9.14.4.2 Digital Inputs 3 to 7
These inputs are programmable with the setup software. By default,all inputs are not pro-
grammed (off).
For more information refer to the setup software.
Technical characteristics
Choose the function you require in WorkBench.
Floating, reference common line is DCOM7 or DCOM8
Sink or Source type sensors possible
High: 3.5 to 30 V/2 to 15 mA , Low: -2 to +2 V/<15 mA
Update rate: firmware reads hardware input state every 250 µs
9.14.4.3 Digital Input 8 (ENABLE)
Digital Input 8 (terminal X8/4) is set to Enable function.
Floating, reference common line is DCOM8
Sink or Source type wiring is possible
High: 3.5 to 30 V/2 to 15 mA , Low: -2 to +2 V/<15 mA
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 drive is enabled by applying the ENABLE signal (Terminal X8/4, act-
ive high). Enable is possible only if input STO has a 24 V signal (
# 55). In the disabled
state (low signal) 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.
9.14.5 Digital Inputs with I/O option (X21, X22)
The drive option "IC" provides12 additional digital inputs (
# 147). These can be used to ini-
tiate pre-programmed functions that are stored in the drive. A list of these pre-programmed
functions is included in WorkBench. If an input is programmed, it must be saved to the drive.
Depending on the selected function the inputs are high or low active.
The inputs can be used with sw24 V (sink type) or switched GND (source type).
Technical characteristics
Floating, sink or source type sensors possible
High: 3.5 to 30 V/2 to 15 mA , Low: -2 to +2 V/<15 mA, Update rate: Software 250 µs
