General machine parameters
ACTGAINT (P185)
The axes and the spindle can have 3 sets of gains and accelerations. By default, the CNC always
assumes the first set indicated by the parameters of the axis or of the spindle ACCTIME, PROGAIN,
DERGAIN and FFGAIN.
Parameter ACTGAINT indicates when the CNC assumes the third set of gains and accelerations,
indicated by the parameters of the axis or of the spindle ACCTIME2, PROGAIN2, DERGAIN2 and
FFGAIN2.
This parameter has 16 bits counted from right to left.
Each bit has a function or work mode associated with it. By default, all the bits will be assigned the
value of ·0·. Assigning the value of ·1· activates the corresponding function.
Every time each of the functions or work modes assigned to the bits of general parameters
ACTGAIN2 (P108) or ACTGAINT (P185) is activated, the CNC checks the value assigned to the
bit corresponding to that function in these parameters and acts as follows:
• If the bit of ACTGAINT2 is set to ·0· and the bit of ACTGAINT is set to ·0·, it applies the first set
"ACCTIME, PROGAIN, etc".
• If the bit of ACTGAINT2 is set to ·1· and the bit of ACTGAINT is set to ·0·, it applies the third
set "ACCTIME2, PROGAIN2, etc".
• If the bits of ACTGAINT is set to ·1· and the bit of ACTGAIN2 is set to ·0·, it applies the third set
"ACCTIMET, PROGAINT, etc".
When that function or work mode is deactivated, the CNC applies the first of the sets "ACCTIME,
PROGAIN".
Considerations to bear in mind.
The change of gains and accelerations is always made at the beginning of the block. When working
in round corner (G5), the change does not take place until G07 is programmed.
The gains and accelerations may also be changed from the PLC. To do that, there is a general logic
CNC input ACTGAINT (M5063). Every time this input is activated, the CNC selects the third set of
gains and accelerations regardless of the active operating mode or function.

Sample
When setting ACTGAINT = 1000 0000 0001 0000 and ACTGAIN2 = 0000 0000 0000 0000, the CNC applies
the third set to all the axes and the spindle whenever function G1 or the JOG mode is selected.
