REMARKS
When the fast response current limit is set in Pr. 21 "stall prevention function selection"
(factory setting), do not set any value above 140% in Pr. 22. The torque will not be developed
by doing so.
If the Pr. 22 value is set to higher than 140%, make setting in Pr. 21 to disable the high
response current limit.
In vertical lift applications, make setting so the fast response current limit is not activated.
Torque may not be produced, causing a drop due to gravity.
CAUTION
Do not set a small value as the stall prevention operation current. Otherwise,
torque generated will reduce.
Test operation must be performed.
Stall prevention operation during acceleration may increase the acceleration
time.
Stall prevention operation during constant speed may change the speed
suddenly.
Stall prevention operation during deceleration may increase the deceleration
time, increasing the deceleration distance.
