MC_2903:
Spindle Motor Type
The spindle-axis motor type is identified
by the motor name. Inputting the wrong
motor number can result in undesired
axis behavior or motor damage.
None [Default]

MC_2904:
Spindle Position
Encoder Connection
Selects the measuring system input for
the spindle-axis position encoder
connection.
NONE
[Default]
X1
X2
X3
X4
X6
MC_2905:
Spindle Position
Encoder Sinewave
Period
Provides the number of encoder periods
corresponding to the spindle-axis
position displacement as entered in
MC_2906. The sine signal of the
encoder is interpolated to obtain 1024*
the nominal resolution.
The input frequency of the encoder to
the CNC may not exceed:
350 kHz for an encoder with 1Vpp
signal
NOTE:
Both MC_2905 and MC_2906
may be multiplied by the same factor to
obtain integer values. Also, division by
the same factor is possible as long as
the result is an integer.

sample calculations.
Range (0–20160)
1 [Default]
MC_2906:
Spindle Position
Encoder Line Count
Spindle-axis grating pitch.
Range (1–100)
20 [Default]
MC_2908:
Spindle Position
Encoder Signal Type
Defines the signal type for the spindle-
axis encoder.
1Vpp [Default]
