4. DESCRIPTION OF PARAMETERS
21
This parameter specifies the width of allowable variation in power control
speed.
This parameter is effective when parameter No. 15450 is 0. To set a value
equal to or greater than 256, use parameter No. 15450. Depending on the
setting of the bit 6 (SDB) of parameter No. 15096, specify this parameter
as described below:
If SDB = 0, set a speed.
Thus, the permissible speed fluctuation width is always the same.
If SDB = 1, set the ratio to the velocity specified with the velocity
command after a switch to power control mode (0 to 100%).
(Example) When G63P1 is issued and the system switches to power
control mode:
If SUB = 0:
If this setting is 10, the permissible velocity fluctuation
width is 10 mm/min.
If SUB = 1:
If the velocity specified with the velocity command is 200
mm/min and this setting 10, the permissible velocity
fluctuation width is 200 mm/min.

[Data type] Bit
PCP During power control, the output is:
0 : Not controlled according to the feedrate.
1 : Controlled according to the feedrate.
PCF During power control, the frequency is:
0 : Not controlled according to the feedrate.
1 : Controlled according to the feedrate.
PCD During power control, the duty ratio is:
0 : Not controlled according to the feedrate.
1 : Controlled according to the feedrate.
SDB The method of setting a permissible velocity fluctuation width in power
control mode (parameter No. 15095) is to:
0 : Directly specify the velocity (mm/min)
1 : Set the ratio to the velocity specified with the velocity command after
a switch to power control mode (0 to 100%).
EGM In edge machining mode and start–up machining mode:
0 : Power control mode is canceled.
1 : Power control is stopped only during the return distance movement in
edge machining and start–up machining.
Edge machining mode and start–up machining mode refer to the states in
which E numbers specifying the respective cutting conditions for edge
machining and start–up machining have been selected.
