00 Disable See Table 5-8
01 General Purpose See Table 5-8
02 Intelligent See Table 5-8
Setting Description
00 Disable Stall prevention/current limit during acceleration is disabled. The inverter
increases the output frequency at the set acceleration rate. If the acceleration rate
is too fast for the load condition, the inverter may trip on overcurrent (OC) or
overload (OL).
01 General Purpose Stall prevention/current limit during acceleration is enabled (factory default).
The acceleration rate is automatically extended according to motor current to
prevent stalling during acceleration. The acceleration time may be longer than the
set value (B05.01).
02 Intelligent Stall prevention/current limit during acceleration is enabled with an intelligent
acceleration mode. By monitoring motor current, the acceleration is the shortest
amount of time, regardless of the set acceleration time.
