For parameter configuration
[bC210] to [bC225]
(Example 2)
When [bC111]=01, Inverter rated current:64A，[bC110]=64(A),
Base frequency [Hb103]=60Hz, Output frequency=2.5Hz
・In case of output frequency = 2.5Hz, the reduction scale
is x0.9, then, the inverter will trip when the output
current of 135%(=150%×0.9) flows continuously within
60s according to the curve.
(Example 3) When [bC111] = 02, and Output frequency = [bC122]
2nd motor When Intelligent Input terminal 024[SET] is enabled.

inverter sales office.
※Notes on electronic thermal function !
The SH1 is implemented with the inverter-protected
electronic thermal (not user-configurable) separately
the Electronic thermal protection for the motor.
It operates as an electronic thermal with 150% ND
rated current and the constant torque characteristics
regardless of the setting of [Ub-03] Load type selection.
(Refer to the left (Example 2) ).
Even if [Ub-03] is changed to “Low Duty (LD)” or “Very
Low Duty (VLD)”, check the carrier derating at the
“Normal Duty” rating.
In some cases, E039 Controller (inverter) overload
occurs.
For more information, Please contact your supplier or
local Hitachi inverter sales office.
