Motor Overtemperature Indication; 31.11 Fault Reset Selection; Other Recommended Settings - ABB ACS880 Series User Manual

42 Parameter settings
• Fault/Fault: This generates a fault in the drive/inverter unit when STO is activated.
• Fault/Warning: This generates a fault in the drive/inverter unit when the drive is running
and warning when the drive is stopped.
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.
The default values set for the options at the factory:
• option +L513+Q971 (PTC relays, with or without an FSO module): Warning/Warning
• option +L514+Q971 (Pt100 relays, with or without an FSO module): Fault/Fault.

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.

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
