The state value can be read into the controller using the following system data:
1)
● System variable:
● NC/PLC interface:
● OPI variables:
● Drive parameters:
p5041[0...5]: Voltage threshold values, p5040: Voltage threshold values tolerance

Additional drive parameters

P5042:Transition time
The following times can be set in drive parameter p5042 for the clamped state identification:
● p5042[0]: Stabilization time for "clamped with tool"
The clamped state "clamped with tool" must be present in the spindle motor for at least the
set stabilization time before the state is signaled to the controller.
● p5042[1]: Maximum time for clamping
The transition from the "released" state to the "clamped with tool" or "clamped without tool"
state may take – as a maximum – the set time.
r5044: Speed limitation from the clamping cycle
The speed limit from p5043[6] which is active in the clamped state "clamped without tool" is
displayed in drive parameter r5044.
A value of 65535 means that the speed limit is not active.
