MOTOR CONNECTIONS (CONT'D)
MoToR PHASE ConnECTIonS
The drive output is a three-phase PWM inverter that converts the DC buss voltage
(+HV) into three sinusoidal voltage waveforms that drive the motor phase-coils.
Cable should be sized for the continuous current rating of the motor. Motor cabling
should use twisted, shielded conductors for CE compliance, and to minimize PWM
noise coupling into other circuits. The motor cable shield should connect to motor
frame and the drive frame ground terminal (J2-1) for best results.
DIGITAL HALL SIGNALS
Hall signals are single-ended signals that provide absolute feedback within one
electrical cycle of the motor. There are three of them (U, V, & W) and they may be
sourced by magnetic sensors in the motor, or by encoders that have Hall tracks as
part of the encoder disc. They typically operate at much lower frequencies than the
motor encoder signals, and are used for commutation-initialization after startup,
and for checking the motor phasing after the amplifer has switched to sinusoidal
commutation.

MoToR TEMPERATURE SEnSoR

Digital input [In15] Motemp, is for use with a motor overtemperature switch or
sensor. The active level of the input, Vset, is programmable generate an over-
temperature fault if the input voltage is <Vset, or >Vset.
BRAkE oUTPUT [oUT4]
This output is an open-drain MOSFET with an internal flyback diode connected to
the +24 Vdc input. It can sink up to 1A from a motor brake connected to the +24
Vdc supply. The operation of the brake is programmable with CME 2. It can also
be programmed as a general-purpose digital output.
