6030 Drum DRUM: Drum hall velocity does not match encoder velocity to within tolerance. All Only applies when running in encoder mode. The maximum discrepancy between speed measured from the Hall sensors and that measured from the encoder ticks, is set by maxdiff If the firmware thinks that there is a speed discrepancy, then either there is no signal from the encoder or no signal from the Hall effect sensors, or, either of these signals is besett with noise that is causing the firmare to think the speed is higher than it is. Check Hall led sequence on drum amp. Check/replace Drum amp J2 to back plane cable, Check tach B signal on MPE test pin with a scope for noise, or irregular pulse width, see 73-0106A, Connect Drum amp break out box 10-3732B between the back plane and drum amp ribbon cable, check for tach signal. Resume. Drum hall velocity does not match encoder velocity to within tolerance. ../error_messages/06026.xmlE_DRUM_TPU_TIMEOUT ../nvs/drum_cfg_maxdiff.xmlNVS: drum maxdiff ..\..\ShowAllErrors.htmFirmware 0 Error Index ..\..\ShowAllCommands.htmFirmware 0 Command Index ..\..\ShowAllNVS.htmFirmware 0 NVS Index Updated: Wed Jul 16 19:32:26 2008 PST http://techplanet.creo.com/output/computer_to_plate/vlf_trendsetter/content/troubleshooting/6030.htmOther: Troubleshooting information
