4.3.7. Read / write measuring unit „i“ (69h)
The command is utilized to read or write the measuring unit in mm or inches.
Data = 0 (30h) = mm
Data = 1 (31h) = inch

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