• Stepper Motor Interface:

 1 MHz Maximum Output Frequency

 Step Output

 Direction Output

 Drive Enable Output

 Drive Fault Input

• Quadrature Encoder Interface:

 4,000,000 counts/second Maximum Encoder Rate

 A and B Inputs

 Index Input with High-speed 63hs Position Latch

• Additional Inputs:

 Extend (CW) Travel Limit Input

 Retract (CCW) Travel Limit Input

 Home Input with High-speed 50µs Position Latch

• Status LED

• Digital Noise Filters on All Inputs

• All Discrete Inputs are Isolated

• Control in Open or Closed Loop (with or without quadrature interface)

Step and Direction Outputs

Each axis has two outputs for controlling the stepper motor movement. These are the Step and

Direction signals that connect to the stepper drive. The Step signal carries a series of pulses that

tell the drive how many steps (or microsteps) the motor should move. The Direction signal

controls the direction the motor moves. Both of these signals are generated by differential line

drivers.

Drive Enable Output

This output to the drive allows the RMC to turn off the drive using the Amp Enable/Disable

command. The enable output (labeled ENABLE + and -) is a solid state relay that is closed when

enabled or active.

Vcc Output

This is a nominal 5 V output that can be used in conjunction with the Step, Direction, and Enable

outputs to interface drives that require a positive common input. See Stepper Wiring for details.

Note: DO NOT use this output to power encoders.
