PWM resolution, 15-bit + sign, minimum 10 ns Configurable dither 2x 2 inputs 24V, can be configured as AB Sink connection 1-wire connections The motor bridge module is used to control 2 DC motors with a nominal voltage of 24 to 39 VDC ±25% at a nominal current up to 3 A.
The module can be reconfigured and used in current controller mode for controlling inductive loads.
The module is also equipped with 4 digital inputs, which can be used as incremental counters.
Each motor is controlled with a full-bridge (H-bridge). This enables the motors to be moved in both directions.
