Parameter settings 23
Inverter units parameter settings
The inverter unit parameter setting in ACS880 primary control program:
•
parameter 31.22 STO indication run/stop is set to value Warning/Warning .
We recommend that you do not set parameter 31.22 STO indication run/stop to value 0 , 1
or 2 . This prevents the inverter units from making a fault every time the FSO module
activates the inverter units STO function.
For more information, see the firmware manual.

Safety pulse encoder parameters
The inverter unit parameter settings in ACS880 primary control program when you use a
safety pulse encoder:
•
parameter 90.41 Motor feedback selection is set to value Encoder 1 .
•
parameter 90.45 Motor feedback fault is set to value Warning .
Note : If you want that the inverter units trip on encoder faults, set this parameter to
value Fault . For more information, see the firmware manual.
•
parameter 92.21 Encoder cable fault mode is set to value A+, A1, B+,B-, Z+ , Z- .
92.02 Encoder 1 source Module 1 Sets the safety pulse encoder interface module that the
safety pulse encoder 1 is connected to.
92.10 Pulses/revolution 2048 Sets the number of HTL pulses per revolution for safety
pulse encoder 1.
Adjust the default value to meet the safety pulse encoder in
use. Make sure that the value is according to the encoder
nameplate.
92.17 Accepted pulse
freq of encoder 1
300 kHz Sets the maximum pulse frequency range of encoder 1.
Adjust the default value to meet the motor and safety pulse
encoder in use. You can use this formula to define the value:
r_max x p 10%, where
• r_max = the maximum motor speed used in the application
(or the motor nominal speed)
• ppr_enc = Pulses/revolution of the safety pulse encoder
(parameter 92.10 ).
