MSP Integrated Stepper Drive

Drive, control, and communication are in one unit. Connect power, the motor, and an Ethernet cable, and the axis can move.
Models: MSP20, MSP28, MSP35, MSP42, MSP57, MSP60, and MSP86.

Single-axis connection

Single-axis system wiring of the MSP20–86 integrated stepper drive — The MSP controller runs motion for that axis and connects DC 24–48V, the two-phase stepper, the home sensor, and the positive and negative limits.

Quick check

Fits: A two-phase hybrid stepper in frame 20–86, when software, motion control, and the drive should sit in the same controller.

Confirm: Frame size, rated current, open-loop or closed-loop, brake, and cable length. Above frame 86, or a non-standard drive condition, check MSP1001 first.

One Ethernet daisy chain

Several MSP20–86 units daisy-chained in order over Ethernet — Each controller is one axis. Units in the same group are connected in order and separated by station address.

Several network groups

A network switch joining several MSP20–86 stepper daisy chains — When you need more than one daisy chain, a network switch groups them. Axis count and the network plan are confirmed per project.

Controller interfaces

Power, motor, encoder, brake, sensors, I/O, and network on MSP20–86 — The interface drawing is for orientation. Build from the silkscreen, the terminal table below, and the drawing supplied with the unit.

Where it sits

The MSP integrated stepper drive puts the motion controller, the drive, and protocol handling in one module, and it connects directly to a two-phase hybrid stepper. The usual layout does not add an external PLC, a motion card, or a repeated pulse harness. The hardware segment is written MSPXXX-[O/C]-[SC]-[cable]: XXX is replaced with frame 20, 28, 35, 42, 57, 60, or 86; open-loop is O, closed-loop is C, and a brake option is SC. The full XMSP configuration code also prefixes the selected XMatrix software function.

Direct connection to a two-phase hybrid stepper, frame sizes 20–86.
Open-loop or closed-loop. Closed-loop uses an optical encoder and samples position every 50 µs.
Brake control output (open-collector, external 24 V relay).

Troubleshooting

Symptom	Check first
No response at power-up, lamps off	Is the supply DC 24–48V? Are V+ and GND reversed? Is the supply large enough?
Motor does not turn, and it makes noise	Phase order A+ / A− / B+ / B−; does the current setting match the motor rated current? Is microstepping left at Default?
Lost steps, position is off	Is acceleration too high? Is the current setting low? For an open-loop axis, consider closed-loop (set SW8 off)
The host cannot connect	Is the Ethernet link a direct cable or the same subnet? Install WinPcap first. On a daisy chain, do station addresses start at 0?
Connected, but the move does not run	Has the axis been homed? Is a limit active? Is maximum travel 0? Is the device in alarm?
Limit or home is not recognized	NPN sensor wiring and supply; is the flag in the slot? Does the signal polarity match the parameter?

Check order: Supply → wiring → current and microstepping → network and station address → home and limits → software parameters and device status. Confirm each layer before the next.

First run

Connect DC 24–48V
Connect the stepper phases (A+ / A− / B+ / B−)
Plug in Ethernet, to the host or to the next unit in the chain
Open the XMatrix mode or interface you selected (Online / Command / DMX512 …)
Run the first move and confirm the motor turns
