.
Thermal load INV [%], parameter 527:
Gives the calculated/estimated thermal load on the
frequency converter. 100% is the cut-out limit.
Digital input, parameter 528:
Gives the signal status from the 8 digital inputs
(16, 17, 18, 19, 27, 29, 32 and 33). Input 16
corresponds to the bit on the extreme left.

Inverter temperature, parameter 537:
Gives the present inverter temperature on the
frequency converter. The cut-out limit is 90-100
°C, with cut back in at 70 ± 5 °C.
Alarm word, parameter 538:
Gives in Hex which alarm is on the frequency
converter. See
Warning word, extended status
word and alarm word.
Control word, parameter 539:
Gives the present control word on the frequency
converter in Hex. See
Serial communication
in
Appendix
.
Warning word, parameter 540:
States whether there is a warning on the frequency
converter in Hex. See
Warning word, extended
status word and alarm word.
Extended status word, parameter 541:
States whether there is a warning on the frequency
converter in Hex. See
Warning word, extended
status word and alarm word.
580-582 DEFINED PARAMETERS
Value:
Read only
Function:
The three parameters hold a list of all the parameters
defined in the frequency converter. Each of the three
parameters can be read as an array by means of
the acyclical FMS
read
service with subindex 255.
It is also possible to read single elements of the
list by DP and cyclical/acyclical FMS by using the
corresponding subindex. The subindexes start at 1
and follow the order of the parameter numbers.
Each parameter holds up to 116 elements
(parameter numbers). The number of parameters
(580, 581 and 582) in use depends on the actual
frequency converter configuration.
When a 0 is returned as parameter number, the list ends.
Parameter 580-582 can only be read out via the serial
communication. No access through the LCP.
