Figure 4-4 Energy Saving Mode
Function
Energy saving mode extends the function of the PID controller.
This enables the motor to be operated for a defined period of time with a minimum
frequency and to switch it off afterwards. If the re-start frequency is reached, the
motor is automatically re-started again. Energy saving mode is independent of the
Motor Staging Function. It is possible to combine Motor Staging and Energy Saving
Mode
.
For additional settings please refer to the parameter list P2390 and
following.
