4 Maintaining/Troubleshooting

In this chapter

This chapter covers maintenance and troubleshooting of the 6410
unit.

4.1 Main tain ing the 6410 Drive

Introduction

The 6410 drives are designed for minimum maintenance.  The
following cleaning procedure, performed as needed, will minimize
problems due to dust and dirt build-up.

Procedure

Remove superficial dust and dirt from the unit using clean, dry,
low-pressure air.

4.2 Trou ble shoot ing the 6410 Drive

Introduction

The 6410 has an “enabled” output which is on when the drive is
enabled and off when the drive is disabled or faulted due to any of 
the following:

Output overcurrent (line-to-line or line-to-neutral short)

Bus overvoltage

Low voltage supply out of tolerance.
