B-63943EN-1/02 11.SPINDLE SPEED FUNCTION
- 1481 -
This signal is valid only when bit 4 (SSS) of parameter No. 3704 is set
to 0.
When bit 5 (SCB) of parameter No. 4800 is set to 1, an address of n =
0 is valid.
NOTE
Even if this signal is once set to 1, this signal is set
to 0 when the speed difference exceeds the value
set in parameter No. 4810 for a cause such as
cutting load variation.
Spindle phase synchronization control completion signal of each spindle
FSPPH1~FSPPH4<Fn289#0~Fn289#3>
[Classification] Output signal
[Function] These signals post that spindle phase synchronization control (phase
matching) with each spindle set as a slave spindle is completed.
[Output condition] This signal is set to 1 in the following case:
- This signal is output when phase matching is completed with the
spindle phase synchronization control signal (when the error
pulse difference between the two spindles is equal to or less than
the value set in parameter No. 4810) after the two spindles have
reached the speed equivalent to a specified spindle synchronous
speed in the spindle synchronous control mode.
This signal is set to 0 in the following cases:
- In the spindle synchronous control mode, the phase matching of
two spindles is not completed.
- In the spindle synchronous control mode, the error pulse
difference between two spindles is greater than the value set in
parameter No. 4810.
- The spindle synchronous control mode is not set.
- The spindle phase synchronization control mode is not set.
These signals are valid only when bit 4 (SSS) of parameter No. 3704
is set to 1 and bit 5 (SCB) of parameter No. 4800 is set to 0.
NOTE
1 Even if this signal is once set to 1, this signal is set
to 0 when the speed difference exceeds the value
set in parameter No. 4810 for a cause such as
cutting load variation.

spindle and actual signal address, see the
