4.3.8. Read / write parameter timeout at bus error RS485, command „j“ (6Ah)
This command is for read or write the system time: timeout at bus error. Parameter range is within 00,1 s to
99,9 s. Tolerance: ±7% at minimum time; < 1‰ at maximum time, approx. 1% at 1 s.
Function: RS485 monitoring during motive shaft positioning operations. If there is no interface activity within the
programmed timeout the motor will stop (EMERGENCY OFF) upon occurrence of a bus error or inactive
control. A motor restart requires transmission of profile (command „S“ or „V“) together with the start signal
(command „D“). Parameter 0.00 s means function disabled.

4.3.9. Read / write parameter motor system time, command „k“ (6Bh)
This command is for read or write the individual motor system times. Parameter range is within 00,1 s to 99,9
s. Tolerance: ±7% at minimum time; < 1‰ at maximum time, approx. 1% at 1 s.
The following 2 parameters are available:
Loop: Delay time at turning point during loop operation.
Trailing error: Timeout of motor signals, if shaft does not rotate after motor start.
Example 1: Read parameter (loop = 1,0 s; trailing error = 3,5 s)
