The maximum short-term starting current of the input is limited to 300 mA.
The short-circuit proof, digital output is specied in accordance with IEC
61131-2. The output current is 100 mA at 24VDC.
The output is 24VDC if modulation is possible. Inputs STO1, STO2, and ST
must be set for it.
The STO circuitry requires a control sequence specic to the F5-K card.
The X2A.16 hardware enable and all X2B STO inputs are ANDED to
activate the I7 drive enable. In addition if either the X2A.16 hardware
enable or any X2B STO inputs are deactivated the I7 drive enable will
also deactivate preventing drive modulation. Verication of the hardware
enable and STO inputs can be seen in DG.01. The X2A.16 hardware enable
will be displayed as ST-EXT (8192) and the STO input will be displayed as
STO (4096) in the DG.01 input status. Once ST-EXT and STO are activated
the I7 (1) input will be activated.
