Test operation and gain adjustment of the PM sensorless vector control
(2) Valid/invalid statuses of I/O terminal functions during the test operation
1)Input terminal function selection (Pr. 178 to Pr. 182)
All assignable functions are valid.
2)Output terminal function selection (Pr. 190, Pr. 192)
Some functions have restrictions. For details, refer to the table below.
{: Valid, ×: Not output as there is no output current
(3) Valid/invalid statuses of monitor outputs during the test operation
{: Valid, ×: Invalid (always displays 0)
U: Displays accumulated value before the test, ⎯: Not monitored

*1 Monitor output is valid or invalid depending on the monitor type
(operation panel display, parameter unit display, or terminal FM/
AM). For details, refer to page 117.
*2 When the operation is switched to the test operation, "0" is
displayed. When the PM sensorless vector 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, drive unit thermal load factor, and the electronic
thermal relay load factor.
