D External Baseblock Command (Set Value = 13 or 14)
The baseblock command can be input remotely to the Inverter by setting n035 to 13 (i.e., the NO contact
is ON) or to 14 (i.e., the NC contact is OFF).
The baseblock is the status of the Inverter with output turned OFF. The motor will coast to a stop if the
baseblock command is input to the Inverter. The Inverter, however, will hold the output frequency and if
the baseblock command is released, a speed search will be carried out from the frequency held by the
Inverter, and the motor will be restarted. To clear the held frequency, turn OFF the run command. When
the run command is turned OFF, the held frequency will change to zero.
D Speed Search Command (Set Value = 15 or 16)
The Inverter in speed search operation restarts the motor without stopping the motor while the motor is
coasting.
The Inverter in speed search operation makes it possible to smoothly switch over power supply to the
motor from commercial power supply to the output power of the Inverter.
Program a sequence to input the run command and speed search command simultaneously or the run
command after the speed search command. The speed search command will be ignored if the run com-
mand is input earlier than the speed search command.
