Product Upgrade on New RoHS Compliant Driver Boards
IMD23 or 23DE units shipped after August 31, 2007 or later have the new RoHS compliant
driver boards.
During this change, the product was upgraded with several changes. No jumpers are
available on the IMD23 unit for changing step resolution or damping modes. Instead, all
settings are changed via a New Configuration Module board, which is separate from the
IMD23 or DE unit.
The Configuration Module allows users to change step resolution, run current, hold current,
damping modes, choices of reading the step and direction signals on the rising or falling
edge, and a choice of disabling the unit with no power or with limited holding current. The
configuration module is sold separately and can be purchased under RMS part
number: ACC-02.
Other changes to the unit include:
• 12 to 48VDC (old revisions handled 15 to 48VDC)
• Default step resolution setting of 8x microstepping (old revision was 256x
microstepping)
Please proceed to Section 7, Page 13, on how to use the configuration module.
