Motor phase connectIons
The drive outputs are three-phase PWM
inverters that convert 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. Further details on motor connections
can be found on page 24.
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 af ter
startup, and for checking the motor phasing
after the amplifier has switched to sinusoidal
commutation.
Motor oVer teMp Input
The 4.99k pull-up resistor works with PTC (positive temperature
coefficient) thermistors that conform to BS 4999:Part 111:1987
(table below), or switches that open/close indicating a motor
over-temperature condition. The active level is programmable.
These inputs are programmable for other functions if not used
as Motemp inputs. And, other inputs are programmable for the
Motemp function.
