Chapter 6 Connecting the Stage
Hall Effect Circuit Use the following information to connect the Hall Effect circuit to your servo
drive.
• Input power: 5 … 24 V DC, 10 mA maximum
• Output: NPN, Open Collector, 10 mA maximum
Motor and Hall Phasing and
Sequence Consult drive manual or supplier for wiring instructions for your drive. Motor
wiring is phase and commutation sensitive. Motor Phasing Diagram
shows the
standard phase and sequence relationship of the motor when phased in the
positive direction. The Hall signals are used by a compatible three-phase-
brushless servo drive to perform electronic commutation. Two types of servo
drive Hall-based commutation techniques are possible, Trapezoidal Hall Mode
and Encoder Software Mode with Hall startup. For optimal commutation and
force generation, the selected servo drive must be compatible with the motor
phasing and be wired correctly.
• Observe maximum applied voltage specification.
• Consult drive manual or supplier for drive wiring instructions. Wiring is
phase and commutation sensitive.
• Terminate per drive manual instructions.
• Hall Signals, 120
o
Spacing, Open Collector Transistor 24V maximum.
• Refer to CHPS-Series Stage Connector Data starting on
page 33 for
termination options, pin, and wire designations.
