When the drive/inverter unit generates a fault indication because of STO activation, you
must reset the drive/inverter unit before you can restart the drive.
Note: You can also configure the FSO module so that it sends a fault to the drive each time
it activates the drive STO function. See parameter FSOGEN.61 .
Motor overtemperature indication
There are two ways to configure the motor overtemperature indication.
Example 1
The ACS880 primary control program has two separate temperature monitoring functions.
In this example, one of these functions (
External event 1 ) is configured to monitor digital
input DI6. When off (0), the function triggers the user-selected indication and shows the
user-defined message. To configure the motor overtemperature indication in the drive:
1. Select the digital input which shows the status of the external event: set parameter
31.01 External event 1 source to DI6 . You can also use another digital input.
2. Select the type of the External event 1 : set parameter 31.02 External event 1 type to
Fault , Warning or Warning/Fault . If you set this parameter to Fault , the drive trips due
to overtemperature and you must reset the drive with a manual reset command before
you can restart the drive.
3. If necessary, edit the indication message. You can use the control panel or Drive
composer PC tool to edit messages.
Example 2
In this example, the motor temperature is read from digital input DI6.
1. Select PTC DI6 as the source of the temperature with parameter 35.11 Temperature 1
source . Use the same setting also with Pt100 sensors.
2. By default, an excessive temperature will generate a warning. If you want a fault instead,
set parameter
35.12 Temperature 1 fault limit to 4000 ohm .
3. If necessary, edit the indication message. You can use the control panel or Drive
composer PC tool to edit messages.

31.11 Fault reset selection
Select the correct source of an external fault reset signal with parameter 31.11 Fault reset
selection .
￭ Other recommended settings
ABB recommends that you also set these parameters to improve the safety of the application:
• minimum and maximum speeds (parameter group 30)
• maximum current, power and torque (group 30)
• acceleration and deceleration times
• stall protection (parameters 31.24…31.28 )
• motor load curve (parameters 35.50…35.55 )
• motor cable protection (parameters 35.60…35.62 )
For more information, see the drive firmware manual.
