3-18 Basic Installation MN1942
3.5 Motor connections
MicroFlex e100 will operate with a large number of brushless servo motors. For information on
selecting Baldor servo motors please see the sales brochure BR1202, available from your local
Baldor representative. The motor must be capable of being powered by an inverter PWM output
- see section 8.1.3 for details. The motor can be connected directly to the MicroFlex e100 or
through a motor contactor (M-Contactor). The motor outputs are conditionally short-circuit proof.
Motors should ideally have a minimum inductance of 1 mH per winding; for motors with lower
inductance an output reactor may be fitted in series with the motor .
When using a Baldor motor, the parameters for managing motor overloads are configured
automatically by the Commissioning Wizard (see section 6.4.3). If they need to be changed, or
you are using an alternative motor, use the Parameters tool in Mint WorkBench (see section
6.5.2).

Figure 7 - Motor connections
Do not connect supply power to the MicroFlex e100 UVW outputs. The
MicroFlex e100 might be damaged.
The motor leads U, V and W must be connected to their corresponding U, V or W
terminal on the motor. Misconnection will result in uncontrolled motor movement.
The motor power cable must be shielded for CE compliance. The connector or gland used at the
motor must provide 360 degree shielding. The maximum recommended cable length is 30.5 m
(100 ft).
Note: For CE compliance the motor earth/ground should be connected to the drive
earth/ground.
