Operating Instructions
Connecting an Inhibit cable
This product provides an interface connection for an Inhibit input. A label is provided near
the connector.
To connect an Inhibit cable:
Verify that the power switch is in the off position
X X
Connect the interface cable to it's connector
X X
Tighten the cable connector screws until they are snug
X X
Pin Signal Description
1 GND Signal ground
2 Inhibit 1 GND to inhibit, open to enable
3 Inhibit 2 GND to inhibit, open to enable
Connecting a limit switch input cable
Notice
A risk of property damage exists if Limit Enable inputs are not properly
connected. Limit Enable inputs are available on the Axis Motor connector
and the Limit Switch connector. To avoid the hazard use only one pair of
Limit Enable inputs per axis. Never use the Limit Enable inputs from both
connectors. If both are used, limit switch function is severely impaired.
This product provides an interface connection for limit switch inputs. A label is provided
near the connector.

Pin Signal Description
1 X axis GND to enable output current in one polarity, open or DC 5 V
Limit to inhibit. Typically used with grounded, normally closed limit
/Pos Enab switches.
2 X axis GND to enable output current in opposite polarity, open or DC 5 V
Limit to inhibit. Typically used with grounded, normally closed limit
/Neg Enab switches.
3 Y axis GND to enable output current in one polarity, open or DC 5 V
Limit to inhibit. Typically used with grounded, normally closed limit
/Pos Enab switches.
4 Y axis GND to enable output current in opposite polarity, open or DC 5 V
Limit to inhibit. Typically used with grounded, normally closed limit
/Neg Enab switches.
5 Z axis GND to enable output current in one polarity, open or DC 5 V
Limit to inhibit. Typically used with grounded, normally closed limit
/Pos Enab switches.
6 Z axis GND to enable output current in opposite polarity, open or DC 5 V
Limit to inhibit. Typically used with grounded, normally closed limit
/Neg Enab switches.
