9.7. Inputs and Outputs
The Everest XCR Servo Drive provides several inputs
and output terminals for parameter observation and drive
control options.
4x
5 V non-isolated single ended digital inputs
(IN1, IN2, IN3, IN4).
1x
±10V differential 16 bit analog input
4x
5 V non-isolated digital outputs
(OUT1, OUT2, OUT3, OUT4).
9.7.1. Digital Inputs Interface
The non-isolated digital inputs are ready for 5 V or 3.3 V digital levels. The following table shows their electrical
specifications.

Next figure shows an example of how to wire digital inputs with various input options. For higher voltage systems
like 12 V or 24 V a series resistance should be connected to the input.
Non-isolated I/O
Everest XCR inputs and outputs are not isolated.
The reference voltage of the drive (GND_D) and the
ground of the devices connected to I/Os must be the same. Otherwise, inputs or outputs may be damaged.
For electromagnetically noisy environments and for signals that could be user-accessible and cause
electric shock, reinforced isolation is necessary. It is recommended to use isolators like Silicon Labs Si87xx
series, Texas Instruments ISO121x isolators.
