5701 Installation Information
Caution
This option contains ESD sensitive parts. Observe static control precautions when handling, installing,
and servicing this option.
1. Use the Fiber Optic Cable Cutter (LA385204) to dress the fiber optic cable connecting to the option card. The
cable must be cleanly and squarely cut to work properly. The Microtach encoder end of the fiber optic cable
requires a red fiber optic plug (CI055069) for termination.
2. Loosen the screws on the metal fiber optic connector on the feedback board and insert the cable. Carefully
push the cable into the connector until it is fully engaged. Retighten the screws.
3. Refer to Chapter 4 for calibration instructions.
The 5701 Microtach encoder is a 1000 PPR incremental encoder with digitally encoded fiber optic output. The option
card su24 VDC power to the encoder and decodes the fiber optic encoder signal. The controller supplies the
+24 VDC through terminals G3 and G4. Connect an ex24 VDC supply through the option card to terminal G2
(see Figure A.5) if the cont24 VDC supply is at capacity and unable to provide sufficient power.
Figure A.4 shows the Microtach receiver connected to the 5701 Microtach. The power terminals in the encoder are
marked ‘+’ and ‘-’.
The 5701 Microtach encoder has several mounting options. See the catalog for the mounting option you require.
Caution
The 5701 Microtach encoder is not suitable for use in a hazardous area.
