 Offsets (C31, C36, C41, C74)
C31, C36, C41 or C74 configures an offset for an analog voltage/current input. The offset also applies to signals
sent from the external equipment.
• Data setting range: -5.0 to +5.0(%)
 Filters (C33, C38, C43, C76)
C33, C38, C43 and C76 provide the filter time constants for the voltage and current of the analog input. The larger
the time constant, the slower the response. Specify the proper filter time constant taking into account the response
speed of the machine (load). If the input voltage fluctuates due to line noises, increase the time constant.
• Data setting range: 0.00 to 5.00 (s)
