 Purpose
If final output voltage and current deviates due to characteristics of output devices and methods of
connection, correct the "deviation" and adjust outputs.
 Details of functions
This function corrects conversion values of output voltages and currents at 2 points, 0% and 100%,
as shown in the figure below.
The correctable range is from − 5% to +5% each of the minimum and maximum values of outputs.
The correctable range for each output range is as follows.
Set by SDO communications.
The target indexes are as follows.
•
Upper limit correction: 3212 hex Analogue Output Adjustment High Execute (user adjustment
execution (upper limit))
•
Lower limit correction: 3215 hex Analogue Output Adjustment Low Execute (user adjustment
execution (lower limit))
For the correction procedure, refer to the information in the corresponding index of "Appendix A-1
Object Dictionary" in page A-47.
