Select frequency command 2/1 -- Hz2/Hz1 (Function code data = 11)
Turning this terminal command ON and OFF switches the frequency command source
between frequency command 1 (F01) and frequency command 2 (C30).
 Refer to F01.
Enable DC braking -- DCBRK (Function code data = 13)
This terminal command gives the inverter a DC braking command through the inverter's
digital input.
(Requirements for DC braking must be satisfied.)
 Refer to F20 through F22.
Select torque limiter level 2/1 -- TL2/TL1 (Function code data = 14)
This terminal command switches between torque limiter 1 (F40 and F41) and torque limiter 2
(E16 and E17).
 Refer to F40 and F41.
Switch to commercial power for 50 Hz or 60 Hz -- SW50 and SW60
(Function code data = 15 and 16)
When an external sequence switches the motor drive power from the commercial line to the
inverter, the terminal command SW50 or SW60 enables the inverter to start running the motor
with the current commercial power frequency, regardless of settings of the reference/output
frequency in the inverter. A running motor driven by commercial power is carried on into
inverter operation. This command helps you smoothly switch the motor drive power source
from the commercial power to the inverter.
For details, refer to the table below, the operation scheme and an example of external
sequence and its operation time scheme on the following pages.
