Note 1: When "Operation not continued for OL signal output" is selected, the "E.OLT"
alarm code (stopped by stall prevention) is displayed and operation stopped.
2: If the load is heavy, the lift is predetermined, or the acceleration/deceleration
time is short, the stall prevention may be activated and the motor not
stopped in the preset acceleration/deceleration time. Therefore, set optimum
values to the Pr. 156 and stall prevention operation level.
CAUTION
Always perform test operation.
Stall prevention operation performed during acceleration may increase
the acceleration time.
Stall prevention operation performed during constant speed may cause
sudden speed changes.
Stall prevention operation performed during deceleration may increase
the deceleration time, increasing the deceleration distance.
