Example:
^OTL 75 : Set Over temperature limit to 75 Celsius degrees.
PWMF - PWM Frequency
HexCode: 06
Description:
This parameter sets the PWM frequency of the switching output stage. It can be set from
1 kHz to 30 kHz. The frequency is entered as kHz value multiplied by 10 (e.g. 185 = 18.5
kHz). Beware that a too low frequency will create audible noise and would result in lower
performance operation.
Syntax Serial: ^PWMF nn
~PWMF
Syntax Scripting: setconfig(_PWMF, nn)
Number of Arguments: 1
Argument 1: Frequency
Type: Unsigned 16-bit
Min: 100 Max: 300
Default: 160 = 16.0kHz
Where:
nn = PWM Frequency *10
Example:
^PWMF 200 := Set PWM frequency to 20kHz
Note:
Do not change the default PWM frequency when operating brushless motors in sinusoi-
dal mode.
SCPR - SSI Sensor CPR Value
HexCode: CE
Description:
This parameter will set the counts per revolution of the SSI Sensor that is attached to the
controller. The CPR is the number of counts that is issued by the SSI Sensor when making
a full turn. Entering a negative number will invert the counter and the measured speed
polarity.
Syntax Serial: ^SCPR cc nn
~SCPR [cc]
Syntax Scripting: setconfig(_SCPR, cc, nn)
Number of Arguments: 2
