If the program occupancy rate is high (system service occupancy rate is low) as shown below, the system
service may not be performed normally. In the basic parameter, a user can set the value ranging from 50 to 95%,
and if the set value is exceeded, the task program occupancy rate warning is generated. If the program
occupancy rate exceeds 100%, the system enters the ERROR state.
※ Adjust the main task cycle so that the program occupancy rate does not exceed 90%, if possible.
