Dither frequency
Name:
ConfigOutput02
This register can be used to set the frequency in 2 Hz steps.
Data type
Value
Information
USINT
0 to 255
corresponds to 0 to 510 Hz.
Dither example
Valve specification
Valve specification is 20 to 35% peak to peak of the valve current at 5 A.
This corresponds to a dither amplitude of ±5 to ±9% at 10 A.
A midrange dither amplitude of 7% at 10 A is selected. This corresponds to a setting of 70.
Dither frequency specification
40 to 70 Hz
A setting of 28 is selected.
This corresponds to a frequency of 56 Hz.
4.25.5.15.4 Communication
4.25.5.15.4.1 ABR counter
Name:
Counter01 to Counter04
These registers are 16-bit AB(R) counters.
Data type
Value
INT
-32,768 to 32,767
4.25.5.15.4.2 ABR counter latch
Name:
CounterLatch01 to CounterLatch04
When a latch event occurs, the current counter values are saved in these registers. For additional features, see
bit 5 in the respective control register.
Data type
Value
INT
-32,768 to 32,767
4.25.5.15.4.3 us_since_Trigger
Name:
usSinceTrigger01 to usSinceTrigger04
This register shows either the time in µs since the last trigger event or the average current value.
•
The "µs Since Trigger" counter cannot overrun, i.e. the counter is stopped at 2
16
-1 and retains this value
until the next time the trigger function is activated
•
If the average current is displayed in this register (bit 11 in the respective configuration register), then the
data type of µs Since Trigger in Automation Studio must be unsigned integer (UINT). The average current
value, on the other hand, is an Integer (INT). This means that negative currents are displayed between
32,769 and 65,535.
