n Unbundle the FeedbackTo unbundle the feedback (PI FEEDBACK) for monitoring in degrees Fahrenheit:New Intercept = 30New Slope = (Desired Range) x (Slope of Existing Point)(Range of Existing Point)New Slope = (250 - 30) °F x (0.01)(100 - 0)% = 0.022Note: 1. Desired Range = Range Maximum – Range Minimum2. Range of Existing Point = Existing Range Maximum – Existing Range Minimumu Other FunctionalitiesEnable the following functions during start-up of the drive:Enable the Drive to RunRUN ENABLE (Point 35) can be commanded to require the drive to have a physical input (Terminal S3) set before the drivecan run. This works in conjunction with CMD RUN.STOP (Point 24) or the CMD REV.STOP (Point 22). If RUN ENABLE(Point 35) is commanded ON then terminal S3 needs to be on and CMD RUN.STOP (Point 24) or CMD REV.STOP (point22) needs to be commanded ON for the drive to run. If, on the other hand, RUN ENABLE (Point 35) is commanded OFF,then to run the drive CMD RUN.STOP (Point 24) or CMD REV.STOP (Point 22), is the only point that needs to be commandedON.Start and Stop the DriveCMD RUN.STOP (Point 24) can be commanded to run the drive in the forward direction. STOP.RUN (Point 23) shows thecurrent status of the drive.Change DirectionsCMD REV.STOP (Point 22) can be commanded to run the drive in the reverse direction. FWD.REV (Point 21) shows thecurrent direction of the drive rotation.NOTICE: Damage to Equipment. Improper drive direction may damage HVAC equipment if parameter b1-04, Reverse Enable, is improperlyset (b1-04 = 0).Lock the Drive PanelLocking the panel prevents the user from using the HAND and OFF keys locally at the drive panel. LOCK PANEL (Point 33)can be commanded to lock and unlock the panel.Digital OutputsMULTI OUT 1 (Point 40), MULTI OUT 2 (Point 41), and MULTI OUT 3 (Point 42) are physical digital outputs on the drive.Their purpose depends on how the drive has been set-up. The drive can be programmed so that these points can display variouslimits, warnings, and status conditions. Some examples include frequency limit, over current, and motor over temperaturefault.Loop GainPID P GAIN (Point 63) and PID I TIME (Point 64) are the gain and integral time parameters similar to the P and I gains inthe APOGEE FLN Terminal Equipment Controllers. The PI loop of the drive is structured differently than the Siemens loop,so there is not a one-to-one correspondence between the gains.Reading and Resetting FaultsOK.FAULT (Point 93) shows the current status of the drive. FAULT CODE (Point 17) contains the code for the most currentfault. LST FLT CODE (Point 66) contains the code for the previous fault. See table below for descriptions of the fault codes.The drive can be reset back to OK mode by commanding RESET FAULT (Point 94) to RESET.C.4 Slope and Intercept Conversion274 YASKAWA SIEP YAIZ1U 03B YASKAWA AC Drive – Z1000 Programming Manual
