(H) Protective function parameter
334
PARAMETERS
 Disabling the stall prevention operation and fast-response current limit
according to operating conditions (Pr.156)
• Referring to the table below, enable/disable the stall prevention operation and the fast-response current limit operation, and
also set the operation at OL signal output.

When "operation stop at OL signal output" is selected, the inverter stops its operation at the OL signal output (stall prevention stop).

The OL signal and E.OLT are not outputted because fast-response current limit and stall prevention are not operating.

Setting values "100, 101" can be individually set for power driving and regenerative driving. The setting value "101" disables the fast-response
current limit during power driving.
NOTE
• When the load is heavy or the acceleration/deceleration time is short, stall prevention operates and acceleration/deceleration
may not be performed according to the time set. In such case, set the Pr.156 and the stall prevention operation level to the
optimum values.
• For lift applications, make settings to disable the fast-response current limit. Otherwise, the torque may be insufficient,
causing the load to drop.
