text: <s>[INST] Voltage Signal drop at Powerflex700 drive Dear All, I had installed a Powerflex700 drive and the DDC system employs Voltage analog(0-10Vdc) control to vary the VFDspeed. However, when the system wiring completed and proceed to T&C, the voltage signal was dropped to 7.6Vdc when the DDC Analog output is 10Vdc. Therefore is there any solution to rectify the Voltage signal linear to scale so that my drive can run on full speed when 10Vdc control is received in Analog In 1?? Thousand Thanks in advance for any suggestion. Best Rgds.,Man [/INST] follow the below example.First send the maximum analog reference to the drive and look at the value in Par 016. This is the value you use in [ Analog In 1 Hi ]P320 − [Anlg In Config], bit 0 = “0” (Voltage)P090 − [Speed Ref A Sel] = “Analog In 1”P091 − [Speed Ref A Hi] = 60 HzP092 − [Speed Ref A Lo] = 0 HzP322 − [Analog In 1 Hi] = 5VP323 − [Analog In 1 Lo] = 0VThis configuration is used when the input signal is 0-5 volts. Here, minimum input (0 Volts) represents 0Hz and maximum input (5 Volts) represents 60 Hz. This allows full scale operation from a 0-5 voltsource \\n </s>
