Overload capacity :
Heavy duty operation: 150% of rated current for 60 sec.
Normal duty operation: 110% of rated current for 60 sec
Booster Pump: :
It is used when a single drive is used to control multiple motors in pump systems, by default 4 Pumps can be controlled & Max upto 8 pumps can be controlled.
In the centrifugal fan and pump, PID control is provided as a standard function in order to maintain a constant pressure, flow or level.
Where external or cascaded PID control is required, the built-in dual PID algorithm of the Ex2000 can be utilised to satisfy various system requirements.
Sleep & Wake Function :
It automatically switches OFF Drive during user-programmed low- load conditions and then to start-up again when process demand increases.
It helps eliminate unnecessary operation at idle speeds, thus saving wear and tear, as well as energy.
PID Control
KEB :
During power dips or momentary power outage, the drive’s output can be maintained by utilising the residual mechanical energy in the load as a regenerative source.
The duration of the power-dip ride-through depends on the load characteristics.
Pre Heat Function :
It allows the drive to maintain residual heat in the motor, which helps eliminate condensation in damp conditions when the motor is not in use.
In the drive, an adjustable, low-level DC current is applied to the stator windings either continuously or on a duty cycle basis.
Automatic Energy Saving :
Load change may incur energy losses. But the optimised flux control of the Ex2000 results in more outstanding energy-saving.
Removable Terminal Block :
In case of AC Drive failure, control card of the existing drive can be replaced to new drive with wiring.
Reduces the downtime of AC Drive replacement
