502 Data Read-Out (DATA READOUT) continued
[15] Warning parameter messages:
Frequency low re; parameter 210
Frequency high re; parameter 211
Current limit, re; power section
Key blocked
Motor overload
Inverter overload
Outside frequency range
Current higher than par. 213
Data locked
Read only
Current limit re; control card
Overvoltage
Undervoltage
Can only be changed in stop mode
Parameter limit
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; control card, the two values are added;
Motor overload:
Current limit re; control card:
Reading in par. 502, index 15:
[16] Alarm parameter messages:
Excess temperature, re; power section value: 16384
Ground connection
Overvoltage
Undervoltage
Unspecified inverter fault
Inverter overload
Motor overload
Short circuit
VLT attempts restart
Overcurrent
Trip locked
In contrast to warnings, alarms will always be combined,
i.e. at least 2 of the alarm parameters apply, e.g.
Unspecified inveter fault will usually occur with another
alarm, e.g. Inverter overload. It will give the following
reading:
Unspecified inverter fault:
Inverter overload:
Reading in par. 502, index 18:
In case of Short circuit Ground connection and Excess
temperature, re; power section, Trip locked will also occur.
This will give a typical reading:
Groung connection:
Unspecified inverter fault:
Trip locked

Figures in [ ] are used when communicating with the bus.
503 Coasting (COAST)
Value:
Digital (DIGITAL)
Bus (BUS)
Logical and (AND)
Logical or (OR)
Description:
In parameters 503 to 510 you can choose to control the
VLT adjustable frequency drive via the control unit's
terminals (digitally) and or via the bus.
When using Logical and Bus values in parameters 503-510,
the digital control terminals are either dependent on or
overruled by the bus commands.
504 Quick-Stop (Q-STOP)
Value:
Digital (DIGITAL)
Bus (BUS)
Logical and (AND)
Logical or (OR)
Description:
In parameters 503 to 510 you can choose to control the
VLT adjustable frequency drive via the control unit's
terminals (digitally) and or via the bus.
When using Logical and Bus values in parameters 503-510,
the digital control terminals are either dependent on or
overruled by the bus commands.
505 DC Brake (DC-BRAKE)
Value:
Digital (DIGITAL)
Bus (BUS)
Logical and (AND)
Logical or (OR)
Description:
In parameters 503 to 510 you can choose to control the
VLT adjustable frequency drive via the control unit's
terminals (digitally) and or via the bus.
When using Logical and Bus values in parameters 503-510,
the digital control terminals are either dependent on or
overruled by the bus commands.
506 Start (START)
Value:
Digital (DIGITAL)
Bus (BUS)
Logical and (AND)
Logical or (OR)
Description:
In parameters 503 to 510 you can choose to control the
VLT adjustable frequency drive via the control unit's
terminals (digitally) and or via the bus.
