Current Limit Function (Parameter P22); Start Mode (Parameter P23) - Panasonic AAD03011 Instruction Manual

[Parameter P18: Skip frequency 1 setting]
[Parameter P19: Skip frequency 2 setting]
[Parameter P20: Skip frequency 3 setting]
Data setting 000 0.5 to 250 ("000" is set when
range(Hz) the skip frequency is to be disabled.)
[Parameter P21: Skip frequency band width setting]
Data setting 0 1 to 10 ("000" is set when the skip
range(Hz) function is to be disabled.)
CURRENT LIMIT FUNCTION(Parameter P22)
If the output current reaches the overcurrent stall level due to an overload operation,
the frequency is automatically reduced. When the load returns to the correct level,
the frequency is automatically returned to the original setting, and the operation
is continued. This function is effective for preventing overcurrent trips in machines
that knead glutinous materials, etc.
The function's validity and the deceleration time for automatically lowering the frequency
when the output current reaches the overcurrent stall level are set with this parameter.
The operation level(overcurrent stall level) can be set with parameter P33(OCS level).

START MODE(Parameter P23)
Caution
Depending on the start mode, if the run signal is ON and the power
is turned ON or the power is restored after a power failure, the unit
may start(restart) suddenly. Keep out of the machine.
Design the machine so that personal safety can
be ensured even if the unit starts suddenly.
Failure to do so could lead to injury.
