www.baldormotion.com Introduction 2.1 DSM S-Series integrated motor and driver The DSM S-Series high-torque integrated motor and driver is ideal for designers who want the simplicity of a motor with on-board electronics. The DSM allows the system designer to decide the best method of control. The drive’s integrated electronics eliminates the need to run the motor cabling through the machine, reducing the potential for problems due to electrical noise.
A “Baldor Motion Toolkit CD” is available. This contains the Baldor SPI Interface software, used for communicating and configuring the DSM. This manual is intended to guide you through the installation of the DSM. The chapters should be read in sequence.
www.baldormotion.com 2.2 Receiving and inspection When you receive your DSM, there are several things you should do immediately: 1. Check the condition of the packaging and report any damage immediately to the carrier that delivered your DSM. 2. Remove the DSM from the shipping container and remove all packing material. The container and packing materials may be retained for future shipment.

www.baldormotion.com Input / Output 4.1 Introduction This section describes the input and output connections of the DSM. Logic level cables must not run parallel to power cables. Power cables will introduce noise into the logic level cables and make the system unreliable. Logic level cables must be shielded to reduce the chance of induced noise.
www.baldormotion.com 4.2 Motor power input The DSM requires an unregulated DC power supply. The power supply current will depend upon voltage and load, but will not exceed 2 A (DSMS17 / DSMS23) or 4 A (DSMS34). Location Flying leads (red and black), ‘P’ connector Input voltage +12 to +48 VDC (DSMS17) range...
www.baldormotion.com 4.2.1 Wire sizes Table 1 describes the wire sizes to provide optimal protection against EMI and RFI. Correct wire size is determined by the current requirement and the cable length. The actual cable type, wire gauge, shield type and filtering devices used are dependent on the customer’s application and system.
www.baldormotion.com 4.3 Logic inputs The DSM has three optically isolated logic inputs. These inputs are isolated to minimize or eliminate electrical noise coupled onto the drive control signals, and are over-voltage protected. The inputs may be configured as either sinking inputs or sourcing inputs (model dependent, see section 4.3.3), with the Optocoupler Reference (white) lead as the reference.
www.baldormotion.com closed) will cause the driver output circuitry to be disabled. Note that the internal sine/cosine position generator will continue to increment or decrement as long as step clock pulses are being received by the DSM. The enable input is not synchronized to any other input and may be changed at any time.
www.baldormotion.com 4.3.3 Sinking / sourcing input configuration All DSMS17, 23 and 34 models can be wired to create sinking inputs, where a reference voltage between +5 and +24 VDC is connected to the Optocoupler Reference (white) lead. The isolated inputs are then interfaced to a sinking output (which utilizes the same supply as the opto coupler reference input) such as a switch, open collector, or PLC output.
