PRLOAD
PRLOAD Automatic parameter setting function
0 : Does not perform automatic parameter setting. (standard setting
value)
1 : Performs automatic parameter setting.
After setting a desired motor model code in parameter No. 4133 and
setting this bit to 1, turn off the power to the CNC, then turn on the
power to the CNC again. The parameters (No. 4000 to No. 4175) for
the αCi series spindle corresponding to the model code are
automatically initialized. Upon completion of automatic setting, this
bit is automatically set to “0”.
NOTE
With FS15i, the parameter address of this function is
different, namely, bit 0 of No. 5607 is used. Moreover,
note that the meanings of settings are reversed as
follows.
0 : Performs automatic parameter setting.
1 : Does not perform automatic parameter setting.
In this case, set a model code in parameter No. 3133.

Maximum motor speed
Unit of data : 1min
-1
Valid data range : 0 to 32767
Standard setting value : Depends on the motor model.
This parameter sets a maximum spindle motor speed.
WARNING
The spindle motor may rotate at the maximum
spindle motor speed specified by this parameter.
Therefore, this parameter must not be set to a
value greater than the maximum rotation speed
indicated by the specification of the spindle motor.

Velocity loop proportional gain on velocity control mode (LOW) CTH1A=1
Unit of data :
Valid data range : 0 to 32767
Standard setting : Depends on the motor model.
This data is used to set the velocity loop proportional gain on velocity
control mode.
When the input signal CTH1A = 0, (HIGH) is selected. When the
input signal CTH1A = 1, (LOW) is selected.
