4.8 WIRING THE ENCODER
The standard
SILVER
LINE encoder uses a 10-pin ribbon cable connector. It is wired according to the HEDL ®
standard from Hewlett-Packard. Refer to Figure 4-2 (page 4-17). If you are using a standard
SILVER
LINE encoder
or any encoder compatible with the HEDL standard, you may connect the encoder directly to the S/O velocity-loop
option PCB with a ribbon cable. If your environment requires discrete wires in place of ribbon cable, substitute
appropriate connectors such as AMP 102387-1 shells.

Always strain relieve the encoder cable. If the encoder cable is disconnected or cable connections are broken, the
motor will run away. Strain relieve at the connectors and along the length of the cable if necessary. Be particularly
thorough when providing strain relief in environments with significant vibration.
On
SILVER
LINE motors, strain relief for the encoder cable is provided with a wire tie which secures the ribbon
cable connector and line driver to the encoder body. Use a 0.1" wide, 4.5" long wire tie such as Richo WIT-18R.
This wire tie fits securely in notches of the standard
SILVER
LINE encoder ribbon-cable connector (Amp 746285-
1). Two steel hoops are attached to the encoder body through which the wire tie is threaded. Note that the connector
does not have an integral strain relief as the version with strain relief cannot be fastened reliably with a wire tie. Do
not interchange the black encoder connector with blue connectors which are provided for the S/O velocity loop
option card.
As the connector does not provide strain relief for the cable, this function is also provided by the wire tie. Assemble
as shown below: fold the ribbon cable across the back of the connector to form a small loop and install the wire tie
securely, preferably with a wire-tie gun or similar device.
