Description
Valid Data
Commanded direction
$1000
W
1
Determines whether the motor should
go forward, reverse, or stop
Forward — $10
Reverse — $11
Stop — $20
Command reset
$1000
W
1
Forces the MC3PHAC to perform an
immediate reset
$30
Commanded PWM
frequency
(1)
$1000
W
1
Specifies the frequency of the
MC3PHAC PWM frequency
5.3 kHz — $41
10.6 kHz — $42
15.9 kHz — $44
21.1 kHz — $48
Measured PWM
period
$00A8
R
2
The modulus value supplied to the
PWM generator used by the
MC3PHAC — value is multiplied by
250 ns to obtain PWM period
$00BD–$05E8
Commanded PWM
polarity
(2),
(3),
(4)
$1000
W
1
Specifies the polarity of the MC3PHAC
PWM outputs. This is a write once
parameter after reset.
Example: $50 = Bottom and top PWM
outputs are positive polarity.
B + T + $50
B + T – $54
B – T + $58
B – T – $5C
Dead time
(2), (3), (4)
$0036
R/W
1
Specifies the dead time used by the
PWM generator.
Dead time = Value * 125 ns.
This is a write-once parameter.
