Dual Rating Selection
The WJ200 series inverter has Dual Rating, so that it can work in two different types of
load condition, Constant torque application and Variable torque application. Select
parameter depending on your application.
Func.
Name
Code
Dual Rating Selection
When changed, the rated output current and related items are changed automatically.
Differences between HD and ND are described below.
Usage
For heavy load with high torque required at start,
acceleration or deceleration
Applications
Elevators, cranes, conveyers, etc.
Rated
current
1.0A (3-phase 200V 0.1kW)
(example)
Overload current
150% 60 sec.
Initial values of HD and ND are different shown as below table. Be sure to note that
when the dual rating selection b049 is changed except H003/H203, those initial values
are also changed. (Even if currently set value is within the range of both HD and ND,
data is initialized when b049 is changed.)
