Transitioning from IM483/IM805 to MForce Step/direction
When converting an application from IM483/IM805 drives to MForce Step and Direction drives, there are many considerations. These two systems have very similar stepper drive capabilities. The MForce’s current capability is listed in RMS Amps while the IM483/IM805 drives output currents were listed in Peak Amps. As a result, the MForce MicroDrive’s three amps RMS is very close to the IM483 4 amps PEAK and the MForce PowerDrive’s five amps RMS is very close the IM805’s seven amps PEAK. Another thing to keep in mind is that while the IM483/IM805 drives had short circuit protection on their phase outputs, the MForce drives do not. Both drive systems have a default of 256 microsteps per full step. The MForce MicroDrive’s heat sink should be mounted so that it conducts heat to the panel using the heat sink pad supplied with the drive. Mounting for the IM483/IM805 drives naturally connected the aluminum extrusion to the panel and a thermal pad was also sold as an option. These two systems have very different setup features and functions. For example, the IM483/IM805 drives use a resistor scheme to set both the run current and the hold current while the MForce Step and Direction drives use an SPI communications interface with a Windows GUI to make changes to these values that are stored in flash memory on the drive. The IM483/IM805 drives use a dip switch to set microstep resolution while that is also done using the Windows GUI on the MForce Step and Direction drives. Here is a listing of settable parameters for the MForce Step and Direction drives:
To summarize, application requirements should be closely examined when considering this course of action. Please feel free to contact Technical Support with any questions you may have regarding any particular application.
