At Dynapar, we employ a professional staff of Application Engineers whose full time responsibility is to help you select the proper encoder or resolver, install it correctly and get it up and running to your satisfaction. These friendly and knowledgeable people are available during business days from 7:30 am to 4:30 pm Central Standard Time (CST).

Before You Call

Misunderstanding manual instructions or omitting installation steps is the most common source of error. For complete trouble-shooting guidelines on Dynapar or Northstar encoder installation, mounting and wiring, refer to your specific encoder specification/technical data sheet or our Dynapar General Wiring and Installation handbookor NorthStar Troubleshooting Tipsfirst.

General Encoder Installation Guidelines

Things to avoid while mounting your encoder or resolver:

• Do not shock the encoder (using a hammer)
• Do not subject the encoder to axial or radial shaft stresses
• Do not disassemble the encoder
• Do not use a rigid coupling
• Do not tool the encoder or its shaft
• Do not use makeshift techniques to mount the encoder

Things to avoid in wiring your encoder:

• Never connect or disconnect the encoder connector or wiring while power is ON.
• Power should always be connected to the + (positive) side of DC power.
• Common should always be connected to the – (negative) side of DC power.
• Never connect A, B, or Z to the + or – side of DC power.
