3.3.6 Reading alarm information--"Alarm Information"
Menu #6 "Alarm information" in Programming mode shows the cause of the past 4 alarms as alarm
codes. Further, it is also possible to display alarm information that indicates the status of the inverter
when the alarm occurred. Table 3.13 shows the contents of the alarm information and Figure 3.10
shows the status transition of the alarm information.
Table 3.13 Alarm Information Contents

Display contents Description
6_00
Output frequency Output frequency before slip compensation
6_01
Output current Present output current
6_02
Output voltage Present output voltage
6_03
Calculated torque Calculated motor output torque
6_04
Reference frequency Present reference frequency
6_05
Rotational direction This shows the rotational direction of a run command being
output.
f
: forward;
r
: reverse; – – – –: stop
6_06
Running status This shows the running status as a hexadecimal display. Refer
to Displaying running status
in Section 3.3.3 "Monitoring the
running status."
6_07
Accumulated
running time
Shows the cumulative power-ON time of the inverter.
Unit: thousands of hours. When the total ON time is less than
10,000 hours (display: 0.001 to 9.999), it is possible to check
data in hourly units. When the total time is 10,000 hours or
more (display: 10.00 to 65.53), the display will change to units
of 10 hours. When the total time exceeds 65,535 hours, the
display returns to 0 and the count will start again.
6_08
No. of startups The motor run times (the number of times the inverter run
command is set to ON) are calculated and displayed.
1.000 indicates 1,000 times. When any number from 0.001 to
9.999 is displayed, the display increases by 0.001 per startup,
and when any number from 10.00 to 65.53 is displayed, the
display increases by 0.01 every 10 startups.
6_09
DC link bus voltage Shows the DC link bus voltage of the inverter's main circuit.
Unit: V (volts)
6_11
Max. temperature of
heat sink
Shows the maximum temperature of the heat sink.
Unit: ºC
6_12
Terminal I/O signal
status (displayed
with the ON/OFF of
LED segments)
6_13
Terminal input signal
status (in
hexadecimal format)
6_14
Terminal output
signal status (in
hexadecimal display)
Shows the ON/OFF status of the digital I/O terminals. Refer to
Section 3.3.4 "[1] Displaying control I/O signal terminals" for
details.
6_15
No. of consecutive
occurrences
This is the number of times the same alarm has occurred
consecutively.
6_16
Overlapping alarm 1 Simultaneously occurring alarm codes (1)
(– – – – is displayed if no alarms have occurred.)
