Z-Phase Detection Command: Sequence Input Signal (Reference Value -) - Fuji Electric ALPHA7 User Manual

Z-phase detection command: Sequence input signal (Reference value -)

The Z-phase detection is enabled while the signal is turned on.
This signal is enabled only for VS type.
 Function
If Z-phase of the servomotor is detected while the this function is activated, bit 6 in word 9 in IQ
area (Z-phase signal detection) is turned on.
Then the motor feedback position at this time is output to 2nd and 3rd word in IQ area.
Furthermore, the timing of holding (holding initial detection, each Z phase detection) with the
PA2-92: SX extension function can be changed.
