Faults, alarms, diagnosis - Basic unit control bits
-818 -
Basic unit control bits
n540.01 ... .40 = Central diagnostic parameters for positioning
- n540.02 = Effective position setpoint (acc. to rotary-axis function etc.)
- n540.03 = Position actual values from position sensing system
- n540.05 = Following error
- n540.06 = Following error - current limit (= MD15 during travel, = MD14 at a standstill)
- n540.07 = Following error - fault (following distance with correct sign when A140, A141)
- n540.08 = Remaining distance [LU]
- n540.10 = Current speed setpoint with override included in the calculation
- n540.26...33 = Position alarm memory (n540.26= Latest position alarm, = 0, if there is no current
position alarm)
Faults, alarms, diagnosis
<1> Acknowledgement possible via PMU, binector and serial interface, not via OP1S
Position alarm
Basic unit control and status bits used by the operating-mode manager and the operating modes:
ACK_F Acknowledge fault (ACKnowl. Fault)
ENC Enable controller (ENable Controller)
OFF3 OFF3
OFF2 OFF2
OFF1 OFF1

F063 = Technology option disabled; see [800]
n591 Current positioning fault message
[WARN_NO]
A129 ... A255
For example:
- A130...134 = Operating condition is missing (OFF1/2/3, inverter enable, "No fault" etc.)
- A135 = Position actual value not O.K. [815.3]
- A140 = Following error, standstill > MD14 (see also n540.07; Standstill means
"Position setpoint = 0", Axis may still be rotating!)
- A141 = Following error, moving > MD15 (see also MD43 and n540.07)
- A142 = Destination reached, axis stationary - Monitoring system activated (see MD16, MD17)
- A195,196, 227, 228 = Software limit-switch approached
