Introduction to the MDrive17 Motion Control
Introduction to the MDrive17 Motion Control
The MDrive17 Motion Control offers the system designer a low-cost, intelligent motion controller integrated with a NEMA 17 high
torque stepping motor and a +12 to +48 VDC microstepping drive.
The MDrive17 Motion Control adds a versatile array of functions by combining a complete programmable motion controller with
our already compact and cost effective standard MDrive17, adding little cost and no increase in size. Standard offerings include four
5 to 24 volt programmable I/O points, one 10-bit 0 to 5 volt analog input, 0 to 5 MHz step clock rate, microstep resolution up to
51,200 steps per revolution and a full featured easy-to-program instruction set.
The MDrive17 Motion Control communicates using the RS-485 communications protocol, this allows for point-to-point or multi-
drop communications using one communications port. Addressing and hardware support up to 62 MDrive nodes in a system. The
communications BAUD rate is software selectable and ranges from 4.8 kbps to 115 kbps.
The MDrive17 is also available with an optional closed loop control. The closed loop configuration adds a 512 line (2048 count)
internal magnetic rotary encoder with index mark without increasing the length of the unit. Closed loop configuration adds position
maintenance, stall detection and find index mark.
Available motor configurations include: single shaft, double shaft with control knob, and long life ACME screw linear actuator.
Rotary versions are available in three stack lengths: 13, 15 & 19. Interface connections are accomplished using either a 7 position
terminal block or optional 12” flying leads.
