FAULT_REACT_MODE_00

FTP

Fault reaction mode Group 00:

0: Fault on one string, all strings of the same group are

turned off

1: Fault on one string, no action on other strings of same

Group

PHASE_DEV

(Read Only in RAM)

FTP

PWM phase shift in Responder mode: Phase Shift with

regards to SYNC_I/O synchronized clock in 15 µs steps:

000: 0 µs

001: 15 µs

010: 30 µs

...

111: 105 µs

OUT_DELAY

FTP

Enable/Disable of gradual output delay:

0: gradual delay disabled

1: gradual delay enabled

SYNC I/O_P/C

FTP

Provider/Consumer SYNC_I/O: Synchronization of PWM

frequency and phase between Provider and Consumer

Devices

1: Provider Mode selected. SYNC_I/O is input. Clock

frequency and phase signal on the SYNC_I/O line is used

to synchronize own clock

0 (default): Provider Mode selected. SYNC_I/O is output.

Device Clock frequency with scaler and phase signal is

transfered to the SYNC_I/O line

PWM_SYNC

Reset bit for internal PWM counter:

0: PWM counter running

1: PWM counter reset to zero; bit is automatically cleared

directly after reset
