*4 Terminal input
specifications can be
changed by analog input
specifications switchover
(Pr. 267). Set the
voltage/current input
switch in the "V" position
to select voltage input (0
to 5V/0 to10V) and "I"
(initial value) to select
current input (4 to 20mA).
*5 It is recommended to use 2W1kΩ
when the frequency setting signal
is changed frequently.
NOTE
To prevent a malfunction caused by noise, separate the signal cables more than 10cm from the power cables.
After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes
in an enclosure etc., take care not to allow chips and other foreign matter to enter the inverter.
To ensure safety, for single-phase power input specification model, connect the power input to the inverter via a
magnetic contactor and earth leakage circuit breaker or moulded case circuit breaker, and use the magnetic
contactor to switch power on-off.
The output of the single-phase power input specification is three-phase 200V.
