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
settings (page 37).

Description
Default value
P.14.5.1 - 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).
Eme ramp stop (Off3) Selects the way the motor is stopped when an emergency
stop command is received.
P.14.5.1 Selects the source of the emergency stop signal. In this case,
the source is DIO2 of the FIO module.
P.14.5.0 Selects the source of external event 1. In this case, the
source is DIO1 of the FIO module.
Warning/Fault Selects the type of external event 2.
Warning/Warning Selects which indications are given when the Safe torque off
(STO) function is activated. Warning/Warning is the recom-
mended setting.
Value Description
User-defined 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 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 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 Defines the maximum motor frequency used in the applica-
tion. Set this parameter if you use the frequency control
mode.
1) Description
Default value
Stop and warning Selects the way the supply unit is stopped when an emer-
gency stop command is received.
DIIL Selects the source of the emergency stop signal. This para-
meter cannot be changed while the supply unit is running.
