Wiring for a simplified version with panic button / emergency stop. When using this circuit ensure the difference
between STO_1 and STO_2 signals changing the state is less than 1.4 s to prevent an abnormal situation. When
using various protective switches connect them in series.
Wiring for a simplified version using the Everest-XCR +5V_out supply is shown next (no need for 24 V supply). Note
that as the 5V_OUT is connected to other circuits like feedbacks and isolation on STO inputs is lost.
9.4.1. STO bypass (needed when no STO functionality is implemented)
If STO is not be used, it must be override with 3 wire jumpers on the I/O connector, otherwise it will not be possible
to enable the drive. See following figure:
STO1 and STO2 signals should always change at same time with a maximum of 1.4 s mismatch. This is
necessary to have 2 channel redundancy and allow diagnostics, as a mismatch will cause a abnormal
fault.
In order to ensure this, do
not
add big capacitors (> 100 µF) in parallel to the STO inputs as this may cause
faults during activation or deactivation of the STO.
