Pololu high-power motor driver 24v23 cs


















This board also features a current-sensing circuit that measures bidirectional motor current with a magnitude up to 30 A and outputs an analog voltage.

Integrated detection of various short-circuit conditions protects against common causes of catastrophic failure; however, please note that the board does not include reverse power protection or any over-current or over-temperature protection. We recommend you use the integrated current sensor to keep the driver from delivering more current than it can safely handle. The motor and motor power connections are on one side of the board, and the control connections 5V logic are on the other side.

Such installations are compact but might limit heat sinking options; also, depending on the power supply quality and motor characteristics, a larger capacitor might be required. Warning: Take proper safety precautions when using high-power electronics. Make sure you know what you are doing when using high voltages or currents! During normal operation, this product can get hot enough to burn you. Take care when handling this product or other components connected to it.

The logic connections are designed to interface with 5V systems 5. The RESET pin, when held low, puts the driver into a low-power sleep mode and clears any latched fault flags.

The board also provides a regulated 5V pin which can provide a few milliamps this is typically insufficient for a whole control circuit but can be useful as a reference or for very low-power microcontrollers. If the 5V output pin is used to power VCS, it should not be used for any other purpose as the current sensor will draw close to the limit of the current the 5V pin can supply.

It can be shorted to VCS to power the current sensor. This output should not be connected to other external power supply lines. VCS Connect 5 V to this pin to power the current sensor. GND Ground connection for logic and motor power supplies. OUTA A motor output pin. OUTB B motor output pin. See the? See table below for details.

A pin straight breakaway male header, two uF capacitors, and two 2-pin 5mm terminal blocks are included with each motor driver. Note: The terminals blocks are only rated for 15 A; for higher power applications, use thick wires soldered directly to the board.

The four mounting holes are intended to be used with 2 screws not included. Pololu high-power motor driver CS with included hardware. Pololu high-power motor driver CS in a breadboard. The motor driver supports PWM frequencies as high as 40 kHz, though higher frequencies result in higher switching losses in the motor driver. Also, the driver has a dead time when the outputs are not driven of approximately 3 us per cycle, so high duty cycles become unavailable at high frequencies.

The motor driver can tolerate peak currents in excess of A. The peak current ratings are for quick transients e. The main limitation comes from heating and power dissipation; therefore, at high currents, the motor driver will be extremely hot, and performance can be improved by adding heat sinks or otherwise cooling the board.

We recommend you use the current-sense output CS to monitor your current draw if your application will put the driver close to its limits of operation. The motor driver can detect three different fault states, which are reported on the FF1 and FF2 pins. The detectable faults are short circuits on the output, under-voltage, and over-temperature.

A short-circuit fault is latched, meaning the outputs will stay off and the fault flag will stay high, until the board is reset RESET brought low. The under-voltage fault disables outputs but is not latched.

The over-temperature fault provides a weak indication of the board being too hot, but it does not directly indicate the temperature of the MOSFETs, which are usually the first components to overheat. The fault flag operation is summarized below. There are four versions of the G2 high-power motor driver, which all share compatible pinouts. The following table provides a comparison of the G2 drivers:.

Note: As an alternative to these motor drivers, our Simple Motor Controllers have similar power characteristics and offer high-level interfaces e. Using the Motor Driver Connections The motor and motor power connections are on one side of the board, and the control connections 5V logic are on the other side.

Pololu high-power motor driver CS in a breadboard. The closed-loop system uses three Pololu 18v15 high-power motor drivers as PWM amplifiers to power the magnetic coils that keep the module floating beneath the metal plate. By Meindert Norg, August, February, update: the Tripod Floater is now wireless! Version 2. This is the main 5. This regulated 5V output provides a few milliamps. Connect 5 V to this pin to power the current sensor. Ground connection for logic and motor power supplies.

Fault flag 1 indicator: FF1 goes high when certain faults have occurred. Although this motor controller has many more features than competing products, a free configuration utility for Windows and Linux simplifies initial setup of the device and allows for in-system testing and monitoring of the controller via USB.

Simple High-Power Motor Controller 18v25 or 24v23 simplified connection diagram. This video demonstrates the versatility of the Simple Motor Controller by showing how it can be controlled directly from the analog output of a Sharp analog distance sensor—there is no intermediate control board and no programming involved. For more information on this example, including the SMC settings file and a list of parts used, see our blog post about the demo.

The connector-free version allows flexibility in choice of connectors and placement of the power capacitor e.

Note: The power capacitor has a significant effect on performance; the included capacitor is the minimum size recommended, and bigger ones can be added if there is space. A bigger capacitor might be required if the power supply is poor or far more than about a foot from the controller. Warning: Take proper safety precautions when using high-power electronics. Make sure you know what you are doing when using high voltages or currents! During normal operation, this product can get hot enough to burn you.

Take care when handling this product or other components connected to it.
