Group 57: FSM: Inputs/Outputs
57-0
FSM: I/O - Self test error
(internal/external)
Cause:
▪ Internal error of digital inputs DIN40 ... DIN43 (detected via internal test
signals).
▪ Error at brake output at X6 (signalling, detected by test pulses).
▪ Internal error of brake output (detected via internal test signals).
▪ Internal error of digital outputs DOUT40 –DOUT42 (detected via internal test
signals).
Measure:
▪ Check the connection wiring for the digital outputs DOUT40...DOUT42
(short circuit, cross circuit, etc.).
▪ Check the connection wiring for the brake (short circuit, cross circuit, etc.).
▪ Brake connection: The error may occur with long motor cables if:
1.
The brake output X6 was configured for the brake (this is the case with
factory settings!) and
2.
A motor without a holding brake is used and the brake connection lines in
the motor cable are terminated at X6. In this case: Disconnect the brake
connection lines at X6.
▪ If there is no error in the connection wiring, there may be an internal error in
the module (check by replacing the module).
57-1
FSM: digital inputs -signal
level error
Cause:
Exceeding / violation of discrepancy time with multi-channel inputs (DIN40 ...
DIN43, two-handed control device, mode selector switch).
Measure:
▪ Check the external active and passive sensors – do they switch on two chan
-
nels and simultaneously (within the parameterised discrepancy time).
▪ Two-handed control device: Check how the device is operated by the user –
are both pushbuttons pressed within the discrepancy time? Give training if
necessary.
▪ Check the set discrepancy times – are they sufficient?
57-2
FSM: digital inputs -test
pulse error
Cause:
• One or more inputs (DIN40 ... DIN49) were configured for the analysis of
the test pulses of the outputs (DOUT40 ... DOUT42). The test pulses from
DOUTx do not arrive at DIN4x. Measure:
• Check the wiring (shorts after 0 V, 24 V, cross circuits).
• Check the assignment – correct output selected / configured for test
pulse?
