Explanations
OUTPUT_VALUE You specify the duty cycle with this value.
Value range:
• Duty cycle: -27648 to 27648
D
:
If the low limit or the high limit is violated, the feedback bit ERR_OUT_VAL is set and the mini-
mum or maximum value is used.
SLOT You specify the load value with this value.
Value range:
• Period duration in μs: 100 to 85000000
D
• On delay in μs: 0 to 85000000
D
You specify whether to apply a change once or cyclically with MODE_SLOT.
Invalid values trigger setting of feedback bit ERR_LD (when MODE_SLOT = 0) or
ERR_SLOT_VAL (when MODE_SLOT = 1).
MODE_SLOT You specify whether you want to apply a change in SLOT once or cyclically with this bit.
0 means: As soon as you write the respective value in the corresponding output byte, the value
from SLOT is applied once and kept until the next change. A change of the On delay via SLOT
takes effect at the next output sequence. A change of the period duration via SLOT takes effect
at DQn.A/DQn.B with the next rising edge. After a restart of the module, the value is overwritten
with the value set in the hardware configuration.
1 means: When you write the respective value in the corresponding output byte, the current
value from SLOT in each case is applied cyclically. A change of the On delay via SLOT takes
effect at the next output sequence. A change of the period duration via SLOT takes effect at
DQn.A/DQn.B with the next rising edge.
