Commissioning
The tolerant encoder monitoring is commissioned using parameters p0437 and r0459.
r0458.12 = 1 indicates whether your hardware supports the expanded encoder properties.
Note
• You can only parameterize the tolerant encoder monitoring functions when
• The functions can only be parameterized using the expert list of STARTER.
• The functions described in the following apply to SMC30 modules and to Control Units
6.18.1

Encoder track monitoring

For squarewave encoders with push-pull signals, this function monitors encoder tracks
A/B ↔ -A/B, as well as R ↔ -R. The encoder track monitoring monitors the most important
properties of the signals (amplitude, offset, phase position).
