User Manual Chapter 7 - Parameters Description 65S.202 Ref 1 Channel (Reference 1 channel)It defines the source from where the Reference 1 is provided and controlled.For further details please refer to chapter FREQ & RAMPS, section Reference Source.S.203 Frequency ref 0 (Frequency reference 0)Digital speed reference.It is also the first digital frequency of the Multispeed selection (F.100
F.116).It is possible to set setting with positive or negative values.The polarity will determine the sense of rotation of the motor.In either polarity the setting the HW Reverse command is active (when enabled).The maximum settable value is correlated to Max ref freq (S.201).Code Name [Code] & Function Default MIN MAX Unit Variation IPAS.200 Cmd source sel [1] Terminals 1 0 4 400[2] Virtual[3] FoxLink[4] Control wordS.201 Max ref freq (****) 25 500 Hz 0.1 305S.202 Ref 1 channel [0] Null 3 0 8 307[1] Analog inp 1 (setting through I.200
