Error Detection/Diagnostics

Parameter assignment error
Parameter assignment error
Causes:
The 1PosSSI/Analog cannot identify existing
•
parameters as its own.
The slot of the 1PosSSI/Analog you have configured
•
does not match the setup.
Impermissible value for parameter for number of
•
increments.
Impermissible value for parameter for number of
•
rotations.
Number of increments * number of rotations is
•
greater than 4096x4096.
What to Do:
Check the configuration, physical setup and
•
parameter assignment.
External Errors
Short circuit of the sensor supply
Causes:
Short circuit of the encoder supply made available at
•
terminals 2 and 10
What to Do:
Check the wiring and correct the short circuit.
•
Acknowledge the error with the EXTF_ACK control
•
bit.

6.6 Functions of the 1PosSSI/Analog
Response of the 1PosSSI/Analog
The 1PosSSI/Analog is not assigned parameters and cannot
•
execute its functions.
Generate channel-specific diagnostics
•
Response of the 1PosSSI/Analog
The current MODEs relative positioning and absolute
•
positioning are stopped; it is not possible to start a new run
in these MODEs.
– Analog output QV+ is set to 0 V
– Digital output OUT:
If the direction is assigned parameters for the DO
function, the digital output OUT=0 is set
– Feedback bit POS_ERR = 1
– Feedback bit POS_DONE = 0
Feedback bit ERR_ENCODER=1
•
Feedback bit SYNC = 0
•
Generate channel-specific diagnostics
•
Waits for error acknowledgment EXTF_ACK
•
Inching MODE is not affected by this error.
