Please confirm the Software Parameters for that.As we are unable to use Push Button in PowerFlex4M Series Drive for Speed reference. Please update Kind Regard Shashi Bhushan Chauhan [/INST] You may use the MOP function un PowerFlex 40. Param. P038 should be set to 1 - Internal FreqParam. A069 will act as MOP frequency reference Then you may use two Digital Inputs on the terminal as MOP increment and MOP decrement; just configure the related A051-A054 parameters to MOP Up and MOP Down. Reference is the PF40 User Manual and Aid 24194 Hope this helps… - fuzzy logic \\n </s>
