Description of parameters
Warning parameter messages [15]:
Frequency low re parameter 210 value: 32768
Frequency high re parameter 211 value: 16384
Current limit, re power section value: 8192
Key blocked value: 2048
Motor overload value: 1024
Inverter overload value: 512
Outside frequency range value: 256
Current higher than para. 213 value: 128
Data locked value: 64
Read only value: 32
Current limit re control card value: 16
Overvoltage value: 8
Undervoltage value: 4
Can only be changed in stop mode value: 2
Parameter limit value: 1
Usually only one warning occurs at a time, so one of
the figures in parameter 502, index 15, will show.
In the event of several simultaneous warnings, e.g.
Motor overload and Current limit, re contral card, the
two values are added:
Inverter overload 512 +
Current limit re control card 16
Reading in para. 502, index 15: 528
Alarm parameter messages [18]:
Excess temperature, re power section value: 16384
Earth connection value: 4096
Overvoltage value: 1024
Undervoltage value: 512
Unspecified inverter fault value: 256
Inverter overload value: 128
Motor overload value: 64
Short circuit value: 16
VLT attemps restart value: 8
Overcurrent value: 4
Trip locked value: 1
In contrast to warnings, alarms will always be com-
bined, i.e. at least 2 of the alarm parameters apply,
e.g. Unspecified inverter fault will usually occur with
another alarm, e.g. Inverter overload. It will give the
following reading:
Unspecified inverter fault 256 +
Inverter overload 128
Reading in para. 502, index 18: 384
In case of Short circuit, Earth connection and Excess
temperature, re power section, Trip locked will also
occur. This will give a typical reading:
Earth connection 4096 +
Unspecified inverter fault 256 +
Trip locked 1
Reading in para. 502, index 18: 4353
503 Coasting (COAST)
Value:
Digital (DIGITAL) [0]
Bus (BUS) [1]

504 Q stop (Q-STOP)
Value:
Digital (DIGITAL) [0]
Bus (BUS) [1]
Logical and (AND) [2]
