3.3.10 Stall prevention function and current limit function
(Pr. 21, Pr. 22)
You can make setting to disable stall prevention caused by overcurrent and to
prevent the inverter from resulting in an overcurrent trip if an excessive current
occurs due to sudden load variation or ON-OFF, etc. in the output side of the
running inverter.
• Stall prevention
If the current exceeds the limit value, the output frequency of the inverter is
automatically varied to reduce the current.
• Fast-response current limit
If the current exceeds the limit value, the output of the inverter is shut off to
prevent an overcurrent.
