503 Coasting (COAST)
Value:
Digital (DIGITAL) [0]
Bus (BUS) [1]
Logical and (AND) [2]
★ Logical or (OR) [3]
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) [0]
Bus (BUS) [1]
Logical and (AND) [2]
★ Logical or (OR) [3]
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) [0]
Bus (BUS) [1]
Logical and (AND) [2]
★ Logical or (OR) [3]
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) [0]
Bus (BUS) [1]
Logical and (AND) [2]
★ Logical or (OR) [3]
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.
502 Data Read-Out (DATA READOUT) continued
[15] Warning parameter messages:
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 par. 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; control card, the two values are added;
Motor overload: 512
Current limit re; control card:
+ 16
Reading in par. 502, index 15: 528
[16] Alarm parameter messages:
Excess temperature, re; power section value: 16384
Ground connection value: 4096
Overvoltage value: 1024
Undervoltage value: 512
Unspecified inverter fault value: 236
Inverter overload value: 128
Motor overload value: 64
Short circuit value: 16
VLT attempts restart value: 8
Overcurrent value: 4
Trip locked value: 1
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: 256
Inverter overload:
+ 128
Reading in par. 502, index 18: 384
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: 4096
Unspecified inverter fault: 256
Trip locked
+ 1
Reading in par. 502, index 18: 4353
