5. If the analog equipment on the application side only accepts a single-
ended signal (not recommended), the accuracy of the analog signal may
be influenced by the resistor R* mentioned in Note 4. For this reason a
low value is chosen.
6. Connect the NYCe 4000, a power supply or other equipment on a metal
frame or mounting base and make sure there is a galvanic contact.
7. For proper use, this ground may not be connected to motor or digital I/O
ground

Digital Inputs
Characteristic
Description
Number of digital inputs
8, divided in 2 groups:
●
DigIn0 ... DigIn3 with DigComm0
●
DigIn4 ... DigIn7 with DigComm1
Functions
General Purpose Digital input
●
24V Hall sensors can be connected to the digital
inputs
–
DigIn0, DigIn1, Digin2 for axis0
●
Position latching
●
Change of state events (1 per MCU time
sample)
●
Count transitions interval (1 per MCU time
sample)
●
DigIn6 can be defined as disable drive input for
axis0
Disable drive functionality is defined through the
function SacWriteParameter, see NYCe 4000
Software User Manual.
The power amplifier is disabled after the disable drive
input is detected active for approximately 500 µs.
