No.
Selects a drive signal to be connected to relay output RO1.
In this case, the RO1 is energized by the status of DIO2 of
the FIO module (inverted value).
P.14.5.1 -
RO1 source
14.34
Selects the way the motor is stopped when an emergency
stop command is received.
Eme ramp stop (Off3)
Emergency
stop mode
21.04
Selects the source of the emergency stop signal. In this case,
the source is DIO2 of the FIO module.
P.14.5.1
Emergency
stop source
21.05
Selects the source of external event 1. In this case, the
source is DIO1 of the FIO module.
P.14.5.0
External event
2 source
31.03
Selects the type of external event 2.
Warning/Fault

31.04
Selects which indications are given when the Safe torque off
(STO) function is activated.

is the recom-
mended setting.

1) Value set by ABB at the factory for the default design.
The table that follows gives the parameters in the ACS880 primary control program that you
must set according to application requirements. Make sure that the selected values agree
with the time delay settings of the emergency stop safety relay [A61]. Refer to
Description
Value
Name
No.
Defines the zero speed limit. The motor is stopped along a
speed ramp until this limit is reached. After the zero speed
delay (parameter
21.07
, default value
0 ms
), the motor coasts
to a stop.
User-defined
Zero speed lim-
it
21.06
Defines the deceleration time for emergency stop Off3. The
deceleration time is the time it takes to decelerate the motor
from the maximum process speed defined by parameter
46.01
or
46.02
to the zero speed limit defined by parameter
21.06
.
User-defined
Emergency
stop time
23.23
Defines the maximum motor speed used in the application.
Set this parameter if you use the speed control mode or
torque control mode.
User-defined
Speed scaling
46.01
Defines the maximum motor frequency used in the applica-
tion. Set this parameter if you use the frequency control
mode.
User-defined
Frequency
scaling
46.02
The table that follows gives the parameters related to the safety function in the ACS880
supply control programs. The parameters are set at the factory.
