2.2 Clearance control
2.2.1 Control dynamics
Closed-loop control gain Kv
The dynamic response of the closed control loop (sensor - open-loop control - axis) is
determined by the maximum closed-loop control gain Kv.
The closed-loop control gain Kv is defined as:
Clearance control characteristics
Clearance control is based on the two characteristics shown in the following diagram:
• Clearance sensor characteristic (sensor property)
• Clearance control characteristic (can be parameterized via machine data)
