Current Limit Function

If the output current reaches the overcurrent stall level (OCS level) during
overload operation, the frequency will be automatically reduced. When the
load recovers to normal level, the frequency will be automatically restored to
the original setting and the operation will continue. This function is effective for
preventing overcurrent trips in sticky material crushing machines.
When the function becomes valid/invalid and the output current reaches the
overcurrent stall level, deceleration time will be automatically set to lower the
frequency.
The operation level (overcurrent stall level) can be set with the parameter
"P021: OCS Level".
Data setting range (s) 00·0.1 to 9.9
* "00" corresponds to a setting without current limit.
・Overcurrent trip prevention function operates regardless of the setting of the
parameter "P018: Overcurrent Stall Prevention Function" after the parameter
"P020: Current Limit Function" is set.
Related parameters: P018, P021
