4.26.4.9.4 Configuration registers
4.26.4.9.4.1 Excitation time
Name:
ConfigOutput02
The excitation time is configured in this register.
The output is switched fully on for the time set in this register after the module is switched on. After the excitation
time expires, the module goes into PWM mode.
Data type Value Information
USINT 0 to 255 In steps of 100 µs or 1000 µs
4.26.4.9.4.2 PWM ratio
Name:
ConfigOutput03
The PWM ratio between switch-off time and period duration is set in this register (in percent).
Data type Value Information
0 Permanently switched off
1 to 99 Ratio = switch-off time / period duration (1 to 99%)
USINT
100 Permanently switched off
4.26.4.9.4.3 Module configuration
Name:
ConfigOutput04
This register is used to configure the module's general parameters.
Data type Value

4.26.4.9.4.4 Current and time differential
Name:
ConfigOutput05 to ConfigOutput20
The switching point search is configured with the parameters dI and dt in these non-cyclic registers.
•
dI - Current differential in LSB
•
dt - Time differential in 100 μs steps
For a sample configuration, see 4.26.4.9.6 "Configuring dI and dt"
