Fuji Electric RYS...S3-VVS Series - Frequency Dividing Output

MHT258a (Engl.)6-14
6.2.3 Frequency dividing output
The pulse count in proportion to motor rotational quantity will be output.
The output pulse count can be set for the freq. dividing output terminals [FA], [*FA], [FB], [*FB], [FZ], and [*FZ]. The output pulse count is
common to position control, speed control and torque control.
Pulse width : t11 ≧ 1μs (equivalent to 500kHz)
A-phase and B-phase signals are 50% duty.
The output pulse counts of A-phase and B-phase signal are determined by system para. 79 setting.
Z-phase signal is output one pulse per revolution. The pulse width depends on the A-phase output pulse count.
A-phase signal and Z-phase signal are synchronized. Recommended output frequency is approx. 500kHz. The output frequency is not
restricted by the amplifier.
The position of the motor output shaft has no relation with Z-phase.

The freq. dividing output pulse count per one rotation of motor is set. The output form is two 90° phase-different signal.
When the motor rotates forward, a B-phase advanced pulse is output. This does not depend on the rotational direction changeover setting
(system para. 80)
Two 90° phase-different signal is output based on the level at the time of power on.
Max. output frequency depends on the performance of IC (differential driver: AM26LS31 or equivalent) for output terminal. The output
frequency is not restricted by the amplifier.
