Motor current continuous detection method
In this method, the overload is detected when the time is more than set value of Pn246 and
when the motor current more than rated value flows continuously .
For protecting the connected devices, use this method to limit the available time.
1. The motor current continuous detection method includes the operations, such as change in load or
intermittent operations in which overload protection cannot be detected.
If there is no special reason to use this method, we recommend to use electronic thermal method.
2. Even if you select both methods, and even if you perform error reset by power off for many times,
the motor temperature exceeds the allowable value.
Use I8: Free-run stop/error reset or multi function 13: Use emergency stop/error reset to perform the abnormal reset.

Pn400
Initializing the user constants
Initialize the user constants.
If you enter 1 in the number field, all user constants will be reset to initial value.
Once the number is entered, the value will be reset to 0.
Pn401
Clearing the alarm history
Initialize the alarm history.
If you enter 1 in the number field, the alarm history will be cleared.
Once the number is entered, the value will be reset to 0.
