Motor Power Wiring - Emerson Control Techniques EN Series Installation Manual

EN Drive Installation Manual
As shown in Figure 13, the auxiliary logic power connector is accessed through a plastic
punch-out tab located on top of the drive that reads "BUS/AUX". The auxiliary logic power
for each EN drive must be individually transformer isolated from the AC supply. The voltage
range is 127 to 373 VDC, at 21 Watts. This can be accomplished by isolating, rectifying and
filtering 90 to 264 VAC.
System
EN Drive Only
EN Drive with FM Module
Control Techniques offers Auxiliary Logic Power Supplies (models ALP-130 and -430) that
supply enough power for one EN drive with an FM module and four EN drives with FM
module's respectively. See the "Options and Accessories" section for more information.

Do not connect AC power directly into the auxiliary logic connector. You must wire this
connection correctly with transformer isolated 127 to 373 VDC power. Failure to do so
can cause death, serious injury or equipment damage. Also, use caution when removing
the plastic punch-out tab. AC power must be disconnected for at least 30 seconds before
removing the tab.

Motor Power Wiring

MG and NT Motors are equipped with up to three male MS (Military Standard) connectors,
one for stator connections, one for encoder connections and one for the brake (if so equipped).
Stator connections from the drive to the motor are made with the CMDS or CMMS cable have
a female MS style connector on the motor end and four individual wires and shield that
connect to the motor power connector on the bottom of the drive.
Note
The motor ground wire and shields must be run all the way back to the amplifier terminal
and must not be connected to any other conductor, shield or ground.
