    Expansion Module. 12.7 DIGITAL OUTPUTS The CFW100 can activate up to three relay digital outputs (DO1 to DO3) – one with the CFW100-IOAR accessory or three with the CFW100-IOADR accessory connected to the product. The configuration of the digital output parameters is according to the detailed description below.
  • Page 97 Properties: Description: Using this parameter, it is possible to view the CFW100 digital output status. The P013 value is indicated in hexadecimal, where each bit of the number indicates the status of a digital output, that is, if BIT0 is “0”, DO1 is inactive; if BIT0 is “1”, DO1 is active, and so on, up to DO3.
  • Page 98 These parameters set the hysteresis and actuation level on the Fx output frequency signal and on the F* ramp input of the relay digital output. In this way, the relay commutation levels are “P281 + P282” and “P281 - P282”. 12-18 | CFW100 Return...
