Servo Motor Hollow Encoder——GSM48 Series

Applications

Widely used in the field of automatic control AC servo unit, particularly suitable for use in servo motor supporting

Features

* Internal ASIC devices, high reliability, long life, strong anti-interference.

* Wide range of resolutions, and does not require signal conditioning.

* With A, B, Z and U, V, W six-channel signal output can be connected with standard line driver (26LS31) RS422, can provide 12 output signal, and is compatible with TTL

Output phases

Waveform ratio= X1+X2=0.5T±0.1T

X3+X4=0.5T±0.1T

Phase difference= Xn≥0.15T(n=1、2、3、4)

Z signal width: Tz=0.5T

Signal location accuracy:

A, B phase absolute angular error ≤ 0.2T

Periodic error ≤ 0.05T

T = 360 ° / N (N is the number of pulses per revolution output)

Cycle P = 360 ° / N1 ± 1.5 ° (N1 = 2,3,4)

Phase difference Yn = P / 6 ± 1.5 ° (n = 1,2,3,4,5,6)

A, B phase U, V-phase position makes no provisions

Z phase and U phase relationship: C ≤ ± 1 ° (mechanical angle)

A phase difference of 90 ° signal with a zero signal.
