Monitor output is valid or invalid depending on the monitor type
(operation panel display, parameter unit display, or terminal FM). For
details, Refer to page 152.
When the operation is switched to the test operation, "0" is displayed.
When IPM motor control is selected again after a test operation, the
following monitored items from the last operation are displayed: output
current peak value, motor thermal load factor, inverter thermal load
factor, and the electronic thermal relay load factor.
