Power and energy display
Independent of the motor control mode selected in
, 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?
