5.4 Details of Function Codes
5-216
Offset (C31, C36, C41)
Offset can be set to the analog input voltage and current. The offset also applies to signals sent from the
external equipment.
Filter (C33, C38, C43)
Filter time constant can be set to analog input voltage/current. Choose appropriate values for the time
constants considering the response speed of the machinery system, as large time constants slow down the
response. If the input voltage fluctuates because of noise, specify large time constants.
Polarity selection (C35, C45)
Input range of analog input voltage can be set.
