Function PolarityDescription
Position trigger
Position trigger 1 … 4 Thepositiontriggerscanbeusedtopassoninformation
about the logical status of position triggers, rotor
position triggers and cam c ontroller units to the digital
outputs.
High active
Teach
Acknowledge teac h The signal goes to Low with the rising edge at the Teach
input and back to High with the falling edge at the Teach
input.
Low active
Saving proc ess in operation The signal goes to High as soon as a saving procedure is
started and is extinguished automatically after the saving
process has been completed.
High active
Functional safety
STO active Signals that safe status S TO (Safe torque off ) is ac tive. High active
STO requested Signals that safe status S TO (Safe torque off ) has been
requested.
High active
Tab. 6.28 Function overview of the digital outputs
The digital outputs “STO active” and “STO requested” must not be used in a
safety-directed manner.
Analogue inputs
Through the analogue inputs, setpoint values can be specified as controller input data via a corre s-
pondingly scaled input signal.
In the factory settings, AIN1 and AIN2 are not available, since they are pre-assigned with other func-
tions as DIN12 or DIN13.

Tab. 6.29 Analogue inputs
The specified value defines how the relevant input signal is converted into a torque, a speed or a
positioning setpoint value. Input voltages in the value ra nge from –10 V … +10 V are processed.
• Specify in the respective registers in the FCT which value of th e respect ive input variables corres-
ponds to an input voltage of 10 V. The scaled range corresponds to a linear characteristic curve
symmetric to the zero point (e.g. –1000 R/min … +1000 R/min).
