9. SPINDLE SPEED FUNCTION
899
[Operation] When this signal is set to 1, the control unit operates as follows:
-- Activates the parking function for the second spindle placed under
simple spindle synchronous control.
When the SPK bit (bit 7 of parameter No. 4800) is set to 1, #7 of G031
functions as this signal.
[Classification] Input signal
[Function] This signal monitors the synchronization error between the two spindles
when simple spindle synchronous control is applied.
[Operation] This signal is set to 1 in the following case:
-- When the synchronization error between the two spindles is equal to
or greater than the value set in parameter No. 4811
This signal is set to 0 in the following case:
-- When the synchronization error between the two spindles is less than
the value set in parameter No. 4811
Phase error monitor signal SYCAL is not a latch signal, instead being
switched between 0 and 1 by constantly monitoring whether the position
error between the two spindles is within the value set in parameter No.
4811.
In addition to the above signals, the following spindle control unit signals
for the serial spindles must be controlled so that the second spindle
functions in the same way as the first:
<G0070 to G0073> (input), <F0045 to F0048> → For the first serial
spindle
<G0074 to G0077> (input), <F0049 to F0052> → For the second serial
spindle
