I/O circuit diagrams
Fig. 12: Analogue input circuit diagram (internal)
The analogue inputs are executed as differential inputs. Both inputs use the same reference
input.
The analogue inputs can be used flexibly:
Specification of set-points for current, speed or position
Connection of actual value encoders for speed or position
Use as a free measurement input (queried via the interface)
Fig. 13: Digital input circuit diagram (internal)
The digital inputs are switchable from the input level (PLC/TTL). The digital inputs can be
configured for the following purposes (see the Drive Functions):
Digital input for reference and limit switches
Connection of an external encoder
PWM (Pulse Width Modulation) set-point specification for current, speed and position
So that the voltage drop on the supply side does not affect the speed specification
value, connect the analogue input ground (AGND) to the power supply ground (GND).
