5-4KaVo OP 3D Vision Service Manual032-0358-EN Rev BRP Read Platform position = Reads the platforms stepper motor position.Results returned in format: OK xxxxxThe home position is the back of the gantry with a position of 1500. Front on thelarge field of view is ~70,000 and on the medium field of view it is ~79,000. Eachmillimeter of distance will move the motor 1,008 steps.RPP Read Panel Position - Reads the panel positionResults returned in format: OK n0 Error (Both limit switches are open)1 Half-Beam / Portrait mode2 Full-Beam / Landscape mode3 ErrorRR Read RotationReads the rotation position in stepper motor space.Results returned in format: OK xxxxxxOne degree of distance is approximately ~1481.50 steps in stepper motor space.Exceptions do apply, namely when moving to negative target degree locations. Thefull range of motion in motor space is 35000-733333 or in degrees -40 through 430.RX Read X-ray Setup - reads the X-ray Setup register based on the requested KVrange setting.Command syntax: RX n0 = 120 KV Range (default) 1 = 90 KV RangeResults returned in format:OK kV mA TicksPerFrame XrayOn XrayOff PanelRead PulseModeSet CommandsSP Sets platform position - Sets the counts of the platform.Command syntax: SP nn = 0 to 65000The “HP” (home platform) command moves the platform to the rear of the gantryand then sets the position to 1500. The position once moved to the rear could be“set” to 0 using this command. In general, this command is used internally by theembedded firmware.SR Sets rotation position - Sets the counts of the rotation.Command syntax: SR nn = 35,000 to 733333The “HFR” (home fast rotation) command moves the rotation to the limit switch.This location is then set to 100,000. This position, once moved, could be “set” to50,000 using this command. In general, this command is used internally by theembedded firmware.SX Set X-rayCommand syntax:SX kV mA TicksPerFrame XRayOn XRayOff PanelRead PulseMode TubeRangekV: 80 to 126 in increments of 2 onlymA: 0 = 3mA, 1 = 5mA, 2 = 7mATicks Per Frame: 50,000,000 to 833,33350 MHz/Ticks per frame (1-60 frames/sec). Number of 50Mhz clock cycles perframe. Therefore, frame time equals Ticks Per Frame * 20(ns).
