VFD MON Documentation
This is Varible Frequency Drive which is used for the monitoring the RPM and Ampere of the motor.
Block Icon
VFD MON has three parts first in motor and others two are DACA.
Motor :
When we click on the motor then motor faceplate open where we can see the details related to the motor.
The motor block icon provides a visual representation of the motor’s state using color-coded indicators. Each color or blinking combination signifies a specificoperating condition, helping operators quickly identify the motor's current status.

- 3 Moving Ring : Displays the direction of the motor(reverse or forward).
i. Red : Motor is ready to run.
ii. Green : Motor is running.
iii. Blinking Magenta and Red : Motor is Tripped.
iv. Blinking Yellow and Red : Permission not satisfied in Motor .
v. Blinking Blue and Red : Interlock occured in Motor .
vi. Green with yellow circle : Motor running with permission bypassed .
vii. Green with yellow Blue : Motor running with interlock bypassed .

bypass
the permission for anticlockwise direction. - Interlock – click on checkbox to
bypass
the interlock.
RPM:
It shows the current RPM of motor. When we click on this it open a DACA faceplate.
AMP:
It shows the ampere of the motor. When we click on this it open a DACA faceplate.
The DACA block icon is dynamic, meaning the color of the icon changes when different alarms are activated:
- Low/High Alarm Activation:
- Upon activation of the low or high alarm, the display color will change.
