4.3.9. Read / write motor system times „k“ (6Bh)
This command reads or writes the individual motor system times within the range of 00.1 s to 99.9 s.
Tolerance: ±7% at minimum time; < 1‰ at maximum time, approx. 1% at 1 s.
The following 3 parameters are available:
Loop: Waiting time at turning point during loop operation.
Trailing error: Timeout for motor signal, if shaft remains idle after the motor start signal
Clamping:
Timeout reply between enabled/active clamping or braking action
prior to motor start signal / after motor stop signal.
Example 1: Read parameter (loop = 1.0 s)

4.3.10. Read / write specific parameter „x“ (78h)
The specific parameter „x“ comprises several sub-parameters which permit alteration of originally permanent
parameters to adapt them to a new situation. The following sub-parameter is available:
D (44h) = delaytime for minimized timeout reply of the serial interface
Sub parameter: Delaytime „D“ (44h)
This parameter defines the minimum delay time (timeout) elapsed 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 4.5 ms.
Example 1: Read current delay time
SOH Adr Cmd Sub EOT CRC
Transmission
01h 20h 78h 44h 04h 7Ch
SOH Adr Cmd Sub Delaytime = 4.5 EOT CRC
Response
01h 20h 78h 44h 30h 30h 34h 35h 04h BBh
Example 2: Write new delay time
SOH Adr Cmd Sub Delaytime = 15.0 EOT CRC
Transmission
01h 20h 78h 44h 30h 31h 35h 30h 04h BDh
SOH Adr Cmd Sub Delaytime = 15.0 EOT CRC
Response
01h 20h 78h 44h 30h 31h 35h 30h 04h BDh
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.
