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.
OB or OL may be used in some register addresses in place of OW, depending on the data
Information
size.
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
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)
0 Normal operation mode
Finite length, software limits disabled, overtravel detection disabled, etc.
Masking disabled.
1 Selected reference unit: degrees
3 Number of digits below decimal point: 3 (i.e., 1 reference unit = 0.001 degrees)
Travel distance per machine rotation: 360,000 reference units = 360.000 degrees
Servomotor gear ratio term: 1 (This is because the ball screw is directly driven by the
1
motor.)
Machine gear ratio term: 1 (This is because the ball screw is directly driven by the
