EzCOM
(Peer-to-Peer communication)
WJ200 supports Peer-to-Peer communication between multiple
inverters. One administrator inverter is necessary in the network, and
the other inverters act as master or slave.
Varnish coating of
internal PC board is
standard.
(Logic PCB and I / F PCB are
excluded.)

WJ200 can be used for both heavy and
normal duty. One-frame-size smaller WJ200
can be applicable to certain applications.

Sequence operation is realized by downloading to an inverter a
program created with Hitachi's EzSQ software. User program can
be compiled on EzSQ software on a PC. External components can
be simplified or eliminated, resulting in cost-savings.
Design lifetime 10 Years or more for DC bus
capacitors and cooling fan.
Cooling fan ON / OFF control function for longer
fan life.
*Ambient temperature : Average 40

C (no corrosive gases, oil mist or dust)
Design lifetime is calculated, and not guaranteed.
The cooler fan can be exchanged
without special tools.
Hitachi original PWM control method
limits motor terminal voltage to less than
twice inverter DC bus voltage.
Lower than Hitachi motor max. insulation
voltage (1,250V)
(During regeneration, the motor terminal voltage may exceed
the motor maximum insulation voltage (1,250V))
WJ200 diagnoses lifetime of DC bus capacitors
and cooling fan(s).
The WJ200 inverter has a password function to prevent changing
parameters or to hide some or all parameters.

Energy cost saving by speed reduction.
■
Daytime: Motor speed is automatically reduced to reduce demand during peak hours.
■
Nighttime: Motor speed is increased to take a advantage of off-peak power rates.

WJ200 conforms to the applicable safety standards and corresponds
to Machinery Directive of Europe. Shuts down the inverter by
hardware, bypassing the CPU, to achieve reliable safe stop function.
The safety standard can be met at a low cost.
