ABB ACS255 - Read Only Status Parameters

41
9.3. Read Only Status parameters
9.3.1. Read Only Status parameter access and navigation.
The user must be in the Long Parameter group to gain access to the Read only status parameters. See section 9.1.1 for how to navigate to the
long parameter group.
In the Long Parameter Group when the user scrolls to parameter “0000”, pressing will display “0104”, the User can then scroll to the
required Read only status parameter (as listed in the table above). Pressing once more will then display the value of that particular Read
only status parameter.
For those parameters which have multiple values (e.g. software ID parameter 3301), pressing the and keys will display the different
values within that parameter.
Pressing returns to the next level up. If is then pressed again (without pressing or ), the display changes to the next level up
(main parameter level, i.e. Parameter “0000”).
The following table includes the descriptions of all Read Only status parameters.

Name/Value
Description
01 OPERATING DATA
Basic signals for monitoring the drive (read-only).
For selection of an actual signal to be displayed on the control panel, see parameter 3405 DISPLAY
SCALING SOURCE.
0102

0135
FIELDBUS COMMUNICATION
SPEED REFERENCE
Displays the setpoint being received by the drive from the currently active Fieldbus interface in Hz.
0140
DRIVE LIFETIME OPERATING
TIME
Displays the total operating time of the drive. The first value shown is the number of hours. Pressing
the Up key will display the minutes and seconds. (HH:MM:SS)
0141

HEATSINK TEMPERATURE
ABOVE 80°C
Displays the amount of time in hours and minutes that the ACS255 has operated for during its lifetime
with a heatsink temperature in excess of 80°C. This parameter is used by the ACS255 for various
internal protection and monitoring functions. (HH:MM:SS)
