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.
