Mitsubishi Electronics FR-S500 instruction manual Always perform test operation

Explanation of functions (parameters)

CAUTION

•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. 21 and stall prevention operation level.

•When the high response current limit has been set in Pr. 21 (factory setting), torque will not be provided at the Pr. 22 setting of 170% or higher. At this time, make setting so that the high response current limit is not activated.

•In vertical lift applications, make setting so that the high response current limit is not activated. Torque may not be produced, causing a drop due to gravity.

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.
