Mitsubishi Electric FR-F820-00046 Instruction Manual page 171

• Start-time tuning start external input (X28) signal
 Output terminal function selection (Pr.190 to Pr.196)
• Electronic thermal O/L relay pre-alarm (THP) signal
• Start time tuning completion (Y39) signal
Parameters referred to
Pr.178 to Pr.189 (Input terminal function
Pr.190 to Pr.196 (Output terminal function
 Status of the monitoring during the test operation
○: Enabled
×: Disabled (0 is displayed at any time.)
∆: A cumulative total before the test operation is displayed.

*1 The monitoring-enabled items differ depending on the output interface (operation panel, parameter unit, terminal FM/CA, or terminal AM). For the
details, refer to
*2 When the inverter operation is switched to the test operation, the indication is changed to 0. When PM motor control is selected again after the
test operation, the output current peak value and the electronic thermal relay load factor from the last operation are displayed.
*3 The output is enabled via terminal AM only.
*4 When the inverter operation is switched to the test operation, the accumulated thermal value is reduced because the output current is considered
as 0.

 Changing the control method with external terminals (RT signal, X18
signal)
• Control method (V/F control or Advanced magnetic flux vector control) can be switched using external terminals.
The control method can be switched using either the Second function selection (RT) signal or the V/F switchover (X18)
signal.
• When using the RT signal, set the second motor in Pr.450 Second applied motor. Turning ON the RT signal enables the
second function, enabling the switchover of the control method.
