Chapter 6 Applied Instructions 3. When M3 is ON (at this time, the value in D206 is ignored), VFD decelerates to stop after receiving the stop command. 4. When M4 is ON, the instruction reads the values of H2100–H2104 of VFD and stores them in D220–224. The state of the VFD: Bit2=1 causes the VFD to execute the Jog command. Bit4–3=11B causes the VFD to run counterclockwise. The in the communication protocol, refer to the Delta AC Motor Drive user manual. frequency command is 18000, and causes the VFD to run at 180Hz. For the definitions of the parameter addresses 5.
The reception completion flag SM100 is ON, and the values of M1–M5 are cleared to avoid interfering with the next communication command. After receiving the data that the VFD sends back, the instruction checks the format of the data sent back from VFD. If the data format is correct, SM100 is ON; otherwise, SM102 is ON. 6_ 6-571 Device D220 D221 D222 D223 D224 Content Error code VFD state Frequency command Output frequency Output current
