Forced Terminal Block Function (F-TM)
•This function forcibly enables operation via the control terminal block by turning on/off the multi-
function terminal if the frequency reference/RUN command sources are not set to the control
terminal block.
•If the Forced Terminal Block function is selected in the multi-function input selection, the Inverter
is operated with the signal from the frequency reference source and RUN command source
selected in A001 and A002, when the input signal is OFF. When the signal is ON, the Inverter is
forced to operate with the frequency reference or RUN command from the control circuit terminal
block.
•If you switch on/off this function during operation, the RUN command is reset to stop the Inverter
output. Before resuming operation, turn off the RUN command from each command source to
avoid possible danger and then input it again.
Analog Command Hold Function
•While the AHD terminal is turned on, the Inverter keeps external analog input results on hold.
•While the AHD terminal is turned on, you can use the UP/DWN function based on the reference
value of the analog signal kept on hold by this function.
•If UP/DWN selection C101 is set to "01", the Inverter can store an UP/DWN result.
•If the power is turned on with the AHD terminal turned on, or if the RS terminal is turned on and
then off, the Inverter employs the data kept on hold immediately before.
Note1: If the control function is switched via the SET/SET3 terminal with the AHD terminal turned
on, the set frequency is retained. To change the control function, turn off the AHD terminal
once, and keep the analog signal on hold again.
Note 2: If this function is frequently used, the internal storage element service life may be shortened.
