Inverter overload protection characteristics
*To protect the inverter, overload trip or overcurrent trip activate in a short period of time when output current reaches 110% or higher.
| 4) Thermal memory selection | H |
|
| At the main power off, it is selectable whether retention of electric thermal calculation values or not. | ||

|
5 | : Incase of not activated | ||
The calculated value of the electric thermal is not memorized at |
The calculated value of the electric thermal and the trip state can always be reset.
Don’t reset the unit trip state continually, it may cause the motor and the unit failure.
: In case of activated
The calculated value of the electric thermal is memorized at
The trip state can always be reset but the calculated value of the electric thermal can not be reset.
5.13 Preset-speed operation (speeds in 7 steps)
UT - UT : Preset-speed operation frequencies 1-7
•Function
A maximum of 7 speed steps can be selected just by switching an external contact signal.

[Setting method]
1)Run/stop
The starting and stopping control is done from the terminal board.
Title | Function | Adjustment range | Setting value |

Note:If speed commands (analog signal or digital input) are switched in line with
the terminal board using the frequency setting mode selection HOQF. | ⇒ See step 3) or section 5.3. |
