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. In vertical lift applications, make setting so the fast-response current limit is not cativated. Torque
may not be produced, causing a drop due to gravity.
4. At the setting of "101", the fast-response current limit can be disabled in the driving mode as
compared to the setting of "100".
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.
