22 Installation & Hook-Up
Wiring the Drives Signal for a
Compact When using the REC with an S Class Compact, the drive reference
signals (+/-10V) are passed from the Compact to the REC at
terminals 8, 9, and 10 on plug A (Axis 1), and at terminals 3, 4, and 5
on Plug B (Axis 0). To wire the drives signal:
1. Connect the drive signal to the servo amplifier using a twisted,
shielded cable (Belden 9501 or equivalent).
2. Wire the cable leads to the appropriate Power & Drives plugs ofr
the required axis. Figure 2.12 shows where to connect the drives
reference signals to the Power & Drives connector.
Both Axis 0 and Axis 1 can have drive signals present at their
connectors.
Note: You do not need to wire the drive reference signal to the 1394
because it handles the reference signal output internally.

Important: Anchor the cable so that no more than 2 feet of cable is
left unsupported. The excessive weight of an unanchored
cable could pull the plug out of the connector.
Connecting a Fault Relay The REC is equipped with a fault detector that handles internal logic
voltage malfunctions and resolver phase loss faults. The fault detector
consists of:
• An internal relay contact output that opens for each axis
• An LED indicator that turns red for each axis
• An encoder driver disabler for each axis
