TM 5-3895-374-24-1 Serial link Detailed Information Command register COM (W18) Read and write on registers W18,0 RST Resetting of speed controller W18,1 DLI Assigning of logic commands in LINE mode W18,2 FLI Assigning of the frequency reference in LINE mode W18,3 - Reserved W18,4 NTO Cancellation of communication control W18,5 RUN Run / stop command W1 8,6 DCB DC injection braking command W18,7 - Reserved W1 8,8 CAL Freewheel stop command W1 8,9 CAR Fast stop command W18,A RTM Motor voltage reduction command W18,B - Reserved W18,C - “ W18,D - “ W18,E - “ W18,F - “ These bits are active at state 1, and have the same function as the bits described previously Bits DLI and FLI provide the possibility of partially assigning the ATV-45 2's commands DLI (W18,1) at state 1 the logic commands (run, stop, brake etc  ) can be carned out In LINE mode At state 0, these are only taken into account on the ATV-45 2 logic inputs FLI (W1 8,2) at state 1 the frequency reference is read In word W19 At state 0, this is taken Into account on the ATV-45 2 analogue input Reading and writing of value 1 in bit B3 (CLI) leads to these two bits being reset to 1, the writing of bit B2 at 1 (CLO) sets them systematically at 0 Note:  these 2 bits must be correctly positioned each time the COM register Is written In an application where the ATV-45 2 Is completely controlled by serial link, they should always be at state 1 State register STR (W20) Read only W20,0 LOC All commands assigned In LOCAL W20,1 RDY Speed controller ready (RDY or SLC) W20,2 FAI Fault present W20,3 REN Resetting authorized W20,4 BCR Brake engage relay closed W20,5 FLO Speed controller overridden In LOCAL control W20,6 NTO Communication control canceled W20,7 CFA Fault present, can be corrected W20,8 RNG Operating (motor rotating) W20,9 RVE Direction (0 = forward, 1 = reverse) W20,A BRE DC injection braking W20,B SST Normal operating mode W20,C OVL Thermal overload alarm W20,D OBR Overbraking alarm W20,E LIM In current limitation W20,F PWD Power voltage failure These bits are significant at state 1 (page 3-270)
