The electrospindle
overheats:
Insufficient cooling:  Check the specifications of the system in
section 4.7 “Cooler specifications and
hydraulic connections”;
 Check the integrity and efficiency of the
cooling circuit.
Machining is too
heavy:
 Lighten the machining.
The inverter
parameters are
incorrect:
 Check the parameters on the electrospindle
plate in chapter 2 “Technical Specifications”
(in the paragraph relating to your model).
Performance lower
than specifications:
The inverter
parameters are
incorrect:
 Check the parameters on the electrospindle
plate in chapter 2 “Technical Specifications”
(in the paragraph relating to your model).
Electrospindle
vibrates:
The tool holder is not
balanced:
 Choose a tool holder according to the
indications described in section 6.5.1 “Tool
holder cone”.
The tool is not
balanced:
 Choose and use the tool as shown in
section 6.6 “Tool”.
Dirt between the tool
holder cone and
shaft-spindle:
 Remove the macroscopic impurities and
clean as described in section 7
“Programmed maintenance”.
The inverter
parameters are
incorrect:
 Check the parameters on the electrospindle
plate in chapter 2 “Technical Specifications”
(in the paragraph relating to your model).
Machining is too
heavy:
 Lighten the machining.
Fixing screws loose:
 Tighten the fixing screws:
Bearings damaged:
 Contact the manufacturer's assistance
service.
