Technical Frequently Asked Questions
What rotation speed does the M345NC support?
30,000 rpm continuous; maximum intermittent RPM is 30 % higher than continuous RPM. Bearing life is 1.5 × 109 revolutions (at 1000 rpm and with a load of 1/4 of the maximum allowed).
What hollow shaft diameters does the magnetic actuator support?
Hollow shaft of Ø4, Ø5, Ø6, Ø8 or Ø10 mm.
What communication interface and data format does the M345NC encoder use?
It uses SSI synchronous serial interface under the RS422 physical standard, delivering position data in natural binary code with an external clock of up to 500 kHz.
