MD42-o Family

42mm Stepper Motor with Controller & Driver, 0.22 – 0.70Nm, 24V, Absolute Encoder, USB/RS485/CAN

The MD42-o Family replaces PD-1140 and PD-1141 Families in our product portfolio.

The MocDrive MD42-o Family family is a mechatronic solution including a 40mm flange stepper motor, a controller board and an absolute encoder. It can be controlled via serial interface or operated in standalone mode. Power supply, external encoder, interface and I/Os can be connected with JST connectors.

With the advanced StallGuard2™ the motor load can be detected with high resolution. The outstanding CoolStep™ technology for sensorless load dependent current control allows efficient motor operation.

Using predefined TMCL high level commands like move to position or constant rotation a rapid and fast development of motion control applications is guaranteed. Communication traffic is kept very low since all time critical operations, e.g. ramp calculation are performed on board. The TMCL™ program can be stored in the on board EEPROM for stand-alone operation. The firmware of the module can be updated via the serial interface.
