CNC4PC C86ACCP6 CleartPath Connector Board

Overview

This board interface is used for the connection between AcornSix 6-axis CNC controller and the CLEARPATH SERVO DRIVE.

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 (24VDC).
• Status LEDs for fault axis and relay status.
• Connector CONMOLEX 8P for driver CLEARPATH.
• Pluggable Screw-On Terminals

Board Description

Image of the CNC4PC C86ACCP6 CleartPath Connector Board, a green printed circuit board with multiple green and white pluggable screw terminals, Molex connectors, jumpers, LEDs, and a relay. The board is designed for connecting a CNC controller to servo drives.

The board features:

• Pluggable Screw-On Terminals for Axis: Located on the left side for connecting axis signals.
• Jumper to Select Active Axis: Allows configuration for active axis selection.
• Power Terminal (24VDC): Includes a power LED indicator.
• Terminal NO FAULT: For monitoring driver fault status.
• Electromechanical Relay: Reflects the ACTIVE/FAULT status of the servo.
• CONMOLEX 8P Output Connector: For connecting the driver.
• Jumpers for Acorn Enable: Configurable for 1-2=ON or 2-3=OFF.
• Jumpers for Soft/Hard Enable: Configurable for 1-2=SOFT or 2-3=HARD.
• Pins for Acorn CNC: Interface for the Acorn CNC controller.

Requirements

Power Requirements

Regulated 24VDC@200mA is required to power this board.

WARNING: Check the polarity and voltage of the external power source and connect the 24VDC and GND. Overvoltage or reverse-polarity power applied to these terminals can cause damage to the board, and/or the power source.

Terminal Power

Regulated 12 or +24VDC@200mA is required to power this board.

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.

Images illustrating the NO_FAULT terminal jumper configuration. The left image shows jumper pins set to '1-2 ON'. The right image shows jumper pins set to '2-3 OFF'.

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.

Operation Sequence:

1. Once the board gets enabled, it will take 5 seconds in order for it to start monitoring for a fault. This is 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 which driver or drivers triggered the fault will light next to the RJ45 of the axis that tripped the fault.

Jumper to Select the Active Axis

Set of jumpers as shown in the image:

• 2-3: ON
• 1-2: OFF

Note: Set the jumper to ON for connected axis and off if no drivers are connected.

Images showing jumper settings for selecting the active axis. The top image shows the jumper set to '2-3: ON'. The bottom image shows the jumper set to '1-2: OFF'.

Jumper to Select the Enable

Use Software Enable to keep the driver active only while the system is active. Set of jumpers as shown in the image.

• 1-2=SOFT

Use Hardware Enable to keep the driver enabled all the time.

• 2-3=HARD

Images illustrating jumper settings for selecting the enable mode. The top set shows '1-2=SOFT' for software enable. The bottom set shows '2-3=HARD' for hardware enable.

LED Indicator

When Status LED (Green LED) lights, it indicates that the system is enabled.

Wiring Example

Wiring diagram illustrating the connection of the C86ACCP6 board. It shows connections from an AC Source (110/220VAC) to a 24VDC Power Supply, which then powers the board. The board is connected to a relay board and a servo motor. Signals like GND, 24V, ACORN ENABLE, ACTIVE AXIS, and STEP/DIR are shown being routed.
