FANUC AC SPINDLE MOTOR a series
3. EXPLANATION OF
PARAMETERS
B–65160E/02
170
SVMDRT:
Setting of the rotation direction signal (SFR/SRV) function in servo
mode (rigid tapping/spindle positioning)
0: Rotation direction function enabled
With motion command in the plus direction, the spindle rotates
counterclockwise when SFR = 1, and the spindle rotates clockwise
when SRV = 1.
1: Rotation direction function disabled
The rotation direction function of the SFR/SRV signal is disabled.
Only the function for enabling spindle motor excitation is available.
With motion command in the plus direction, the spindle rotates
counterclockwise when SFR = 1 or SRV = 1.
SYCDRT:
Setting of the rotation direction signal (SFR/SRV) function when
spindle synchronization control is used
0: Rotation direction function enabled
With spindle synchronization speed command, in the plus direction
the spindle rotates counterclockwise when SFR = 1, and the spindle
rotates clockwise when SRV = 1.
1: Rotation direction function disabled
The rotation direction function of the SFR/SRV signal is disabled.
Only the function for enabling spindle motor excitation is available.
With spindle synchronization speed command, in the plus direction
the spindle rotates counterclockwise when SFR = 1 or SRV = 1.
PCEN: Setting of the function of enabling CMR for a move command in servo
mode
0: Disables CMR.
1: Enables CMR.

PCMGSL:
Selection of position coder method/magnetic sensor method spindle
orientation
This function requires the spindle orientation function, (a CNC
software option).
In addition, setting parameter (ORIENT) to ”1” is required.
0: Position coder method spindle orientation function
1: Magnetic sensor method spindle orientation function
