)unction Description
Multi-motor switchover
)our motors can be switched over via four groups of
motor parameters.
Restoring user parameters
It allows you to save or restore the parameters set by
yourself.
Higher-accuracy A
I/AO
The AI/AO accuracy can reach almost 20 mv via factory
correction or on-site correction.
Customized parameter
display
Yo
u can customize the parameters that need to be
displayed.
Modi¿ed parameter display You can view the modi¿ed parameters.
Operation selection at fault
occurrence
You can select the reaction of the AC drive to a fault
occurring, based on the actual need. The reactions are as
below:
Coast to stop
Decelerate to stop
Continue to run
Yo
u 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 automatically switched over according
to deviation.
PID feedback loss detection
The PID feedback loss value can be set to realize PID
protection.
DI/DO positive or negative
logic
Yo
u can set the DI/DO positive or negative logic.
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 power failure or sudden
voltage reduction occurs.
Ti
ming operation
The AC drive supports timing operation for 6500 minutes
at maximum.
User programmable function
The externally connected programmable card helps you
to realize secondary development.
Load allocation
Load allocation can be implemented between two MD380
