Table 5-8: Stall Prevention Run Selection
The stall prevention/current limit level during running is set as a percentage of VFD rated current. A setting of
L03.05 = 00 disables current limit during running. During speed agree, if the output current exceeds this current
limit level (
L03.06
) during running, deceleration starts. When the output current decreases below this current limit
level (
L03.06
), acceleration starts, up to the set frequency.

Setting
Description
00 Disable
Stall prevention/current limit during running is disabled.
01 Decel Time 1
Stall prevention/current limit during running is enabled (factory default). When the VFD
output current exceeds the current limit level (L03.06) for more than 100ms during speed
agree, the output frequency is decreased according to deceleration time 1 (B05.02). This
can help prevent stalling. When the load condition is stabilized, the VFD accelerates to the
previous frequency.
02 Decel Time 2
Stall prevention/current limit running is enabled as in setting “01”, however the output
frequency is decreased according to deceleration time 2 (B05.04).
