There is an issue where an invalid error may occur when applying a correction file.
Occurs when all of the following conditions are satisfied:
JMAG-RT Viewer 21.0 is used
A map of the FEM result value is displayed or a torque-speed curve/efficiency map is created while applying a correction file to a RTT file in JMAG-RT Viewer.
There is a comma at the end of the line that specifies the number of rows and axes (or number of physical properties) in the correction table of the correction file.
E.g.) $RT_Correction_Inductance,2,6,
［Problem］
The settings for the number of rows and columns (or number of physical properties) in the correction table are not recognized properly and the application of correction file fails.
［Workaround］
Remove the unnecessary comma from the correction table format of the correction file.
For example, correct as shown below:
(Correction file format that will cause an issue）
$RT_Correction_Inductance,2,6,
↓
(Correction file format that will workaround the issue)
$RT_Correction_Inductance,2,6
