MACHINE PARAMETERS
SOFT: V02.2X
Spindle parameters
SMOTIME (P46)
Sometimes the axis does not respond as desired on particular movements. Movements with
handwheel or when the CNC internally transforms the programmed coordinates (C axis, etc.).
In these cases, the response of the spindle may be smoothed by applying a filter to the speed
changes.
This filter is set by parameter SMOTIME that indicates the duration of the filter in milliseconds, value
given by general parameter LOOPTIME (P72).
To obtain a better response, parameter SMOTIME of the axes interpolating with each other should
be set with the same value.
The spindle's response can also be smoothened when working in open loop (M3, M4). In this case,
spindle parameters OPLACETI (P45) and SOMTIME (P46) must be used.
ACCTIME2 (P47) PROGAIN2 (P48) DERGAIN2 (P49)
FFGAIN2 (P50)
These parameters define the second set of gains and accelerations. They must be set like the
parameters that define the first set.
To select the second set of gains and accelerations, set general parameter ACTGAIN2 (P108)
correctly or activate the CNC’s general logic input ACTGAIN2 (M5013).
Possible values
Integers between 0 and 64 times the value assigned to general parameter LOOPTIME (P72).
If LOOPTIME = 0 (4 ms), the maximum value that could be assigned to SMOTIME will be 64 x 4 = 256 ms.
Default value: 0 (not applied)
