When this circuit is active, the Encoder Output connector can be used for Hall effect sensor
inputs. The APEX615n uses the Hall sensor information to determine rotor position, so that
it can commutate the motor correctly.
With this circuit turned off, the APEX615n uses resolver inputs to determine rotor position.
It derives encoder signals from the resolver inputs, and sends the encoder signals out through
the Encoder Output connector, as described in the previous section.
Resolver Connector
Jumpers When in
Hall Effect Mode
When using the APEX615n in Hall effect mode, Compumotor recommends installing jumper
wires on the resolver connector as shown below. Also use the SFB1 command in your start-
up program to select an external encoder as your feedback source. Direct questions on this
topic to the Compumotor Applications Department at the phone numbers provided on the
inside front cover of this document.
