Replacing an ETM with the keypad
Easy retrofit or add to any system
ETMs (elapsed time meters) areimportant for VFDs, especially in the W&WW industry. They are used to view equipment
run times, which is beneficial for scheduling maintenance. The traditionalsolution isto install aseparate ETM on the
VFD control panel. While functional, adding a separate ETM to theVFD control panel today adds unnecessary costs
since the 580-drive series has an ETM built into the control panel (keypad). The VFD’s built in ETM is readily available
and non-resettable on the control panel’s “home view” and does not require diving deep into the VFD parameters. The
ETM is flexible and shows hours, days of running, or how long the VFD has been powered. This document is applicable
for ACH580, ACQ580, and ACS580 drives and will show how to setup the ETM on the keypad’s home screen.
Accessing and setting up the ETM on the keypad (control panel) home screen
The ETM functionality is accessed on the control panel by selecting the following:
Options > Edit Home view > Select Screen Location to insert ETM > Edit > Parameter > Other > 05 Diagnostics
> 05.03 Hours run (hours)
Refer to the control panel screen shots below for step-by-step instructions to access the different ETM parameters.
Note: the example below is froman ACQ580 drive, the steps areidentical for the ACH580 and ACS580 drives. This run-
time counter is non-resettable.

12. Navigate to the On-time counterhome screen
Press either the left or right keys to navigate to the On-time counter
home screen. See Figure 12.
The On-time counter displays the number of days the VFD has powered.
Advantages of using the built-in ETM
Adding a separate ETM to a panel adds unnecessary costs to the panel including wiring and a relay (see Figure 13). An
advantage of using the VFD keypad for the ETM, is that the run time information can be communicated through a
SCADAsystem as opposed to using a separate ETM which cannot communicate without providing additional ancillary
equipment. Also, the ETM screen can easily be added on the keypad VFD panel which did not have a separate ETM built
into the panel.
Figure 13
In summary, the 580 drives series keypad can be used to replace a separately mounted ETM on the VFD panel. The

keypad counters can quickly besetup to show three different counters which include the motor run timein days, the
motor run time in hours, and how long the VFD has been powered for in days. This information can be beneficial for
scheduling maintenance. While functional, adding a separate ETM to theVFD control panel adds unnecessary costs
since the 580-drive series has it built into the keypad.
