Checking path measurement:
Turn drive shaft through one revolution and observe display of actual po-
sition.
A path value corresponding to the machine factor k (parameter 9 in
FB 'Init') must be displayed as the actual position. If the display is incor-
rect, recheck the calculation and entry of machine factor 'k'.
Checking the index signal IN:
This check is only necessary if the index signal (also called zero impulse)
is evaluated by the encoder to define the zero position.
Procedure:
(All the following actions are carried out manually by commands from
the commissioning program.)
1. Observe display of index position register
→
any value is dis-
played.
2. Execute the instruction 'SetIdxPos'.
→
When the next index impulse is captured, the actual position is
written in the index position register.
3. Turn the axis until the actual position is written in the index posi-
tion register.
The position must be written to the register once within an en-
coder revolution.
4. Execute the instruction "SetIdxPos" again and check whether,
during a revolution, the current position is written once only to the
register.
If the check produced another result, this may be due to the following:
•
Faulty encoder
•
Encoder signals A, B and IN are not in the order required at the H3
module’s position decoder input.
If the order of encoder signals is not known, it must be established with
the help of an oscilloscope.
