CRP850-00E Breakout Board

CRP850-00E Break-out-Board
Listed belowon the following pages are descriptions and port/pin assignments.

Future Signal Inputs: The signal inputs on the CRP850-00E board are designed for NPN signals, which close signal to ground. The input signal terminals provide ports for direct wiring of limit switches, touch plate, and auxiliary signals.

Replicated Outputs: These are 5V digital outputs which can be used to drive relays with 5V coils or 5V logic level devices. They are replicates of the spindle relay and two output relays (Relay #1 and Relay #2). Note, these outputs are not relays themselves. The same signals (for Relay #1 and Relay #2) are replicated through the CRP860-00E I/O port, which goes out to the CRP860-00E board and are normally tied to solid state relays used for controlling AC loads.

Motor 6 Outputs: These outputs can be used with an additional motor driver to control a sixth motor.

5V IN: The CRP850-00E board can be powered either by 5V through this port, or via pin 26 on port 1. In most CRP800 applications, this port is not used, as 5V is passed through to the CRP850-00E board on pin 26 from the Ethernet Smoothstepper.

Motor Enable: When this terminal is jumpered, the CRP850-00E board will place a 5V potential across the motor enable terminals on all 5 motor driver connectors, disabling the motors. Typically, a mechanical switch is connected to these terminals. When the switch is closed, the motors are disabled so that the machine can be manually positioned, and motors can be safely plugged and unplugged from the system without powering down the entire controller.

Spindle Relay: These terminals provide contacts for a small dry contact relay useful for sending an on/off signal to an external VFD, typically for a forward/stop command. This signal is wired into pins 7 and 8 on the SP/THC connector in CRP800 controllers.

PWM Signal: These terminals provide a digital 0-5 signal designed to be used for speed control via PWM. This same signal (output 1 on port 2) is also routed through analog circuitry on the board to produce a 0-10V analog output.

Spindle Analog Control Signal: These terminals provide a 0-10V analog output typically used for speed control on an external VFD. This signal is wired to pins 9 and 10 on the SP/THC connector in CRP800 controllers.

12V IN: The CRP850-00E requires 12V power, both to power the optical isolators connected to all input signals, and to provide a voltage that is regulated to 0-10V for the Spindle Analog Control Signal.

Fault Signal: This input signal terminal is specifically designed to read a fault from an external VFD, typically from thermal overload or a disconnected spindle power cable.
