Related Parameters
The parameters that are related to the sample programming are listed in the following table.
The SVC Function Module, roll No. 1 (electronic shaft) for axis X, and roll No. 2 (electronic shaft)
for axis Y are used.
Fixed Parameters
The following table gives the fixed parameter settings for both the axis X and axis Y in this
example.
Note: The default settings are used for the shaded parameters.
Setting Parameters
Axis 1 of the SVR is used as the virtual axis. The motion register addresses of the setting
parameters are OW08800 to OW0887F. Two axes of the SVC Function Module are used as
physical axes. The motion register addresses of the setting parameters for axis X are OW08000
to OW0807F. The motion register addresses of the setting parameters for axis Y are OW08080
to OW080FF.
The SVR Function Module circuit number is set to 2 and the axis number is set to 1. The SVC
Function Module circuit number is set to 1, the axis number for axis X is set to 1, and the axis
number for axis Y is set to 2.
The setting parameters for the SVR Function Module are set as follows:
• OL08803 = 0011 hex: Speed unit selection (10
n
reference units/min) and acceleration/decel-
eration rate unit selection (ms)
• OL08836 = 100: Acceleration rate (ms)
• OL08838 = 100: Deceleration rate (ms)
• OL08810 = NNNNN: Speed reference value (deg/min) --- Set from an input register.
• OW08808 = 23: Speed command code (VELO command)
No. Setting Description
0 0 Normal operation mode
1 0001 hex Finite length, software limits disabled, overtravel detection disabled, etc.
2 0000 hex Masking disabled.
4 1 Selected reference unit: degrees
5 3 Number of digits below decimal point: 3 (i.e., 1 reference unit = 0.001 degrees)
6 360000 Travel distance per machine rotation: 360,000 reference units = 360.000 degrees
81
Servomotor gear ratio term: 1 (This is because the ball screw is directly driven by the
motor.)
91
Machine gear ratio term: 1 (This is because the ball screw is directly driven by the
motor.)
29 0 Rotary motor
30 1 Incremental encoder
34 3000
Rated motor speed: 3,000 min
-1
36 1048576 Number of pulses per motor rotation: 1,048,576 P/R
OB or OL may be used in some register addresses in place of OW, depending on the data
size.
