Operands:
S: Address of communication device n: Operation mode
Explanations:
1. M1177 = OFF (Default), RSTEF instruction supports COM2(RS-485).
2. M1177= ON, RSTEF instruction supports 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), RSTEF instruction supports 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 RSTEF instruction, however only one instruction 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 before
RSTEF instruction, sending request flags M1122 (COM2) / M1316 (COM3) has to be 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 S
1
: K0 ~ K31
b) n = Communication mode. Range: K1 ~ K2. n = 1: communicate with VFD at designated
address. n = 2: communicate with all connected VFDs. .
c) RSTEF is a handy communication instruction used for reset when errors occur in AC
motor drive operation.
d) The feedback data from the peripheral equipment will be stored in D1070 ~ D1080. When
n = 2, PLC will not receive any data.
8. M1177 = ON, other Delta VFDs are supoported
 S
1
= Address of VFD. Range of S
1
: K0 ~ K255, when S
1
is specified as K0, PLC will
broadcast to all connected VFDs
