Customer-supplied 24V DC Power Supply Notes (Kinetix MMA motors)
• Kinetix MMA brakes may require a customer-supplied 400… 480V AC
single-phase supply, rather than a 24V DC supply. However, the brake
current ratings required by Kinetix MMA motors are higher than the
contact rating of the GPR connector. Therefore, if using an Kinetix MMA
motor with a brake, it is recommended that a customer-supplied, external
interposing relay or equivalent circuit be used. See Figure 88
below.
• The contact connected to GPR1+ and GPR1- is rated 2 Amps inductive
@ 250V AC/30V DC maximum.
• See the Kinetix Motion Control Selection Guide, publication
KNX-SG001
for Kinetix MMA motor brake ratings.

Kinetix MMA Motor Blower Connections
• The radial blower connection comes from the factory wired as a star
(400…480V) three-phase configuration. A customer can choose to rewire
to the delta 230V 3-phase configuration. The star and delta connection
and motor ratings can be found on the motor name plate. See the Kinetix
MMA Asynchronous Servo Motor Installation Instructions, publication
MM-IN001
, for connection diagrams. It is not recommended to change
the wiring configuration for your blower motor.
• See the Kinetix Motion Control Selection Guide, publication
KNX-SG001
for Kinetix MMA motors blower voltage and current
specifications.
• The Kinetix MMA motor blower must be used to ensure proper motor
performance. A separate blower terminal box is provided to connect
external power to the blower. See Ta b l e 6 9
for additional information.
