Operands:
S : Address of communication device n: Target to be instructed
Explanations:
1. Range of S : K0 ~ K31
2. Range of n : K1 or K2
3. See the specifications of each model for their range of use.
4. Flags: See API 80 RS for explanations on M1120 ~ M1131, M1140 ~ M1143
5. RSTEF is a handy communication instruction exclusively for Delta VFD-A series AC motor drives and is used
for reset when the AC motor drive operates abnormally.
6. n: instructed target. n=1: AC motor drive at assigned address. n=2: all connected AC motor drives.
7. The feedback (returned) data from the peripheral equipment will be stored in D1070 ~ D1089. If n = 2, there will
be no feedback data.
Remarks:
1. The activation criteria placed before the three instructions, API 100 MODRD, API 105 RDST and API 150
MODRW (Function Code 03), cannot use rising-edge contacts (LDP, ANDP ORP) and falling-edge contacts
(LDF, ANDF, ORF); otherwise, the data stores in the receiving registers will be incorrect.
2. For the registers for flag settings, see explanations in API 80 RS.
3. There is no limitation on the times of using this instruction in the program, but only one instruction is allowed to
be executed at a time.
