Confirmation Before Power Up The Inverter; Changing Parameters - Hitachi NES1-004SB Quick Reference Manual

Chapter 6 Operation

6.2 Confirmation before power up the inverter

Please confirm the followings before operation.
(1) Connection of the power input (R(L1)/L1,S(L2),T(L3)/N) and motor (U(T1), V(T2), W(T3)) is correctly
connected. Otherwise there is a risk of inverter failure.
(2) There must be no mis-connection of the control wiring. Otherwise there is a risk of inverter failure.
(3) Earth grounding is properly connected. Otherwise there is a risk of electric shock.
(4) There is no ground fault other than earth grounding terminal. Otherwise there is a risk of inverter
malfunction.
(5) There must be no short circuit by the wire chip etc., There must be no tools left inside the inverter.
Otherwise there is a risk of inverter failure.
(6) There must be no short circuit or ground fault at the output side. Otherwise there is a risk of inverter
failure.
(7) Front cover must be closed. When using the RS422/RS485 port, please use to open the window of
the front cover. Otherwise there is a risk of electric shock.

6.3 Changing parameters

One of the following is required when changing parameters on NE-S1 series inverters.
(1) Dedicated operator (NES1-OP)
The operator (NES1-OP) is used with integration onto the inverter. It is not possible to use the
operator external with cable.
(2) Digital operator (OPE-SRmini,OPE-S/SR/SBK)
Digital operator can be used with connector cable (ICS-1,3) and connected to the RS422/RS485 port
(RJ45) in the inverter. Turn the changeover switch to the operator side (OFF side) in that case. Refer
to the manual for each operator for the detailed information.
(3) 5-line LCD operator (WOP)
WOP having serial number of "16918938000081" or later (2011/07 production) is applied to NE-S1
series inverter. (English only)
WOP can be used with connector cable (ICS-1,3) and connected to the RS422/RS485 port (RJ45) in
the inverter. Turn the changeover switch to the operator side (OFF side) in that case. Refer to the
manual for WOP for the detailed information.
(4) PC programming tool (ProDriveNext)
ProDriveNext Version "1.2.33.010" and later is applied to the NE-S1 series inverter.
PC can be used with connector cable and connected to the RS422/RS485 port (RJ45) in the inverter.
Turn the changeover switch to the operator side (OFF side) in that case. Refer to the manual for
ProDriveNext for the detailed information.
It is necessary to turn power off to store the changed data.
