MCP26x Dual Channel Motor Controller Data Sheet Interface The MCP260 utilizes a DB15 female connector, Molex 6 pin connector and a 2 pin JST connector. The following tables list the pins and their available functions. All digital input pins are 15V tolerant. Digital output pins are low side driving with up to 3Amp at 40VDC. The CAN interface and RS232 pins are duplexed. When a duplex function is used the other is set to a high Z state.
MCP26x Dual Channel Motor Controller Data Sheet Encoders The MCP260A supports dual quadrature encoders with up to 40 million pulses per second. In addition, a wide range of sensor inputs including potentiometers and absolute encoders are supported. The encoder pins are not exclusive to supporting encoders and have several functions available. The encoder inputs were put on a separate connector for wiring convenience.
MCP26x Dual Channel Motor Controller Data Sheet Logic Battery The MCP supports an optional logic battery. Under heavy loads the main power can dip potentially causing brown outs. The separate logic battery will alleviate this problem. In addition a logic battery should be utilized to avoid uncontrolled behavior when the main battery power becomes low. The logic battery maximum input voltage is 12VDC with a minimum input voltage of 6VDC.
MCP26x Dual Channel Motor Controller Data Sheet Important Notices The following information is required for safe and reliable operation. It is up to the user to ensure the following criteria is met. Several external factors can influence how the MCP operates. Following basic safety procedures can prevent dangerous situations. Warnings The following guidelines should be followed when using the MCP or damage will occur. There are several factors that will affect the operation of the MCP. 1. 2. 3. 4.
MCP26x Dual Channel Motor Controller Data Sheet Wiring Basics The MCP must be wired correctly to ensure safe and reliable operation. The diagram below illustrates a basic configurations 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.
MCP26x Dual Channel Motor Controller Data Sheet Bridged Channel Mode The MCPs dual channels can be bridge to run as one channel effectively doubling its current capability for one motor. Damage will result if the MCP is not set to single channel mode before wiring. Download and install IonMotion PC utility. Connect the MCP to the computer using an available USB port. Run IonMotion and in general settings check the option to bridge channels.
MCP26x Dual Channel Motor Controller Data Sheet Status and Error LEDs The MCP has three LEDs. Two status LEDs named STAT1 and STAT2 and an error LED named ERR. When MCP is first powered up all 3 LEDs should flash briefly to indicate all LEDs are functional. The LEDs will behave differently depending on the mode. During normal operation the status 1 LED will remain on continuously or blink when data is received in RC Mode or Serial Modes. The status 2 LED will light when either drive stage is active.
MCP26x Dual Channel Motor Controller Data Sheet Firmware Update LED State If all three LEDs begin to cycle on and off after powering on, the MCP has successfully been set to install new firmware. Use Basicmicro Motion Studio on a Windows PC to install the new firmware to clear this state. Automatic Battery Detection on Startup If the automatic battery detection mode is enabled the Stat2 LED will blink to indicate the detected battery type. Each blink indicates the number of LIPO cells detected.
MCP26x Dual Channel Motor Controller Data Sheet Bridged Channel Mode The MCPs dual channels can be bridge to run as one channel effectively doubling its current capability for one motor. Damage will result if the MCP is not set to bridge channel mode before wiring. Download and install Basicmicro Motion Studio PC utility. Connect the MCP to the computer using an available USB port. Launch Motion Studio and in general settings check the option to combine channels.
