Overview Overview Introduction The stepper motor control SMCI47-S is an extremely compact and cost-effective constant current power output stage with integrated Closed-Loop current control. Due to the great capacity and functions available, it offers designers and developers a rapid and simple method of resolving numerous drive requirements with less programming effort.
Connection and commissioning Connection diagram Introduction In order to operate a stepper motor using the stepper motor control SMCI47-S, you must carry out the wiring in accordance with the connection diagram below. Connectors X1 and X3 can be optionally used.

NanoPro. Input circuits All inputs (apart from the "Analogue In" input) are electrically isolated by optocouplers from the voltage supply of the SMCI47-S and designed for 5-24 V input signals at an input current of 10 mA. Note: The voltage must not exceed 24 V. It should drop below 2 V for safe switching off and be at least 4.5 V for safe switching on.
Technical Manual SMCI47-S V2.0 Connections and circuits Brake connection: Connector X2 Function The connector X2 is used to connect an external safety brake for the motor. This allows the holding torque and therefore the system stiffness to be increased further when necessary.
The following encoder resolutions can normally be processed by the controller: 192, 200, 256, 400, 500, 512, 1000, 1024, 2000, 2048. Recommended: Where possible, use Nanotec encoders with the order number WEDS/WEDL-5541 Xxx. If an encoder is not used, the "Disable" mode must be set in the <Error correction>...
Connections and circuits Stepper motor connection: Connector X4 General information The motor is connected to the SMCI47-S with a 4-wire cable. Twisted wire pair cables with braided shields are recommended. Danger of electrical surges Mixing up the connections can destroy the output stage! See the data sheet of the connected stepper motor.
Voltage supply connection: Connector X5 Permissible operating voltage The permissible operating voltage for the SMCI47-S stepper motor control lies between +24 and +48 V DC; it must not exceed 50 V or fall below 21 V. A charging condenser with minimum 4700 µF (10000 µF) must be provided for the operating voltage to prevent exceeding the permissible operating voltage (e.g.
CANopen (SMCI47-S-3) With the SMCI47-S, it is also possible to control the motor via CANopen. If you use the control with CANopen you can use the additional safety function of the separate logic supply: Even when the voltage supply of the SMCI47-S is interrupted,...
