5 Drive Programming User Variables
Drive Programming User’s Manual (I580-E2)
5-2 Input/Output Terminal Variables
5
• The output terminal variables (word access) Yw is a function to use the output terminal variables MX2:
Y(00) to Y(02)/RX: Y(00) to Y(05) as a word-size variable.
• The output terminal variables Y(00) to Y(05) are set in the lower byte. For the upper byte and unused
output terminal variables, zero is read out. If any data is written to the upper byte, the data is ignored.
When the Drive Programming program is stopped, the status before the program stop is
retained for multi-function outputs controlled by the Drive Programming.
For this reason, configure the system so that the stop of the Drive Programming program in the
inverter can be detected by the Drive Programming start signal and the alarm (trip) signal, and
the inverter's peripheral devices can be stopped safely.
• When the Drive Programming program is stopped, the data of the output terminal variables
before the program stop is retained. When the program execution is started again, the pro-
cess begins with the retained data.
However, the outputs with MO1 to MO6 (General-purpose output) not set for the Drive
Programming are controlled as the inverter's multi-function outputs independently of the
program.
• If multiple tasks use the same multi-function terminal, the output status of the task which is
executed last will be effective. Considering safe control, we recommend you to avoid using
multiple tasks for control.
• Even if you select MO1 to MO6 (General-purpose output 1 to 6) for the Multi-function Output
Selection (MX2: P1 and P2/RX: P1 to P5) or for the Multi-function Relay Output (MA, MB)
Function Selection, you can select NO (NO contact) or NC (NC contact) for the Multi-function
Output Operation Selection (MX2: C031 and C032/RX: C031 to C035) or for the Multi-func-
tion Relay Output (MA, MB) Operation Selection (C036).
