Note: ACS880 primary control program controls the inverter unit by default. There are
dedicated control units for the supply and inverter units.
The parameters are set at the factory. The supply unit parameter settings in the ACS880
supply control programs:
• parameter 121.05 Emergency stop source is set to value Inactive.

Value Description
User-defined In speed control mode, this parameter defines the decelera-
tion rate for emergency stop Off3 as the time it would take
for the speed to decrease from the value of parameter 46.01
Speed scaling to zero. This also applies to torque control
because the drive switches to speed control on receiving an
emergency stop Off3 command. In frequency control mode,
this parameter specifies the time it would take for the fre-
quency to decrease from the value of 46.02 Frequency
scaling to zero.
User-defined Selects the maximum speed value used to define the initial
speed value that defines the deceleration ramp rate. Set this
parameter if you use the speed control mode or torque control
mode.
User-defined Selects the maximum frequency value used to define the
initial frequency value that defines the deceleration ramp
rate. Set this parameter if you use the frequency control
mode.
