1.0 OVERVIEW
This board interface is used for the connection between Acorn CNC and the
CLEARPATH SERVO DRIVE.
2.0 FEATURES
•Enable and disable the drives.
•Splits Step and Direction signals from axis X or Y to allow wiring an
additional axis using the same signals.
•The board can be activated and start monitoring for a driver fault using the
axis enable or NO_FAULT signal.
•Electromechanical relay reflects the ACTIVE / FAULT Status of a servo.
•Power terminal (12VDC / 24VDC).
•Status LEDs for fault axis and relay status.
•Connector CONMOLEX 8P for driver CLEARPATH.
•Pluggable Screw-On Terminals

4.0 REQUIREMENTS
4.1 Power Requirements
Regulated 12/24VDC is required to power this board.
WARNING
Check the polarity and voltage of the external power source and connect the 12VDC or
24VDC and GND. Overvoltage or reverse-polarity power applied to these terminals can
cause damage to the board, and/or the power source.
5.0 TERMINAL POWER
Regulated +12VDC or +24VDC is required to power this board.

6.0 ACTIVATING THE BOARD
Fault monitoring starts when the board is active. When the board is active the relay is
activated and the green LED is on.
Two conditions must be met to activate the system and start monitoring for a fault:
1. At least one axis is receiving an active enable signal from the ACORN board or
the jumper is set not to monitor the ACORN enable signals.
2. The contacts on the NO_FAULT terminal are closed. You can configure a relay
and read the NO_FAULT signal from the ACORN, or you could just put a jumper
on it if not used.
The board can be activated by the axis enable or the NO_FAULT signal, or a
combination of both signals. It could also be hardwired to be permanently active if both
inputs are jumped.
6.1 Operation Sequence:
1. Once the board gets enabled, it will take 5 seconds in order for it to start
monitoring for a fault. This to preserve compatibility with some drivers which may
need time to activate.
2. If a driver faults, the relay will trip and the green LED will go off. An LED
indicating the which driver or drivers triggered the fault will light next to the RJ45
of the axis that tripped the fault.

7.0 JUMPER TO SELECT THE ACTIVE AXIS
Set of jumper as shown in the image
2-3: ON
Set of jumper as shown in the image
1-2: OFF
Note: Set the jumper to ON for connected axis and off if no drivers is connected.
8.0 SLAVE AXI’S SELECT JUMPER WITH X AXIS OR Y AXIS
Set jumper 2-3 for X slave

User’s Manual Page 5
Set jumper 1-2 for Y slave
Remove jumper if not use axis slave
9.0 JUMPER TO SELECT THE ENABLE
Use Software Enable to keep the driver active only while the system is active. Set of
jumper as shown in the image.
Use Hardware Enable to keep the driver enabled all the time.
