Spindle parameters
SYNPOSOF (P53)
When both spindles are synchronized in position, the second spindle must follow the main spindle
maintaining the offset set by function G30.
The parameter of the main spindle sets the maximum error allowed. If this value is exceeded, no
error message is displayed and the movement is not stopped. It only sets general output SYNCPOSI
(M5559) low.
SYNSPEOF (P54)
When both spindles are synchronized in speed, the second spindle must turn at the same speed
as the main spindle.
The parameter of the main spindle sets the maximum error allowed. If this value is exceeded, no
error message is displayed and the movement is not stopped. It only sets general output SYNSPEED
(M5560) low.
ACCTIME3 (P55) PROGAIN3 (P56) DERGAIN3 (P57)
FFGAIN3 (P58)
These parameters define the third set of gains and accelerations. The CNC uses the third set when
working with synchronized spindles (G77).
They must be set like the parameters that define the first set.
The spindles (main and second) must have their own feedback devices and their parameters must
be set in such a way that their behaviors are similar.
When working with FFGAIN3 (P58) = 100, set the MAXGEAR and MAXVOLT parameters properly.
ACCTIME4 (P59) SECACESP (P60)
In order to compensate for the lack of a linear response on some spindles, it is possible to use two
accelerations: ACCTIME3 for low speeds [up to the one set by SECACESP (P60)] and ACCTIME4
for the rest of higher speeds.
Once the spindles are in synchronism, the CNC applies to both spindles the accelerations defined
for the main spindle.
Possible values
Between 0 and 99999.9999 degrees.
Default value: 2 degrees.
Possible values
Integers between 0 and 65535 rpm.
Default value: 1 rpm.

For DERGAIN3 (P57) = 0.
For FFGAIN3 (P58) = 100.
