8.1 Motor Connection
The following chapter describes how to wire different types of two-phase stepper motors.
The stepper motor power stages may be connected to stepper motors with 1.1 to 15.4
A
phase current.
peak
The stepper motor winding resistance should be less than 10 ohm for full power.
The winding inductance of one phase should not be lower than 0.5 mH.
Stepper motors with eight leads can be connected with the windings wired in parallel (1) or
series (2).
For 6-lead stepper motors, wiring scheme (3) with series windings is recommended.
If wiring scheme (3) cannot be used because of the motor construction, the motor may be
operated with only two of the four windings energised according to wiring scheme (5).

Damage of the power stage!
5-lead stepper motors must not be connected to the MSX
Both 5-lead stepper motor and MSD2
power stage is also designed for operating in a 19" sub rack!
