  • Page 5: Overview

    Overview Overview Introduction The SMCP33 stepper motor control is an extremely compact and cost-effective constant current final 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.
  • Page 6 Technical Manual SMCP33 Overview ® With dspDrive , the motor current is controlled directly by a digital signal processor. Unlike conventional ICs, which resolve the winding current measurement and the ® target current value with only 6 or 8 bit, the new dspDrive performs the entire control with a resolution of 12 bit.
  • Page 7: Commissioning

    Provisions Commissioning of the SMCP33 stepper motor is described below. You will find the main "First Steps" here to start working rapidly with the SMCP33 if you are using the NanoPro software from a PC. You will find more detailed information in the separate NanoPro manual.

    It can be used for the rapid commissioning of four stepper motors via a pre-wired RS485 network and a PC connection. All inputs and outputs available in the SMCP33 are led to the outside via Phoenix Combicon connectors. In addition, an encoder or a brake can be connected.

  • Page 15: Brake Connection

    This resistor is also referred to as the "Brake resistor" because the energy usually arises from braking of the motor. This protects the SMCP33 against destruction from brief overvoltage. The rating and cooling of the resistor determines how long it can convert the overvoltage before it becomes too hot and is destroyed.
  • Page 16: Encoder Connection

    Stepper motor connection Connection cable The motor is connected to the SMCP33 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.
  • Page 17: Bldc Motor Connection

    Power supply connection Permissible operating voltage The permissible operating voltage of the SMCP33 stepper motor control lies within the range +12 to +48 V DC and must not exceed 50 V or undershoot 10 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.

    This network connection is set up via the RS485 port. Example: Connection to SMCP33-EVA On the SMCP33-EVA motherboard shown in Section 3.2 "SMCP33-EVA evaluation board", four stepper motors can be rapidly commissioned via a pre-wired RS485 network and a PC connection.
