Group 04: Fault history
Code Description Range Resolution Default S
0401 LAST FAULT Fault code text 1 0
0 = Clear the fault history (on panel = NO RECORD).
n = Fault code of the last recorded fault.
• The fault code is displayed as a name. See chapter
Fault tracing on page 359 for
the fault codes and names. The fault name shown for this parameter may be shorter
than the corresponding name in the fault listing, which shows the names as they are
shown in the fault display.
0402 FAULT TIME 1 Date dd.mm.yy /
power-on days
1 0
The day on which the last fault occurred. Either as:
• A date – if real time clock is operating.
• The number of days after power on – if real time clock is not used, or was not set.
0403
FAULT TIME 2
Time hh:mm:ss 2 s 0
The time at which the last fault occurred. Either as:
• Real time, in format hh:mm:ss – if real time clock is operating.
• The time since power on (less the whole days reported in parameter
0402 FAULT
TIME 1 ), in format hh:mm:ss – if real time clock is not used, or was not set.
Format on the basic control panel: Time elapsed after power-on in 2-second ticks
(minus the whole days stated by signal
0402 FAULT TIME 1 ). 30 ticks = 60 seconds.
For example, value 514 equals 17 minutes and 8 seconds (= 514/30).
0404 SPEED AT FLT - 1 rpm 0
The motor speed (rpm) at the time the last fault occurred.
0405 FREQ AT FLT - 0.1 Hz 0.0
The frequency (Hz) at the time the last fault occurred.
0406 VOLTAGE AT FLT - 0.1 V 0.0
The DC bus voltage (V) at the time the last fault occurred.
0407
CURRENT AT FLT
- 0.1 A 0.0
The motor current (A) at the time the last fault occurred.
0408 TORQUE AT FLT - 0.1% 0.0
The motor torque (%) at the time the last fault occurred.
0409
Reserved for future use
0412 PREVIOUS FAULT 1 Fault code text 1 0
Fault code of the second last fault. Read-only
0413 PREVIOUS FAULT 2 Fault code text 1 0
Fault code of the third last fault. Read-only.
0414 DI 1-5 AT FLT
Status of digital inputs DI1...5 at the time the latest fault occurred (binary).
Example: 10000 = DI1 is on, DI2...DI5 are off.
