Высокопроизводительный инвертор частоты векторного управления серии SD5000

Function

Describle

Rapid current limit

It helps to avoid frequent occurrence of over current faults of the AC drive.

Multi-motor switchover

Two motors can be switched over via two groups of motor parameters.

Restoring user parameters

It allows you to save or restore the parameters set by yourself.

Higher-accuracy AI/AO

The AI/AO accuracy can reach almost 20 mv via factory correction or on-site correction.

Operation selection at fault occurrence

You can select the reaction of the AC drive to a fault occurring, based on their actual need.

The reactions are as below: • Coast to stop• Decelerate to stop• Continue to run.You can also select the frequency at which the AC drive continues to run.

PID parameters switchover

Two groups of PID parameters can be switched over via terminals or can be automaticall

switched over according to deviation.

PID feedback loss detection

The PID feedback loss value can be set to realize PID protection.

DI/DOpositive and negative logic

You can set DI/DO positive and negative logic by yourself

DI/DO response delay

You can set DI/DO response delay time.

Power dip ride through

It ensures that the AC drive continues to run for a short time when an instantaneous powe failure or sudden voltage reduction occurs.

Timing operation

The AC drive supports timing operation for 6500 minutes at maximum.
