SinCos encoder input circuit for axis1
Notes
1. The pins on the I/O connector at the back of the drive module have
already a meaning, as shown in
tab. 13-34 "Encoder inputs assignment"
. These names are respected, also for the signals that are
connected with the NY4199 SinCos Option module.
2. The drive module NY4140 supports only one encoder. This still holds
while applying an NY4199 SinCos Option module. The remaining I/O
are available for other functionality.
3. 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.
4. When switching off the power of the encoder the software behavior is as
follows.
●
A power loss error is generated on the axis.
●
The axis will go to the error state and be set 'not homed'.
To recover from this situation, you must switch on the encoder power,
reset and home the axis.
