for discharging time (10 minutes) before performing any work on the drive.
And verify that the voltage on the bus capacitors has discharged before Measure the DC bus voltage at the P/+ and N/–
terminals or test points (refer to

"Main circuit terminal specifications" for locations).

The voltage must be zero.

앫

Do not carry out a megger (insulation resistance) test on the control circuit of the inverter. It will cause a failure.

Any misuse of safety function could lead to personal injury or death, property damage, or economic loss.
To ensure that the system complies fully with requirement of safety, make a system-level risk assessment and adequate verification
for systematic failure.
