5.8 Connection summary - recommended system wiring
As an example, Figure 45 shows the recommended wiring necessary for the MicroFlex
e
100 to
control a motor, while conforming to the EMC requirements for ‘industrial’ environments.

Motor power U V W
Control circuit supply (fused).
Use twisted pair cable with a
ferrite sleeve (see section 3.4.8).
Motor
+24 VDC
Notes:
1) The MicroFlex
e
100 should be mounted on an earthed metal backplane.
2) Ensure cables do not obstruct airflow to the heatsink.
3) Motor represents a typical Baldor BSM motor. Linear motors may also be controlled by MicroFlex
e
100.
4) Conductive shield earth/ground clamps are not supplied.
5) The threaded holes in the top and bottom of the case are for M4 bolts no longer than 11 mm (0.43 in) in length.
6) When using single phase supplies it may be necessary to reverse the AC power filter - see section 3.4.7.2.
