Energy-saving function tailored to system, application
Variety of functions
● Check the energy saving effect at a glance
- ● You can check the energy saving effect on the energy saving monitor.
- ● The measured output power amount can be output in pulses.
● Reduce power consumption during standby
- ● Control circuits other than those for power-related parts can be operated with 24 VDC power supplied from an external power source.
Since the control circuit can use the external 24 VDC, other power control circuits can stay OFF while no driving is required, and that saves the standby energy. - ● By turning the cooling fan ON/OFF based on the inverter status, wasteful power consumption during stoppages can be reduced.
● Save energy with Optimum excitation control
The excitation current is constantly adjusted to drive the motor in the most efficient method which leads to energy saving.
For example, with optimum excitation control with motor load torque of 10% when using the SF-JR, motor efficiency has increased by approximately 15% over the previous V/F control method.
PM motor contributes to the energy saving in factories
PM motor
If the inverter is being used for an application requiring constant-torque, such as a conveyor, factory energy savings can be achieved by replacing your current induction motors with permanent magnet motors (PM motors).
(Tuning is required for an IPM motor other than MM-CF, and for the PM motors of other manufacturers.)
● Why is a PM motor so efficient?
- ● The current does not flow to the rotor (secondary side), so there is no secondary copper loss.
- ● Magnetic flux is generated by permanent magnets, so less current is required to drive a motor.
