Precision
The achievable machining precision of the motor spindle is influenced by:
● The stiffness of the system (housing, bearings, spindle)
● The smooth running properties of the motor spindle
● The closed-loop control technology and the encoder resolution
The spindle manufacturer is responsible for the achieved precision.
Static charging
WARNING
Electric shock caused by static charging of the rotor
The rotor can be statically charged at higher speeds depending on the mechanical
spindle design as well as the properties of the spindle bearings (e.g. grease and
minimum oil lubrication). These could cause you to suffer an electric shock if you touch
it.
• If ceramic bearings are used, avoid voltage discharges from the shaft to the sensor
housing caused by grounding the motor shaft.
Closed loop control
The determining factors of closed-loop control include:
● the number of encoder signals per spindle revolution
● the precision achieved when mounting and adjusting the encoder system
● the interpolation of encoder signals
● the sampling time of the current and speed controller
System requirements for the closed-control
Ensure the following requirements:
● Open-loop and closed-loop control modules
– SINUMERIK 840D sl
– SINAMICS S120
● Hollow-shaft measuring system
