Power and energy display

Independent of the motor control mode selected in

C00006

, the current output power and the

output energy supplied over the total operating time can be queried via the following display

parameters:

These display parameters serve to execute an energy analysis in the respective application. From

this, decisions can be derived whether a measurement for energy optimisation is economical.

• Hence, the following questions can be answered:

• Is it worth to use a regenerative module or should the energy be dissipated via a brake

resistor?

• Is it worth to use a DC-bus connection between the devices?

(Not possible with 8400 motec.)

• Does the application permit other parameter settings which contribute to energy saving (e.g.

lower speed, other ramp times, and speed/torque profiles)?

• What is the advantage of the V/f characteristic control - energy-saving (VFCplusEco)

compared to the other control modes?
