4. DESCRIPTION OF PARAMETERS
B–63980EN/01
102
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.
3627
Pitch error compensation (absolute value) at reference position when a move-
ment to the reference position is made from the direction opposite to the direc-
tion of reference position return
NOTE
When this parameter has been set, the power must be
turned off before operation is continued.
[Data type] Word axis
[Unit of data] Detection unit
[Valid data range] –32768 to 32767
Set the absolute value of pitch error compensation at reference position
when a movement to the reference position is made from the negative
direction if the direction of reference position return (bit 5 (ZMI) of
parameter No. 1006) is positive or from the positive direction if the
direction of reference position return is negative.
