PD2-N41 - Plug & Drive High-Pole DC Servo Motor for RS485/CANopen - NEMA 17

Technical Data

A high-pole DC servo motor (stepper motor) in size 42 (Nema 17) and with a 50-Ncm holding torque. In this integrated Plug & Drive motor, the entire electronics are contained within the housing. In addition to a powerful motor controller, this motor also contains a magnetic single-turn absolute encoder. The field-oriented control (closed loop) enables high positioning accuracy without step loss and with dynamics, energy-efficient operation and low motor heating.

For parameterization, Nanotec provides the free NanoPro (RS485) and NanoCAN (CANopen) Windows software. In a distributed environment, the NanoJ Easy software, which is also free of charge, can be used to developed autonomous application programs that are independent of the master PLC.

Attention: When using laptops connected to the line supply, detach the power cable before connecting the USB cable as there is a 115VAC voltage present from the power supply while the battery is being charged. When the unit is plugged in, the DC current would otherwise run via the USB connection and destroy the motor controller. Repair would no longer be possible.

Suppression circuit for overcoupling of 24-V control signals

Depending on the cable type, routing and length, an overcoupling onto the neighboring control line may occur with 24-V control signals. In motor controllers with wide range inputs (5–24V), this can cause a second input that is not activated to be recognized as high. To prevent this without having to change the wiring (which can be an involved process), the following suppression circuit can be provided at each input in use. Inputs that are not required can be connected directly to the motor controller ground.


Switching of a load or PLC via the outputs of the motor controller/Plug & Drive motor

The motor controllers and Plug & Drive motors have open collector outputs. To switch a load or PLC, you require a relay according to this circuit diagram. The flyback diode is required. Please note the maximum switching current or the maximum voltage of the selected motor controller. You can find this information in the respective manual.

SMCI35: A load/PLC cannot be connected with this motor controller.

The firmware update failed – no more communication

If communication is no longer possible with the motor controller or the motor after a failed firmware update, the firmware can be uploaded manually.
