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. More detailed information can be found in the separate NanoPro manual. - Page 8 Select the <Communication> tab. In the "Port" field, select the COM port to which The number of the COM the SMCP33 is connected. port to which the controller is connected can be found in the device manager of your Windows PC (System Control/System/Hardware).

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 12 Technical manual SMCP33 Connections and circuits Connection diagram Note: The connection diagram is available for download on www.nanotec.de.

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
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 HEDS/HEDL-5541 Xxx. If an encoder is not used, the "Disable" mode must be set in the <Error correction>... -
Page 17: Stepper Motor Connection
Connections and circuits 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!

Page 19: Power Supply 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. -
