8-5 Function of the Analog Output Slave Unit
8
8-5-3 User Adjustment
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.
