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. The DSM is a small, powerful and inexpensive solution that will reduce system cost, design and assembly time for a large range of stepping motor applications.
The DSM family use a NEMA17, NEMA23 or NEMA34 1.8° high torque motor combined with a microstepping drive, and accept up to 14 resolution settings from 1/2 to 256 microsteps per step. Setup parameters can be changed ‘on-the-fly’ or downloaded and stored in non-volatile memory with the use of a simple user interface program which is provided, eliminating the need for external switches or resistors. The versatile, compact DSM is available in multiple configurations to fit various system needs.

3.1.2.4 Securing DSM cables
Some applications may require that the DSM moves with the axis motion. If this is a requirement of your application, the motor leads must be properly anchored. Secure the flying leads to the motor body using adhesive cable clamps. This will prevent flexing and tugging which can cause damage at critical connection points in the DSM electronics.
Do not bundle the logic leads together with the DSM power leads.

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. The shield needs to be grounded at the signal source to AC ground; the other end of the shield must not be connected. This allows the shield to act as adrain.
Do not connect or disconnect any wiring when power is applied! Disconnect the AC power side to power down the DC power supply. For battery operated

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).

Volta ge ripple ±10%
Input current 2 A maximum (DSMS17 / DSMS23)
4 A maximum (DSMS34)
The maximum input voltage of the DSM includes motor back EMF, power supply ripple and high line.
CAUTION
A characteristic of all motors is back EMF. Back EMF is a source of current that can push the output of a power supply beyond the maximum operating voltage of the driver. As a result, damage to the stepper driver could occur over a period of time. Care should be taken so that the back EMF does not exceed the maximum input voltage rating of the DSM.
Cable length, wire gauge and power conditioning devices play a major role in the performance of the DSM. The length of the DC power supply cable to a DSM should not exceed 15 m (50 ft). If cabling of 15 m (50 ft) or longer is required, the additional length may be gained by adding an AC power supply cable (see Figures 6 and 7). Power supply leads to the DSM need to be twisted. If more than one DSM is to be connected to the same power supply, run separate power and ground leads from the supply to each driver.

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. Always use shielded twisted pairs for AC and DC supply cables. For logic wiring (see section 4.3) AWG22 wire is recommended.

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. This allows the DSM to be interfaced to a variety of controllers.

4.3.1 Logic input descriptions
4.3.1.1 Step clock (orange flying lead)
The step clock input is where the motion clock from the control circuitry will be connected. The motor will advance one microstep in the plus or minus direction (based upon the state of the direction input) on the step clock edge that causes the opto-isolator to be active. The size of this increment or decrement will depend on the microstep resolution setting. The maximum frequency on the step clock input is 2.0 MHz, with a minimum pulse width of 400 ns.
4.3.1.2 Direction (blue flying lead)
The direction input controls the CW/CCW direction of the motor. A logic high (default, unconnected) will cause the motor to rotate in the CW direction (seen while looking at the face of the motor). A logic low on the input will cause the motor to rotate in the CCW direction. This input is synchronized to the positive going edge of the step clock input. The direction input may be connected by means of a switch.
4.3.1.3 Enable (brown flying lead)
This input can be used to enable or disable the driver output circuitry. A logic high (when the enable switch is open, see Figures 9 and 10), causes the driver outputs to be enabled and step clock pulses will cause the motor to advance. A logic low (when the input switch is
4-4 Input / Output MN1940
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.
4.3.2 Input timing
The direction input and the microstep resolution inputs are internally synchronized to the positive going edge of the step clock input. When a step clock transitions from low to high on the positive going edge, the state of the direction input and microstep resolution settings are latched. Any changes made to the direction and/or microstep resolution will occur on the rising edge of the step clock pulse following this change. Run Current and Hold Current changes are updated immediately (see section 5.2.2).

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. T o maintain isolation, the input power source should not be connected to the motor power source.

5 Operation

5.1 Introduction

The motor interface is accessed through the Baldor SPI Interface software, which is an easy to install and easy to use program used to set the DSM’s parameters. The Baldor SPI Interface is included on the Baldor Motion Toolkit CD.
5.1.1 Connecting the DSM to the PC
The DSM is connected to the PC using a standard USB port. It is recommended to use the optional CBL055-501 parameter setup cable (see section 4.4).
5.1.2 Installing the USB driver
When the parameter setup cable (CBL055-501) is connected to the PC, Windows XP will automatically detect it and display the Found New Hardware Wizard. It is now necessary to install the drivers, which are provided on the CD supplied with the cable. Alternatively, the driver files can be downloaded from www.baldormotion.com/supportme folder on the PC.
1. Choose the No, not this time option and click Next >.
2. Choose the Install from a list or specific location (Advanced) option and click Next >.
3. Check the Include this location in the search option. Click Browse and locate the drivers folder on the CD. For downloaded files, locate the temporary folder containing the extracted files. Click Next >.
4. When Windows finds the required driver files, a dialog will warn that they have not passed ‘Windows Logo testing’. This is normal for the parameter setup cable’s USB driver, so click Continue Anyway to continue with the installation.
5. When the Completing the Found New Hardware Wizard message appears, click Finish.
After a few moments, the Found New Hardware Wizard will appear a second time, ready to install the virtual COM port driver.
and placed in a temporary
5
5.1.3 Installing the virtual COM port driver
As soon as the USB driver has been installed, the PC starts to communicate with the parameter setup cable’s interface. This immediately reveals the other part of the interface’s hardware, the virtual communications port (VCP), which provides communication with the DSM motor. The VCP also requires drivers to be installed, which is why the Found New Hardware Wizard appears a second time.
1. Choose the No, not this time option and click Next >.
2. Choose the Install from a list or specific location (Advanced) option and click Next >.
3. Check the Include this location in the search option. The previously used location should already be selected, but if not click Browse and locate the required folder. Click Next >.
Operation 5-1MN1940
www.baldormotion.com
4. When Windows finds the required VCP driver files, a dialog will warn that they have not passed ‘Windows Logo testing’. This is normal for the parameter setup cable’s VCP driver, so click Continue Anyway to continue with the installation.
5. When the Completing the Found New Hardware Wizard message appears, click Finish.
A final Found New Hardware message will appear on the task bar to inform you that the hardware is now ready to use.
Note: If the MotiFlex e100 is later connected to a different USB port on the host computer,
Windows may report that it has found new hardware. Either install the driver files again for the new USB port, or connect the MotiFlex e100 to the original USB port where it will be recognized in the usual way.
5.1.4 Determining the virtual COM port number
The parameter setup cable’s virtual COM port appears as a normal COM (serial) port in Windows, and is automatically allocated a COM port number. The Baldor SPI Interface software normally auto-detects the motor regardless of the allocated COM port. If for any reason the Baldor SPI Interface software fails to auto-detect the motor (section 5.2.1), it may be necessary to manually select this COM port.
1. In Windows, right-click the My Computer icon and choose Properties.
2. Choose the Hardware tab and click Device Manager.
3. Expand the Ports (COM & LPT) item.
4. Look for the entry named Baldor USB to SPI ParameterSetup Cable (COM...). The value that appears after COM is the port number. Make a note of this number.
5.1.5 Installing Baldor SPI Interface
You will need to install the Baldor SPI Interface software to configure the DSM.
1. Insert the CD into the drive.
2. After a few seconds the setup wizard should start automatically. If the setup wizard does not appear, select Run... from the Windows Start menu and type
d:\Baldor_SPI_Interface.exe
where d represents the drive letter of the CD device.
Follow the on-screen instructions to install the software. The setup Wizard will copy the files to appropriate folders on the hard drive.

5.1.6 Starting the controller and DSM
If you have followed the instructions in the previous sections, you should have now connected power sources, inputs and outputs, and the USB cable linking the PC with the DSM. Before you apply power for the first time, it is very important to verify the following:
H Inspect all power connections for accuracy, workmanship and tightness. H Verify that all wiring conforms to applicable codes. H Check all signal wiring for accuracy.
1. Turn on the controller (e.g. NextMove ESB, if connected).
2. Turn on the motor power supply.

5.2 Baldor SPI Interface

The Baldor SPI Interface is a simple application for configuring all aspects of the DSM.
5.2.1 Starting Baldor SPI Interface
On the Windows Start menu, select Programs, BALDOR SPI Interface, BALDOR SPI Interface. The software will immediately try to establish communication with the DSM. If this step fails, the word “Disconnected” will appear in red. Check that the DSM is powered and that the cable is connected, then choose the Port menu item. Select the appropriate USB port from the list of USB/Serial port options (this is the COM port number found in Windows Device Manager - see sectio n 5.1.4).
5.2.2 Configuration parameters
These parameters may all be changed ‘on-the-fly’. To select different views, choose the View menu item.
5.2.2.1 Motion settings view
The motion settings view shows the main configuration parameters for the DSM:
Click in the boxes or use the arrow buttons to adjust values.

50 10000 256 51200
Motor Run Current (MRC)
The Motor Run Current (MRC) parameter sets the motor run current to a percentage of the full output current of the DSM driver section.
Hold Current Delay Time (HCDT)
The HCDT parameter sets the delay time between the last c lock pulse and the application of the holding current.
Motor Hold Current (MHC)
The MHC parameter sets the motor hold current as a percentage of the full output current of the driver. If the hold current is set to 0, the output circuitry of the driver section will disable when the hold current setting becomes active. Following the last step clock pulse, the hold current setting becomes active after the period specified by HCDT.
Direction Override (DIR)
The DIR parameter changes the motor direction relative to the direction input signal, adapting the direction of the DSM to operate as your system requires.
Factory button
The Factory button resets each parameter in the software to factory default values. Click Set to apply these values.
Recall! and Upgrade! menu options
The Recall! option uploads the existing parameter settings from the DSM. The Upgrade! option (if present) must not be used! It currently has no purpose and will erase the firmware on the DSM, leaving it inoperable. If you have accidentally selected the Upgrade! option, please contact Baldor customer support.
Operation 5-5MN1940

5.2.2.2 I/O settings view
The I/O settings view shows two additional parameters for the DSM:
Clock Type
The Clock Type parameter configures the step and direction inputs for the type of input signals being supplied to the motor.
H Step/Dir is the default setting. A waveform supplied to the step
input causes the motor to advance one step for each rising edge. The direction input is held either high or low to determine the direction of motion.
H Quadrature requires a pair of waveforms, such as those
typically produced by an incremental encoder. The two waveforms are at the same frequency but approximately 90° out of phase (i.e. ‘in quadrature’). One is supplied to the step input, the other to the direction input. Each edge causes the motor to
Step
Dir
Step
(CHA)
Dir
(CHB)
advance one step, with the direction being determined by the relative timing of the waveforms. For example, if the rising edge on the step input waveform is received before the rising edge on the direction input waveform, the motor will turn in one direction. If the rising edge on the direction input is received first, the motor will turn in the opposite direction.
H Up / Down requires a waveform to be supplied to either the step
input or the direction input. If the waveform is supplied to the
Step
step input, the motor will turn in one direction. If the waveform is supplied to the direction input, the motor will turn in the
Dir
opposite direction.
Clock IOF
The Clock IOF parameter sets the frequency of the clock input filter. Values in the range 50 ns to 12.9 μs (10 MHz to 38.8 kHz) are available.
