IPM motor control <IPM>
4
PARAMETERS
(2) Valid/invalid statuses of I/O terminal functions during the test operation
1)Input terminal function selection (Pr.178 to Pr.189)
All assignable functions are valid.
2)Output terminal function selection (Pr. 190 to Pr. 196)
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

Function
*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 152.
*2 When the operation is switched to the test operation, "0" is
displayed. When IPM motor control is selected again after a test
operation, the output current peak value and the electronic thermal
relay load factor from the last operation are displayed.
