What are the binary input command functions RUN right and RUN left for the SED2?
The basic functions are the same, but there is a difference. On SED2 setting P0700 = 2, P0701 = 1 and P0702 = 2 allows the user to give the inverter RUN right and RUN left commands. With this setting, however, the user must first allow an already running inverter to stop before applying the RUN command for running in the opposite direction.If for example the inverter was running right and receives a RUN left command before the inverter is stopped, the RUN left command will be ignored. For applications where a change of direction while running is required we would recommend using the REVERSE command. This allows a change of direction without removal of the RUN command and the factory default setting DIN1 – RUN right (P0701 = 1) and DIN2 = REVERSE (P0702 = 12). What must be noted is that the REVERSE command on its own will not cause the inverter to start, so that it should be used in conjunction with DIN1 (RUN). This can cause difficulty if the machine PLC software is already such that a
