• bii_1_frg = Enable
In the case of a 0/False signal, an emergency stop is performed,
which results in a malfunction and must be acknowledged.
• bii_1_reset = Reset
When changing from 0/False to 1/True, the malfunction is ac-
knowledged/reset, which stops the drive.
Malfunctions can only be acknowledged if they have previously
been resolved.
• bii_1_bwg_pf = Movement via P flank
In the case of a 1/True signal, only one movement is executed
in the case of a positive edge (signal change from 0 to 1), at the
corresponding movement functions (e.g. tapping). This is to en-
sure that after the drive has been stopped, it can only be acti-
vated as soon as a positive edge (change from 0 to 1 signal) is
detected. Thus, an independent start-up can be prevented (e.g.
when tapping.
• bii_mot_strom_nenn = Nominal motor current
The engine current can be limited via the rei_sw_i value. In the
case of a 1/True signal at the input, the engine is set to its no-
minal power value, irrespective of the set target value.
