17 Information
The driver is equipped with a function to generate information output before an alarm is generated.
This function can be utilized for periodic maintenance of equipment by setting a suitable value in the parameter of each
information.
Status when information is generated
z
Information bit output
If information is generated, a bit output (INFO-
**
output) of the corresponding information is turned ON.
Each bit output of information can be assigned to direct output or remote output. Also, the output state can be
checked with the internal I/O monitor and waveform monitor of the
MEXE02
, or the maintenance command via RS-485
communication.
z
INFO output
If any of information is generated, the INFO output will be turned ON.
z
LED indicator
If information is generated, the PWR/ALM LED will blink twice in orange.
z
Motor operation
The motor continues to operate during information unlike in the case of an alarm.
Related parameters
A generation condition for some information can be adjusted by parameter setting.
Each information has a corresponding "INFO action" parameter. If the parameter is set to "INFO action is not applied,"
only the bit output of information is turned ON, and the INFO output and LED are not changed.
Also, by setting the "INFO auto clear" parameter, you can select whether the INFO output or the bit output of the
corresponding information is automatically turned OFF when the cause of information is cleared.
Clear information
At the factory setting, the generated information will automatically be cleared if the release condition is satised
("Information auto clear" parameter: "Enable").
If the generated state is required to keep, set the "Information auto clear" parameter to "Disable."
Setting to "Disable" will continue the generated state of the information even if the release condition is satised.
17.1 Information history
Up to 16 generated information are saved in the RAM in order of the latest to oldest.
Information items stored as the information history are the information code, generation time, and contents of
information.
The information history stored can be read and cleared when one of the following items is performed.
•
Read and clear the information history using the information monitor of the
MEXE02
.
•
Read the information history by the monitor command via RS-485 communication.
•
Clear the information history by the maintenance command via RS-485 communication.
Note
•
Information history will be cleared if the power supply of the driver is turned OFF because it is saved in the RAM.
•
Clearing the information history cannot be executed in a state where the HMI input is OFF (non-active state).
