Position monitoring
STX
Initial state STX
= 0
The signal is set under the following conditions:
–
STV = 1
–
AND the value (standstill position / actual position) is within the positioning
window.
The standstill position is the sampled actual position at the time of the rising edge
of STV (0

–
OR the value (standstill position / actual position) is outside the positioning
window.

Speed monitoring
STV
Initial state STV
= 0
The STV signal is set under the following conditions:
–
The actual speed value falls below the threshold value
–
AND the value falls below the threshold value for longer than the damping
time.
