3.Typical applications
Corrugator cross-cutter: 10,000-line encoder stable at 12,000 rpm
Stacker crane: SSI absolute, position retained after power-loss, no homing on restart
Robot joints: 20-bit feedback, arc-interpolation error ≤ 0.01°
4.Installation notes
35 mm DIN-rail or M4 panel mount; terminal torque 0.2 N·m; green LED steady = OK

6.Quick-selection hint
For cable >10 m use 0.34 mm² shielded twisted pair, shield earthed at NTAC-02 end only.
If encoder current >200 mA add a separate 24 VDC supply to avoid voltage drop and count jumps.
7.FAQ
Q: Can A/B/Z all run at 1 MHz simultaneously?
A: Yes—A, B, Z opto-isolated; total ≤ 2 MHz.
Q: Compatible with ACS580?
A: Requires firmware v2.7 or later; enable “NTAC-02” hardware ID in DriveStudio.
