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.
