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.
(Alarm stop display "E.OLT")
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 stall prevention operation level.
(When the output voltage reduces during stall prevention operation, an overcurrent trip will be less
liable to occur but the torque decreases. Set "0" in Pr. 154 when the torque may be reduced.)
