Handling Robot
Situation:
The robot drives 12 cycles/min with a traverse path
of 6.5 m and a power consumption of 10.7 kW.
Problem:
Short cycles and big masses lead to excessive stress of the electronic drive unit and thus to unplanned outages.
Intention:
Raising the dynamics of the robot
thus achieving higher cycle rates with reduced energy consumption.
Solution:
> Use of 3 DES3.0 via “Plug&Play”: Stabilizing the
DC link by storing brake energy and
providing it again once needed
2 DES3.0 parallel for the linear drive axis
1 DES3.0 for the robot axis
Results:
1. Increasing cycles from 12 to 15/min:
raise in productivity by 25%
2. Lowering the power consumption to 8 kW:
energy savings of more than 25%
3. Longer service life of the electronic drive unit
