FANUC AC SPINDLE MOTOR a series
3. EXPLANATION OF
PARAMETERS
B–65160E/02
176
RVSVCM:
Specifies whether the speed command and speed feedback signal are
reversed in slave operation:
0: Not reversed.
1: Reversed.
ALSP: Specifies how to turn off the power to the motor when AL–24 (serial
transfer data error) is issued.
0: The power to the motor is turned off once the motor has been
decelerated and stopped.
1: The power to the motor is turned off immediately.
Set this bit to 1 to turn off the power to the motor immediately upon the
issue of a spindle alarm.
PCGEAR:
Specifies whether the arbitrary gear ratio (between the spindle and
position coder) function (proximity switch) is used.
0: Not used.
1: Used.
Set this bit to 1 to use the function for spindle orientation with a reference
switch.
Set an arbitrary gear ratio in parameter Nos. 4171 to 4174.
LDTOUT:
Specifies whether the load detection signals (LDT1, LDT2) are output
during acceleration/deceleration.
0: Not output during acceleration/deceleration.
1: Output (at all times) during acceleration/deceleration if the level set
in the parameter is exceeded.
TRSPCM:
Specifies the method of output compensation (9D00.D).
The method varies with the motor model.
OVRTYP:
Specifies an analog override type (9D00.D).
0: Override of linear function type
1: Override of quadratic function type
