SE C T I O N 2. 1 Mounting Recommendations The Microstepping MForce PowerDrive may be mounted two ways: end mounted or flat mounted End mount- ing will use #8 hardware, flat mounting will use standard #6 hardware. Do not exceed the recommended mount- ing torque specification.
NOTE: Ensure that proper clearance is allowed for wiring and cabling. Especially when end mounting the device. NOTE: Mounting Hardware is not supplied. Securing Power Leads and Logic Leads Some applications may require that the MForce and/or the connected motor to move with the axis motion. If this is a requirement of your application, the motor leads must be properly anchored.
Rules of Wiring • Power Supply and Motor wiring should be shielded twisted pairs, and run separately from signal- carrying wires. • A minimum of one twist per inch is recommended. • Motor wiring should be shielded twisted pairs using 20 gauge, or for distances of more than 5 feet, 18 gauge or better.
SE C T IO N 2 .2 Choosing a Power Supply for Your MForce PowerDrive When choosing a power supply for your MForce PowerDrive there are performance and sizing issues that must be addressed. An undersized power supply can lead to poor performance and even possible damage to the device, which can be both time consum- ing and expensive.
DC Power Supply Recommendations The power requirements for the Microstepping MForce PowerDrive are: Recommended IMS Power Supplies IMS unregulated linear and unregulated switching power supplies are the best fit for IMS drive products. Output Voltage ...+12 to +75 VDC (Includes Back EMF) Current (max.

SE C T IO N 2 .3 Selecting a Motor When selecting a stepper motor for your application, there are several factors that need to be taken into consider- ation: How will the motor be coupled to the load? How much torque is required to move the load? ...
NOTE: In calculating the Actual Inductance maximum phase Seen By the Driver inductance, the minimum supply output Specified Per Phase voltage should be used when using an unregulated supply. The per phase winding inductance specified may be different than the per phase inductance seen by your MForce PowerDrive driver depending on the wiring configuration used.

6 Lead Motors Like 8 lead stepping motors, 6 lead motors have two configurations available for high speed or high torque operation. The higher speed configuration, or half coil, is so described because it uses one half of the motor’s inductor windings. The higher torque configuration, or full coil, uses the full windings of the phases.
4 Lead Motors Recommended Motor Cabling As with the power supply wiring, motor wiring should be run separately from logic wiring to minimize noise coupled onto the logic signals. Motor cabling exceeding 1’ in length should be shielded twisted pairs to reduce the transmission of EMI (Electromagnetic Interference) which can lead to rough motor operation and poor system performance.
Example B: Motor Cabling Greater Than 50 Feet Common Mode Line Filters (2x) 0.5 MH MForce PowerDrive Phase Outputs Shield to Earth Ground on Supply End Only * 0.5 MH is a typical starting point for the Common Mode Line Filters. By increasing or decreasing the value of L you can set the drain current to a minimum to meet your application’s requirements.
SE C T IO N 2 .4 Optically Isolated Logic Inputs The Microstepping MForce PowerDrive has three optically isolated logic inputs which are located on connector P1. These inputs are isolated to minimize or eliminate electrical noise coupled onto the drive control signals. Each input is internally pulled-up to the level of the optocoupler supply and may be connected to sinking or +5 to +24 VDC sourcing outputs on a controller or PLC.
and sourcing configurations, the driver output circuitry will be disabled. Please note that the internal sine/cosine position generator will continue to increment or decrement as long as step clock pluses are being received by the Microstepping MForce PowerDrive. Clock Inputs The Microstepping MForce PowerDrive features the ability to configure the clock inputs based upon how the user will desire to control the drive.

NOTE: When Optocoupler Reference connecting the Optocoupler Supply, it is recommended The Microstepping MForce PowerDrive Logic Inputs are optically isolated to prevent electrical noise being coupled that you do not use MForce into the inputs and causing erratic operation. Power Ground as Ground as this will defeat the optical isolation.

Microstep Resolution Holding Current MSEL (Microstep Resolution Selection) The Microstepping MForce PowerDrive features 20 microstep resolutions. This setting specifies the number of microsteps per step the motor will move. The MForce PowerDrive uses a 200 step (1.8°) stepping motor which at the highest (default) resolution of 256 will yield 51,200 steps per revolution of the motor shaft.
HCDT (Hold Current Delay Time) The HCDT Motor Hold Current Delay sets time in milliseconds for the Run Current to switch to Hold Current when motion is complete. When motion is complete, the Microstepping MForce PowerDrive will reduce the current in the windings of the motor to the percentage specified by MHC when the specified time elapses.
Screen 2: I/O Settings Configuration Screen The I/O Settings screen may be accessed by clicking View > IO Settings on the menu bar. This screen is used to configure the Input Clock type, the filtering and the Active High/Low State of the Enable Input. Input Clock Type The Input Clock Type translates the specified pulse source that the motor will use as a reference for establishing stepping resolution based on the frequency.
IMS Part Number/Serial Number Screen The IMS Part Number and Serial Number screen is accessed by clicking "View > Part and Serial Numbers". This screen is read-only and will display the part and serial number, as well as the fault code if existing. IMS may require this information if calling the factory for support.

PWM Control Bits Example PWM Settings By Motor Specifications Figure 2.6.16: PWM Control Bits Bit 7 – QUIET This bit changes PWM operation. When quiet is set, the bridge logic does not enter the reverse measure period, therefore there are fewer transitions. The bridge is disabled during zero cross. This mode is used at rest or when moving very slowly.
SE C T IO N 2 .7 The MForce can be configured and operated through the end-user's SPI interface without using the IMS SPI Mo- tor Interface software and optional parameter setup cable. An example of when this might be used is in cases where the machine design requires parameter settings to be changed on-the-fly by a software program or multiple system Microstepping MForce PowerDrive units parameter states being written/read.

IMS SPI Interface Software communicates to the Parameter Setup Cable through the PC's USB port.
Installation Procedure for the MD-CC300-000 These Installation procedures are written for Microsoft Windows XP Service Pack 2. Users with earlier versions of Windows please see the alternate installation instructions at the IMS web site (http://www.imshome.com). The installation of the MD-CC300-000 requires the installation of two sets of drivers: Therefore the Hardware Update wizard will run twice during the installation process.
