Section V Parameter Function Table
41
Current limitation function can effectively restrain over-current caused by motor load
fluctuation in the process of acceleration and deceleration or constant speed operation.
This function will be good effect for V/F control mode.
Under protection of current lost- speed state, the motor speed will drop. so it is not adapted
by system which is not allowed to automatically drop speed.
In operation process, when the motor current surpass value A16 set, motor will decelerate
according to deceleration time A15 set until current below value A16 set.
In operation process, when the motor surpass value A17 set, motor will run with this speed
until current below value A17 set.
Deceleration current limitation is prior of constant speed limitation.
Output phase lose protection
N protection of phase lost
Warning and constant
running
Warning and free stopping
Grade of phase lose
protection
When ratio of unbalance 3phase output surpass A19 Grade of phase lose protection, the
inverter output phase lose protection i will action, and the system display fault PH-O.
Output frequency less than 2.00Hz, there is N output phase lose protection.
Phase lost protection grade=max current difference between phases, which will be according
to load condition.
Over torque inspected action
Warning and decelerating
stop
Warning and free stopping
Over torque inspection time
Motor output current surpass value A21 set, Over torque inspection will be force and the
system will show OL2 fault.
