(H) Protective function parameter
350
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 fault output " " (stop due to stall prevention) is displayed, and operation
stops.
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.
