* 4. Terminal input specifications
can be changed by analog
input specifications switchover
(Pr. 73, Pr. 267). Set the
voltage/current input switch in
the OFF position to select
voltage input (0 to 5V/0 to
10V) and ON to select current
input (0 to 20mA).
(Refer to page 155)
* 5. It is recommended to use
2W1kΩ when the
frequency setting signal is
changed frequently.
CAUTION
· To prevent a malfunction due to noise, keep the signal cables more than 10cm away from the power cables. Also separate the
main circuit wire of the input side and the output side.
· 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.
· Set the voltage/current input switch correctly. Operation with a wrong setting may cause a fault, failure or malfunction.

*1. DC reactor (FR-HEL)
Be sure to connect the DC reactor
supplied with the 01800 or more.
When a DC reactor is connected
to the 01160 or less, remove the
jumper across P1-P/+.
