Zero Mark Tolerance - Siemens Sinamics S120 Function Manual

Commissioning
The following parameters must be set as precondition for track monitoring:
● p0404.3 = 1 switches to the squarewave encoder
● p0405.0 = 1 sets the signal to bipolar
Set p0405.2 = 1 to activate track monitoring.
If you selected your encoder from the list of parameter p0400, then the values above are
pre-selected and cannot be changed (also refer to the information on p0400 in the
SINAMICS S120/S150 List Manual).
Deactivating track monitoring
If encoder track monitoring is activated, you can deactivate the function by setting
p0437.26 = 1.
Evaluating messages
All of the track monitoring functions can be individually evaluated. You can use both HTL as
well as TTL encoders.
If a fault is detected, then fault F3x117
value bit-coded.
Note
For modules CU310-2, CUA32, D410-2 and SMC30 (only order numbers
6SL3055-0AA00-5CA0 and 6SL3055-0AA00-5CA1) there is only a general signal. If you
connect a squarewave encoder without R track to one of these modules, then if track
monitoring is activated, fault F3x117
To avoid this fault, at the encoder connection, you must connect the "ground encoder
supply" (pin 7) with the "reference signal R" (pin 10), as well as the "encoder supply" (pin 4)
with the "inverse reference signal R" (pin 11).

Zero mark tolerance

This function allows individual faults to be tolerated regarding the number of encoder pulses
between two zero marks.
Commissioning
Set parameter p0430.21 = 1 to activate the "zero mark tolerance" function.
