text: <s>[INST] PoewrFlex700 HIM Start Problem Dear all, Q1: HIM Start ProblemI had install a Powerflex700 drive with DDC control enable. The Powerlfex700 drive config to run at Auto & Manual Mode, Digital In 1 set as Start Drive & Digital In 3 as AUTO/MANUAL Mode selection. Speed Control by Analog In 1 in 0-10V input. In AUTO mode, VFD was control by DDC via terminal input and the VFD works fine. While in Manual mode, the HIM take control by press ALT-AUTO/MAN, the HIM takeover the VFD control and can start and adjust VFD speed. However, once I push the Stop button(Which is red in color) the drive stop and cannot be start again by press the Start button(Which is green in color). I had to recycle power of the drive in-order to gain the MANUAL mode control again from the HIM. Also I had check that the HIM Stop button(Which is red in color) can stop the VFD in both MANUAL & AUTO mode. Then in-order to regain the VFD control, we had to recycle the VFD power again. Would anyone can help?? What is the problem and is there any config parameter I had to checked with?? Q2: Analog In ProblemOur DDC contractor use johnson control controller and speed control by 0-10V, during the T&C we found that the VFD cannot received the true signal. Actually when the DDC AO output 10V to VFD, we measured the VFD Analog In 1 had read only 7.4V?? Is that the problem of Impedence? Any thing we can do to solve it? Q3: HIM Frequency Display Minus Sign Problem My VFD was configured to run in reverse direction in order to get the Motor Runs in correction direction. Howeve the frequency display in HIM with minus sign and how can I remove it?? Any idea or suggestion?? Thousand thanks for kindly assistance in advanced. [/INST] A1. Please read the note on the bottom of page 1-23Important ; Progamming Inputs for 2 wire control deactivates all HIM Start buttons unless parameter 192, [ save HIM Ref ], bit 1 [ Manual Mode ]=1.This will allow HIM to control Start and Jog.You will need to remove the run input before selecting Manual control. A2. you could adjust the min/ max speed required to match the 0-7.5 signal \\n </s>
