Easy-to-Change Cooling Fan

It is easy to change a cooling fan without
opening the cover of the drive.

DT - Delay Time

Pump Clean Operation

Scraps and deposits that get built up in impellers inside pumps, decrease the efficiency of a motor's
performance. Through consecutive FWD/REV or ACC/DEC operations, the scraps get eliminated.
This results in extension of the pump's lifespan, prevents pre-mature pump failure and ensures
energy savings. The Pump Clean mode is initiated by a remote signal, current profile or power profile.

Flange-Type Mounting
If the space is too small, a heat sink can be
installed outside the panel. This helps reduce
heat losses inside the panel.
Payback Counter (Energy Saving Display) Load Tuning
It displays energy saving information by comparing Establishes load (current and power) curves based

Device Purpose Details

To protect Always install the MCCB or MPCB on the power supply side to
MCCB or MPCB
inverter wiring protect the inverter from Short Circuit & Overload protection
Used at Input side to provide complete isolation when drive
Magnetic is switched off thus protecting the internal components.
For Isolation
Contactor Also used for preventing burning of braking resistor with
thermal feedback
To improve
Input AC or DC Use for further improving the power factor of the inverter
Inverter Power
Reactor by suppressing the harmonics from the power supply
Factor
To avoid nuisance tripping of inverter due to leakage current
To avoid nuisance
Output Reactor caused because of the capacitive effect in longer cables
tripping of inverter
between inverter & motor
Shortens the deceleration time by consuming the regenerative
Braking Resistor To stop the energy of the motor by the resistor
machine within
the preset time Used in combination with the braking resistor to reduce the
Braking Unit
deceleration time of the motor
