Bypass Param. screen
Bypass frequency range (Hz)
When the difference between the bypass input frequency and the rated frequency is
greater than this value, the system determines that the bypass frequency is abnormal and
that the bypass is unavailable.
The value range is ±0.5 Hz to ±6 Hz, and the default value is ±2 Hz.
Maximum bypass voltage
Upper threshold for the bypass voltage. When the difference between the bypass voltage
and the rated voltage exceeds this value, the system determines that the bypass voltage is
abnormal and that the bypass is unavailable.
−
380 V voltage level
The value can be +10%, +15% (default), +20%, or +25%.
−
400 V voltage level
The value can be +10%, +15% (default), and +20%.
−
415 V voltage level
The value can be +10% (default) or +15%.
Minimum bypass voltage
Lower threshold for the bypass voltage. When the difference between the bypass voltage
and the rated voltage exceeds this value, the system determines that the bypass voltage is
abnormal and that the bypass is unavailable. The value can be –10%, –15%, –20%
(default), –30%, –40%, –50%, or –60%.
ECO voltage range
In ECO mode, when the difference between the bypass voltage and the rated voltage is
greater than this value, the system determines that the ECO voltage is abnormal and
transfers to normal mode. The values can be 5% (default), 6%, 7%, 8%, 9%, or 10%.
BPM mode upon BPM overtemp.
This parameter specifies whether to start bypass mode if overtemperature occurs.
