 Disabling the stall prevention operation and fast-response current limit
according to operating conditions (Pr.156)
• Referring to the following table, enable/disable the stall prevention operation and the fast-response current limit operation,
and also set the operation at OL signal output.

*1 When "operation stop at OL signal output" is selected, the fault output "
stops.
*2 The OL signal or E.OLT is not outputted because fast-response current limit and stall prevention are not operating.
*3 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. Set the Pr.156 and 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.
