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.)
3: At the setting of "101", the fast-response current limit can be disabled in the driving mode as
compared to the setting of "100".
