Table 5-7: Stall Prevention Accel Selection
The stall prevention/current limit level during acceleration is set as a percentage of
VFD
rated current. Setting
L03.01 = 00 disables current limit during acceleration. During acceleration, if the output current exceeds this
current limit level (L03.02), acceleration stops and frequency is maintained. When the output current decreases
below this current level (L03.02), acceleration restarts.

Setting
Description
00 Disable
Stall prevention/current limit during acceleration is disabled. The VFD increases the output
frequency at the set acceleration rate. If the acceleration rate is too fast for the load
condition, the VFD 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.
