Space stepper motors
- Always remove the PTFE tubes before connecting the stepper
motor
.
- Before mounting the motor: Do not remove the PTFE tubes!
The wires can only be identified by their markings.
- Connecting the wires: Only remove the PTFE tube from the wire
being connected. Be careful not to mix up the wires. The start and
end of a winding in an 8-lead stepper motor cannot be determined
by measurement.
- Recommendation: Keep the PTFE tubes! If disconnecting the
stepper motor, the markings should be reattached.
6.2.2 Connecting the Leads
i
CAUTION
– Possible damage!
The leads of the motor:
- If the leads from stepper motor to control terminals are not shield-
ed, they should be as short as possible!
- The leads of one motor phase, see Fig. 6, should be twisted pairs,
e.g. A and B, C and D (4-lead motor).
-
The wires must not be stressed.
Provide strain relief when twist-
ing, shortening or stripping the motor leads!
The motor's strain relief needs additional security when modifying
the wires.
