4. DESCRIPTION OF PARAMETERS
159
3625 Travel distance per revolution in pitch error compensation of rotation axis type
NOTE
When this parameter has been set, the power must be
turned off before operation is continued.
[Data type] 2–word axis
[Valid data range] 0 to 99999999
If the pitch error compensation of rotation axis type is performed (bit 1
(ROSx) of parameter No. 1006 is set to 0 and bit 0 (ROTx) of parameter
No. 1006 is set to 1), set the travel distance per revolution. The travel
distance per revolution does not have to be 360 degrees, and a cycle of
pitch error compensation of rotation axis type can be set.
However, the travel distance per revolution, compensation interval, and
number of compensation points must satisfy the following condition:
(Travel distance per revolution) = (Compensation interval) x
(Number of compensation points)
The compensation at each compensation point must be set so that the total
compensation per revolution equals 0.
NOTE
If 0 is set, the travel distance per revolution becomes 360
degrees.
3626
Number of pitch error compensation point at the farthest end in the negative
direction (for movement in the negative direction)
NOTE
When this parameter has been set, the power must be
turned off before operation is continued.
[Data type] Word axis
[Unit of data] Number
[Valid data range] 0 to 1023, 3000 to 4023
When using both–direction pitch error compensation, set the number of
pitch error compensation point at the farthest end in the negative direction
for a movement in the negative direction.
NOTE
1 For a movement in the positive direction, set the
compensation point number at the farthest end in the
negative direction in parameter No. 3621.
2 A set of compensation data items for a single axis should not
be set to lie astride 1023 and 3000.
