AWARENESS
Recuperation braking S
In case of recuperation, if capacitor has filled than energy flows into mains from
motor in generator running. Since machine tools have connected in common mains
with another consumers, they receive the generated energy so electricity meter ro-
tates slower.
High capacity capacitor S
Motor will be in generator running in braking, so energy flows to the servo drive, at
first, it fills the capacitor
Electronic gearbox O
The electronic gearbox is cheaper than the mechanical construction and it has
lower current drain than a high power motor without gearbox. The users are al-
ways short of power and improving mains is very expensive. Furthermore it requires
smaller transistors, less capacitors, so the electronics is also cheaper.
Drain heat out from electric cabinet
produced by servo drives
S
Servo drives produce the most heat inside the electric cabinet. If this heat is drained
out from electric cabinet so it does not stoke the electric cabinet than it does not re-
quire energy for cooling electronics.
Switch off fans O
Measure temperature of electric cabinet and cooling ribs and stop fans if possible
No undercooling
Decreased motor inertia S Less inertia = lower power requirement= lower loss
Modern power switches S
Minimal loss
Minimal heat production
Thin grease lubrication O
Does not pollute coolant water
Does not pollute environment
