M1177 = OFF (Default), FWD, REV, STOP instructions support COM2(RS-485).2. M1177= ON, FWD, REV, STOP instructions support COM2(RS-485), COM3(RS-485).3. M1177 has to be set up in advance for selecting the target model of VFD. When M1177 = OFF(Default), FWD, REV, STOP instructions support Delta’s VFD-A inverter. When M1177 = ON,these instructions support other models of VFD inverters, e.g. VFD-B, VFD.4. There is no limitation on the times of using FWD, REV, STOP instruction, however only oneinstruction can be executed on single COM port at a time.5. If rising-edge (LDP, ANDP, ORP) or falling-edge (LDF, ANDF, ORF) contacts are used beforeFWD, REV, STOP instructions, sending request flags M1122 (COM2) / M1316 (COM3) has tobe enabled in advance for obtaining correct operation.6. For detailed information of associated flags and special registers, please refer to RS instruction.7. M1177 = OFF, only Delta VFD-A is supported and the definition of each operand is:a) S 1 = Address of VFD-A. Range of S1: K0 ~ K31b) S2 = Operation frequency of VFD. Set value for VFD A-type inverter: K0 ~ K4,000 (0.0Hz~ 400.0Hz).c) n = Communication mode. Range: K1 ~ K2. n = 1: communicate with VFD at designatedaddress. n = 2: communicate with all connected VFDs. .
