Wiring Basics
The MCP must be wired correctly to ensure safe and reliable operation. The diagram below illustrates a basic congurations for
wiring. An external main power cut off solution should be incorporated for safety. Power generation will occur if the motors are
moved when the system is off. Use a high current diode to create a return path to ground when the unit is switched off. Add a pre
charge resistor to avoid high inrush currents. Pre charge resistor should be 1K, 2Watt for 80VDC models. A lower resistance can be
used with lower voltages to decrease the pre-charge time.
Wiring Closed Loop Mode
The MCP supports a wide range of sensors for closed loop function. Absolute and quadrature encoders are supported along with
potentiometers and hall effect sensor.
The below illustration shows the basic wiring required for closed loop mode using quadrature encoders. Quadrature encoders are
directional. The internal MCP counter to increment in one direction and decrement in the opposite direction. When wiring encoders it
is important they are wired to match the direction of the motor. If the encoder is wired in reverse it can cause a run away condition.
Wiring Diagrams
The MCP has several different congurations depending on the type of input or output being used. See the MCP manual for additional
diagrams examples.
