PARAMETERS
Description of parameters
(6) Monitor switching with input terminal (Pr. 50, Pr. 52, Pr. 54)
Monitoring item can be switched by ON/OFF of terminals X1 and X2.
By setting 1 to 4 to the four digits of Pr. 52 (Pr. 54, Pr. 50), monitor can be switched by the terminals.
Number set in each digits represents the following monitor.
In the initial setting (1234), the monitor changes according to the input terminal status as shown below.
3.4.14 Operation selection at instantaneous power failure (Pr. 57)
If restart after instantaneous power failure is activated at the inverter side, set Pr. 57 Restart selection = "0" at the converter
side.
When Pr. 57="9999," the inverter output is stopped by the fault signal "E.IPF" from the converter even though the automatic
restart after instantaneous power failure is activated in the inverter.

CAUTION
The motor and machine will start suddenly after occurrence of an instantaneous power failure (after the reset
time has elapsed). Stay away from the motor and machine when automatic restart after instantaneous power
failure has been selected.
If the automatic restart after instantaneous power failure function has been selected, apply the CAUTION
stickers, which are supplied with the Instruction Manual of the inverter, to easily visible places.
