Irdy Old/New Spec. Selection - Hitachi WJ200-001S Instruction Manual

Electronic Thermal Accumulation Gain
(2)
Only for accumulation for motor electronic thermal protection, value to accumulate is multiplied with
electronic thermal accumulation gain (b913) instead of standard value. When b910=00 and common to
inverter protection, b913 is void.
Electronic Thermal Function for inverter
(3)
When electronic thermal protection subtraction selection (b910) is set other than 0, electronic
thermal protection for inverter and motor are separated. Electronic thermal protection for inverter in
this case is as described below.
Thermal protection characteristics for inverter is fixed
①
I dentical to the electronic thermal protection before Ver.3.0 with constant torque characteristics
（
with thermal level b012 with rated current
Characteristics are independent from b012-b020 setting therefore. (only for electronic thermal
②
protection for Motor is valid)
To be remarked that dual rating is considered. (it follows to CT/VT time constant)
③
Error code for inverter's electronic thermal protection is E38 (inverter thermal protection). (Error
④
code for motor electronic thermal protection remains to be E05)
E38 trip cannot be reset for 10 seconds, identical to E05.
Subtraction is invalid for inverter electronic thermal protection.
⑤
When b910=0, electronic thermal protection for inverter and motor is common. (same before
Ver.3.0)
Following Table is summery of electronic thermal protection according to b910 setting
