APEX615n Installation Guide
Resolver Connector
Connect the motor end of the resolver cable to the motor. Cables are available for SM motors
in 10 and 25 foot lengths; and for APEX Series motors in 10, 25, 50, and 100 foot lengths.
The cables have MS-type connectors on the motor end of the cable. You can also order custom
cables of any length. Call Compumotor's Customer Service Department at the phone numbers
provided on the inside front cover of this document.. Cable lengths in excess of 100 feet are
not recommended.
Plug the drive end of the cable into the APEX615n's resolver input connector. (The drive end
of the cable should already be wired to the removable 13-pin resolver connector, as shown
below. The connector can accept wires as large as 12 AWG (4 mm
2
).)
