Hellovalparaiso, I presume that you have activated macro 43 i.e. pump control. DI 0 = ON/OFF2 [i.e. p29650 = 0 & p29652 = 722.0 OFF2 via DI 0, p0844 = 29659.1 ON/OFF2 status to BI] i.e. when line contactor is ON, DI 0 = 1 & when line contactor is switched OFF DI 0 = 0. OFF2 - motor coast down at its own i.e. drive pulse are disable/inhabit. If my above assumptions are true, please set below parameters. 1. Set p1254 & p1294 = 0 (i.e. automatic detection of Vdc switch on level) so switch in r1242, r1282 threshold of Vdc max controller are then directly determined by p0210. Please check. |

Hi Parameter P0852, this will inhibit operation if the high signal is lost; the high signal comes from DIN0 the 'run' command. r0054 is a read parameter within the VSD, looking at digital input 0, the run command. As this run command is lost the VSD will shut down, the IGBT output will stop, the VSD will 'coast' the motor to stop. Ensure the DI0, 'the run command' is lost just before the power is chopped. Try setting this parameter and see how the drive shuts down the output, and the motor coasts to a stop. Set P0852 = 54.0 Tractor AttachmentCoast to stop.docx (360 Downloads) |
