External baseblock signal
input (Minor failure)
main circuit transistor
instantance shut-off
When an external base block signal is input, the motor coasts to a stop. When the
external base block signal is removed, the inverter output is immediately turned
on at the previously set frequency.

lnvaid parameter setting
When an invalid parameter is set, it is indicated on the monitor at power up or
when the inverter is changed from the PRGM mode to the DRIVE mode.
