9.7.1 Digital Inputs
The drive provides 3 digital inputs. These can be used to initiate pre-programmed functions
that are stored in the drive. A list of these pre-programmed functions is included in the
WorkBench. If an input is programmed, it must be saved to the drive. By default,all inputs are
not programmed (off). For more information refer to the setup software.
Depending on the selected function, the inputs are high or low active. The inputs can be
used with sw24 V (source type) or switched GND (sink type). Digital input filter can
be set in WorkBench to change sensitivity of the inputs (see Online Help).
Wiring diagram:
Digital Inputs 1 and 2
These inputs are particularly fast and are therefore suitable for latch functions, for example.
Technical characteristics:
Floating, reference common line is DCOM3
Sink or Source type sensors possible
High: 15 to 30 V / 2 to 15 mA , Low: -3 to +5 V / <1 mA
Update rate: firmware reads hardware input state every 250 µs
High accuracy latch: motor feedback position or interpolated time is latched or captured
within 2 µs of input signal transition (with digital input filter set to 40 ns)
The AKD-N capture engine is polled every 62.5 µs (16 kHz) by the firmware
Digital Input 3
