A liquid-cooled heat sink transfers over 80% of the heat from the drive to the coolant, giving the unit the best drive power-to-size ratio in the market, according to the manufacturer. And it is about half the size of typical air-cooled controllers. The 700L also features an active converter and line-side filters so it will perform consistently despite power dips or other power-quality issues. It also sends 480 V to the motor even when operating on 380-Vac power lines.
Instead of relying on resistor braking like most other controllers, the liquid-cooled 700L uses regenerative braking to generate electricity while braking. This electricity is put back into the system and used by other equipment.
