MACHINE PARAMETERS
SOFT: V02.2X
Spindle parameters
CONCLOOP (P62)
It indicates whether the spindle operates in closed positioning loop (as if it were an axis) or not.
In order to operate in closed positioning loop, the spindle must have an encoder and a good servo
system for the full speed range.
When working with M19, the first two sets of gains and accelerations are used regardless of the
value given to this parameter.
When working in closed positioning loop (M3, M4, M5) the third set of gains and accelerations is
used: ACCTIME3, PROGAIN3, DERGAIN3 and FFGAIN3.
When working with synchronized spindles (G77), third set of gains and accelerations is used.
Therefore, the CONCLOOP parameter of the spindle to be synchronized should be set to "YES"
SYNMAXSP (P63)
It is set for the main spindle. It indicates the maximum turning speed when the spindle are
synchronized (G77).
M3M4SIM (P64)
In TC mode, it indicates the turning direction of the corresponding spindle with each key for turning
direction.
For example in a live tool cycle, it will take into account the value assigned to the spindle that has
been defined as live tool whereas in a deep hole drilling cycle, it will consider the one assigned to
the main spindle.
SINMAGNI (P65)
It indicates the multiplying factor (x1, x4, x20, etc.) that the CNC must apply only to sinusoidal
feedback signals of the spindle.
For square feedback signals, this parameter must be set to 0 and the CNC will always apply a
multiplying factor of x4.
Spindle feedback resolution is set by spindle parameters NPULSES (P13) and SINMAGNI (P65).
Value Meaning
EZ It operates in open loop.
YES It operates in closed position loop (as if it were an axis).
Default value: EZ
Possible values
Integers between 0 and 65535 rpm.
When set to 0, there is no limit.
Default value: 1000 rpm.
M3M4SIM (P64) = 0
Possible values
Default value: 0
= M3 = M4
M3M4SIM (P64) = 1 = M3
= M4
Possible values
Integer numbers between 0 and 255.
Default value: 0
