FWD/REV/STOP has to be used with SR210 or SR213. 2. The operand S 1 should be within the range between 0 and 255. If the station address is 0, it indicates that the PLC broadcasts to all AC motor drives. 3. Please refer to AC Motor Drives User Manual for more information about the setting of S 2 . There is no S 2 in the instruction STOP. 4. FWD: Clockwise running mode n =0: General clockwise running mode n =1: Jog clockwise running mode FWD does not support n if n is neither 0 nor 1. REV: Counterclockwise running mode n =0:
General counterclockwise running mode n =1: Jog counterclockwise running mode REV does not support n if n is neither 0 nor 1. STOP: None 5. If the clockwise running mode is the jog clockwise running mode, S 2 is ineffective. Users can refer to AC Motor Drives User Manual for more information about the modification of the jog frequency. Example: 1. The PLC is connected to the VFD series AC motor drive.
