4.2 Specification of the interface
Digital control inputs "A" (grey-pink) and "B" (violet) - digital input
signals
Via the control signals at inputs "A" and "B", the various operating states can
be selected according to the logic below.
Input level - TTL level
Low level V < 0.8
High level V > 2.0
Protection against
reverse polarity and
voltage
V ≤ 30
For cable break - Logic level "0"
Internal resistance kΩ 22
Applied logic level -
A=0/B=0 = Power stage disabled
A=1/B=0 = Direction of rotation* cw
A=0/B=1 = Direction of rotation* ccw
A=1/B=1 = Brake

Fig.3 Internal input wiring of inputs A and B
Digital control input "C" (black) - hardware enable
The control input "C" is used for targeted switching on/off of the power stage
of the drive, independent of the supply voltage. In addition, this input is used
for switching on again (acknowledgement) after a fault shut-off (fault status
at digital output "D"). Switch-on/acknowledgement takes place with a change
of the signal level from 0 to 1.
Input level - TTL level
Low level V < 0.8
High level V > 2.0
Protection against
reverse polarity and
voltage
V ≤ 22
For cable break - Power stage "OFF"
Internal resistance kΩ 8
Applied logic level -
0 = Power stage switched off
1 = Power stage switched on
