Components
Motor
The motor is a two-phase brushless stepper motor. The step angle of the motor is 1.8°.
Electronics Housing
The electronics system is comprised of control electronics and the power stage.
The drive system is controlled by a CANopen master sending Service Data Object (SDO) and
Process Data Object (PDO) data over CAN bus 2.0b active.
Interfaces
DC Power Interface
The DC Power Interface connection supplies VDC and AUX power connections for the drive via
a 4-position M12 (male, B-coded) connector (P1). The VDC connection provides power to the
control electronics and power stage. The 12 to 24V Aux-Power input supplies power to logic
circuits in the event of main supply loss.
NOTE:
The ground connections of all interfaces are galvanically connected. For more
information on ground connections and protection against reverse polarity, see “Ground (Earth)
