SMSD-4.2CAN Stepper motor controller SMSD-4.2CAN (with CAN interface, CanOpen protocol) SMSD-4.2CAN is a stepper motor controller which is intended for operation under the control of a PLC with CANopen protocol. The CANopen protocol has a wide range of features for synchronization and synchronous operation of few controllers. The additional option of SMSD-4.2CAN - simple driver mode. For the purposes of the controller configurating, debugging and operation testing we provide the special free software CANopen Builder. • PLC connection: CAN • User PC connection: USB • Outputs: 2 digital • Inputs: 4 digital The main parameters: • Max. current per phase: 4.2 Amp • Power supply: 12 - 48 VDC • Microstepping mode: up to 1/128 Operation modes (according to protocol CANopen): • Velocity control mode - used for maintaining a specified rotation speed, acceleration and deceleration; • Position control mode - used for displacement to a specified position, with specified speed, acceleration and deceleretion parameters; • Homing mode - used for search of the zero (home) position. Phases commutation modes: The controller provides two phases commutation modes - current and voltage. The voltage mode provides smooth motion at low speeds and accurate microstepping division. Another special feature of the voltage control mode - the controller can detect if the rotor is locked. The current mode provides better torque and higher speed.
