9.10.2 Digital Input (ENABLE, X15)
Digital Input (terminal X15/3) is set to the Hardware Enable function.
Technical characteristics:
Floating, reference common line is DCOM
Sink or Source type wiring is possible
As per IEC61131-2 type 1
ON: 15 VDC to 30 VDC, 2 mA to 15 mA, OFF: -3 VDC to 5 VDC, < 1 mA
Galvanic isolation for 250 VDC
Update rate: direct connection to hardware (FPGA)
The Hardware Enable input and the Software Enable signal (via fieldbus or WorkBench) are
serial, that means wiring of Hardware Enable is mandatory.
The output stage of the AKD-N drives, which are connected to the AKD-C are enabled by
applying the ENABLE signal (Terminal X15/3). Enable is possible only if the input STO-
Enable 1 or 2 (valid for DC power strings 1 or 2) has a 24 V signal (
# 38). In the disabled
state the connected motor has no torque.
A software enable by means of the setup software is also required (AND link), although this
can also be permanently enabled with WorkBench.
The input can be used with sw24 V (source type) or switched GND (sink type). See
diagrams below for typical examples of digital input wiring.
