FLEXIBLE
The crane control panel has more compact design with the application of the
Yaskawa Energy
-
Savings Unit. Regenerative energy that has been wasted as heat
can be returned to the power supply, which helps achieve energy savings.

Effective Use of Regenerative Energy
(Option)
Braking resistors are no longer necessary, and the size of crane control panels can be minimized by using
the Power Regenerative Converter D
1000 or the Power Regenerative Unit R1000. Energy lost as heat can
also be recovered as regenerative energy to further reduce the amount of energy used.
