6.4 X8 Motor Connector
6.4.1 Stepper Motor Connection
Suitable stepper motor types for operation with MCC-1:

Two-phase stepper motors with 4, 6 or 8 lead wiring scheme and up to 3.5 A
Peak
phase
current

Winding resistance below 10 Ohms

Winding inductivity of one motor phase 0.5 to 10 mH

To ensure electromagnetic compatibility (EMC), all parts of the motor housing should
be conductively connected with each other.
The figure below shows the connection of a two-phase stepper motor with 4-lead wiring
scheme and parallel connected windings:
DANGER
Danger of electric arcing!
Do not plug or unplug any connector
when powered!
Fig. 16: Motor connection to X8 connector
Depending on application and stepper motor design, other wiring modes are possible, e.g.
serial connected windings. See next chap. 6.4.2.
WARNING
Power stage damage in case of faulty connection!

Before running the motor, the motor currents should be set to suitable
values! See chap. 6, Putting into service.

5-phase stepper motors must not be operated with MCC-1 controllers.
Connecting 5-phase stepper motors would result in damaging the
power stage .
i
The supply voltage value affects the setting accuracy of the motor current. In
addition the setting accuracy depends on inductance and resistance of the
motor. The current can be set less exactly, if the current value is smaller than
600 mA.
We recommend to use the linear MCC-2 LIN controller if the accuracy of the
motor current setting must be improved.
