General Description

The MBC10P31 is a low-cost single axis step motor driver integrated with a programmable pulse genera-

tor. The MBC10P31 microstep driver/pulse generator has an output current capability of 1.5A minimum

to 10.0A maximum (peak rating). The MBC10P31 driver operates with a DC voltage of 20VDC to 80VDC.

The MBC10P31’s internal controller can store two different programmable motion proﬁ les. The MBC10P31

also has directional soft and hard limit switch inputs, a busy output and a clock output that can be used for

daisy chaining drivers together. The MBC10P31 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 MBC10P31 has a ﬁ xed step resolution of 2000 steps/revolution for a 1.8°

stepper motor. The bipolar drive conﬁ guration handles 4, 6, and 8 lead step motors and is also equipped

with over current protection. The MBC10P31 communicates via USB communication. The easy to use

Windows software, SMPG-SMSI Software, is used to directly set up the two different motion proﬁ les.

Motion Proﬁ les and Running the Indexer

The programmable pulse generator has the ability to store two different motion proﬁ les. The

proﬁ les include a base speed (starting speed), a maximum speeds (running speed) and an ac-

celeration/deceleration. The base speed has a range of 1-5000Hz, the maximum speed has a

range of 1 Hz-50kHz and the acceleration/deceleration has a range of 100 to 9,999,999 steps/sec

There are “two ways” to get the unit to index: Examples are shown on the next page.

1. The ﬁ rst way is to directly control it from the computer with the software provided. Once

the motion proﬁ les have been set, the unit is ready to run. From the software, the user can

select which proﬁ 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 run input. When the run input is

activated, it looks at the max1\max2 input and selects from memory the speed proﬁ le that was

selected. To stop motion, release the run input. When this input is release, the deceleration

option will then either ramp down to base speed and stop or just hard stop. If a soft+ or soft

limit switch is activated when the Run input is active, the pulse generator will ramp down to

base speed and keep running. If a hard+ or hard- limit switch is activated when the run input

is active, the motor will stop immediately.
