General Description
The MBC10SI1 is a low cost single axis step motor driver integrated with a programmable simple
indexer. The MBC10SI1 microstep driver/pulse generator has an output current capability of 1.5A
minimum to 10.0A maximum (peak rating). The MBC10SI1 driver operates with a DC voltage of
20VDC to 80VDC. The MBC10SI1’s internal controller has two different programmable motion
pro les. The MBC10SI1 also has directional soft and hard limit switch inputs, a busy output and
a complete output letting the user know when an inded is nished. The MBC10SI1 driver features
direction control and motor current On/Off capabilities. The “Reduce Current Enabled” feature
automatically reduces motor current to 50% of the set value. The driver has built in features to
indicate power on (green LED), running (yellow LED) and error conditions (red LED). The MBC-
10SI1 has a xed step resolution of 2000 steps/revolution for a 1.8° stepper motor. The bipolar
drive con guration handles 4, 6, and 8 lead step motors and is also equipped with over current
protection. The MBC10SI1 communicates via USB communication. The easy to use Windows
software, SMPG-SMSI Software, is used to directly set up the two different motion pro les.

Motion Pro les and Running the Indexer
The programmable simple indexer has the ability to store up to two different motion pro les. The
pro les include a base speed (starting speed), a maximum speeds (running speed) acceleration/
deceleration, the number of steps (index) and a complete time (output signal). The base speed
has a range of 1-5000Hz, the maximum speed has a range of 1 Hz-50 kHz and the acceleration/
deceleration has a range of 100 to 9,999,999 steps/sec
2
and the index has a range of 0-8,388,607
steps and the complete time has a range of 1-1000 milliseconds.
There are “two ways” to get the unit to index: Examples are shown on the next page.
1. The rst way is to directly control it from the computer with the software provided. Once
the motion pro les have been set, the unit is ready to run. From the software, the user can
select which pro le to run and then click the begin motion button. If a soft limit command is
sent or a soft limit input is activated, then the unit will immediately ramp down to base speed
and stop. To stop motion immediately a hard limit command needs to be sent or a hard limit
input must be activated.
2. The second way to make the unit run is to activate the individual index input. When an
index input is activated, it selects from memory the speed pro le that was selected. If a soft
limit input is activated, then the unit will immediately ramp down to base speed and continue
running until the index has completed. To stop all motion before the index has completed a
hard limit input must be activated.
