SPA adopts only 3-digit values, the 4th digit is automatically replaced by zero.
4.3.11. Read / write specific parameter „x“ (78h)
The specific parameter „x“ comprises several sub-parameters enabling alteration of originally permanent
parameters to adapt them to new circumstances. Presently the following sub-parameter is available:
D (44h) = delaytime for minimized timeout reply of serial interface
Sub parameter: Delaytime „D“ (44h)
This parameter defines the minimum delay time (break) between the last bit received and the first bit of the
response transmitted. Delay time is in steps of 0,1 ms from 00.0 ... 60.0 ms. Default is 1.0 ms.
Example 1: Read actual delay time

Please not that the true delaytime might be prolonged. It depends on the required processing time as well as on
internal software cycles. Tolerance is approx. 8 ms.
