3-Phase AC Motor Controller
MOTOROLA
Standalone Application Example
Figure 12
shows an application example of the MC3PHAC, configured in
standalone mode. Resistor values and jumpers have been selected to provide
the following performance:
1.
2.
Base frequency of 60 Hz and positive PWM polarity (from
Table 3
)
PWM frequency resistor 3.9 k
, which implies 10.582 kHz from
Table 4
). (5v/(3.9k + 6.8k))*3.9k = 1.82 volts
Dead-time resistor = 5.1 k
, which implies 4.5
μ
s (from
Figure 9
)
Fault retry time resistor = 8.2 k
, which implies 32.8 seconds (from
Figure 10
).
Voltage boost resistor = 12 k
, which implies 25.5 percent (from
Figure 11
).
The wiper of the acceleration potentiometer is set at
2.5 V = 64 Hz/second acceleration rate (from the
Acceleration Control
description on
page 14
.) The potentiometer, in this case, could have
been a resistor divider. If a resistor divider is used in place of the
acceleration potentiometer, keep the total resistance of the two resistors
less than 10 k
. Always use 4.7k
in series with the center of the
acceleration voltage divider resistors, connected to the ACCEL (pin 27)
as shown in the application example,
Figure 12
.
Crystal/resonator capacitor values are typical values from the
manufacturer. Refer to the manufacturers data for actual values.

PC Master Software Operation
Introduction to PC Master Host Software
The MC3PHAC is compatible with Motorola’s PC master host software serial
interface protocol. Communication occurs over an on-chip UART, on the
MC3PHAC at 9600 baud to an external master device, which may be a
microcontroller that also has an integrated UART or a personal computer via a
COM port. With PC master software, an external controller can monitor and
control all aspects of the MC3PHAC operation.
When the MC3PHAC is placed in PC master software mode, all control of the
system is provided through the integrated UART, resident on the MC3PHAC.
Inputs such as START, FWD, SPEED, ACCEL, MUX_IN, and
PWMPOL_BASEFREQ have no controlling influence over operation of the
system. Even though the SPEED, START, and FWD inputs are disabled while
the system is in PC master software mode, through PC master software, it is
possible to monitor the state of those inputs.
