Functional Software description20 DCS 500 Software Description- Stop because of problems with the panel link (communicationbetween drive and control panel CDP 312)if the serial link between the drive and the control panel is inter-rupted by any reason (panel removed from the drive, cablebroken, etc) the reaction of the drive can be specified byparamter PANEL_DISC_MODE (918):0 = stop by ramp (DECEL1 (1709) or DECEL2 (1712) )at RAMP GENERATOR function block1 = stop by torque limit (TORQ_MAX / TORQ_MIN)2 = stop by coasting (torque is zero)3 = stop by dynamic brake4 = continue remoteThe drive will come up with a FAULT, which must be reset andwhich will open all contactors at zero speed (with coasting im-mediatelly).- Stop because of problems with the field bus serial link(communication between drive and progr. logic controller)if something is wrong with the field bus serial link (betweenPLC and serial link adapter module or between adapter moduleand drive) the reaction of the drive can be specified by pa-rameter COMFAULT_MODE (920):0 = stop by ramp (DECEL1 (1709) or DECEL2 (1712) )at RAMP GENERATOR function block1 = stop by torque limit (TORQ_MAX / TORQ_MIN)2 = stop by coasting (torque is zero)3 = no actionThe drive will FAULT and must be reset and will open all con-tactors at zero speed (with coasting immediatelly).Reset the drivefaultThe drive can be reset using the input [RESET] (907) or in localcontrol mode by means of the control panel CDP312 by pressingthe RESET-button. The drive recognises the rising edge of the sig-nal. To be able to restart the drive after trip, there has to be a risingedge in signal ON/OFF-input . The technique prevents the RESET-input signal from self-commanding the contactors "ON".
