NOTE: When using the Multi-speed Select settings CF1 to CF4, do not display
parameter F001 or change the value of F001 while the inverter is in Run Mode (motor
running). If it is necessary to check the value of F001 during Run Mode, lease monitor
D001 instead of F001.
HIGH VOLTAGE: When set RDY function ON, there will be a voltage appears at motor
output terminals U, V and W even if the motor is in stop mode. So never touch the
inverter power terminals even the motor is not running.
NOTE: The EMR is not programmable, but will be assigned automatically when the
hardware switch S8 is made ON. When the EMR is assigned, function assignments of
terminal 3, 4 and 5 are automatically changed as follows. Please also refer to

Input Function Summary Table
ON Adds the A145 (add frequency) value to the output
frequency
OFF Does not add the A145 value to the output frequency
ON Force inverter to use input terminals for output
frequency and Run command sources
OFF Source of output frequency set by A001 and source of
Run command set by A002 is used
ON To charge up the internal boot-strap capacitor so to
start motor immediately after the RUN command is
given.
OFF Inverter operates normal.
ON The inverter uses 2nd motor parameters for generating
frequency output to motor. The selection of 1st or 2nd
motor is available during Stop Mode or Run Mode.
OFF The inverter uses 1st (main) motor parameters for
generating frequency output to motor.
ON Inverter recognizes that the emergency signal is given,
Stop
and shuts off the output.
Refer to "Safe Stop" on page 4-32.
