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
