This section is intended for the engineer or technician responsible for installing

the DC60 resolver based encoder. Information in this chapter includes installation

guidelines, links to online CAD files, and mechanical drawings.

1.1 Installation Guidelines

1.1.1 Electrostatic Discharge Prevention

Electrostatic discharge can damage the DC60 if the discharge is through the I/O connector. Follow these

guidelines when handling the unit.

1) Touch a grounded object to discharge static potential before handling the unit.

2) Work in a static-safe environment whenever possible.

3) Do not touch the pins of the I/O connector.

4) Do not disassemble the unit

1.1.2 Suitable Environment

The DC60 has an IP67 environmental rating and can be installed in most industrial environments, including

areas subject to washdown spray and temporary immersion.

The IP67 rating is contingent on the proper installation of the mating connector.

1.1.3 Shaft Loading

A flexible coupler should be used when connecting a DC60 to a drive shaft, because any mismatch in shaft

alignment will result in large radial or axial loading on the shaft of the encoder. Limit shaft loading to the fol-

lowing values. These values statistically yield an L10 life of 2X10

the bearings will have failed after 2X10

The effect is actually cubic. Cutting a shaft load in half will result in an eight fold increase in bearing life.

1.1.4 A Note on Cable Direction

All of the dimensional drawings in the

when using right angle connectors. Use this information to properly route cables when designing the DC60

mounting.
