Pulse Output (Ffa, *Ffa, Ffb, *Ffb, Ffz, *Ffz); Z-Phase Output (Fz, M5); Analog Monitor Output (Mon1, Mon2, M5) - Fuji Electric ALPHA7 User Manual

2.1.3.2

Pulse Output (FFA, *FFA, FFB, *FFB, FFZ, *FFZ)

The pulses proportional to the motor revolutions are output as A/B phase pulse.

The number of output pulses per motor revolution can be specified in the parameter (PA1_08).

The output pulse frequency is proportionate to axis revolution speed.

Max. output frequency: 1 [MHz]

The output pulse phase (A or B phase advance) to the motor revolution direction can be specified
in the parameter (PA1_11).

The FFZ and *FFZ signals output one pulse per motor revolution. The output position can be
adjusted in the parameter (PA1_12).
2.1.3.3

Z-Phase Output (FZ, M5)

The Z-phase output is an open collector output of the FFZ or *FFZ signal.
The current can flow up to 30 [V] DC/50 [mA].
2.1.3.4

Analog Monitor Output (MON1, MON2, M5)

The analog monitor output is the analog voltage output terminal of the servo amplifier. The output is
specified with a parameter.
Observe after 2 seconds or longer have elapsed since turning ON the power.
The output voltage will be unstable immediately after turning ON the power, and after turning OFF the
power.
