*) c = power loss into coolant; a = power loss into air; T = total power loss.
All power losses obtained using max. supply voltage, I
control mode. All power losses are worst case losses.
If some other mains voltage is used, apply the formula
NX Liquid-Cooled drive electrical output power.
If the motor is continuously (besides start and stop ramps) run at frequencies below 5 Hz, pay attention to the
drive dimensioning for low frequencies, i.e. maximum I
recommended to check the rating with your distributor or Vacon.
Drive overrating may also be necessary if the process requires high starting torque.
The voltage classes for the inverter units used in the tables above have been defined as follows:
Input 540 VDC
= Rectified 400 VAC supply
Input 675 VDC
= Rectified 500 VAC supply
The enclosure class of all inverter units is IP00.
