POWERXL DH1 SERIES ADJUSTABLE FREQUENCY DRIVES MN040041EN—August 2019 www.eaton.com
Code Modbus ID Parameter Application RO/RW
P3.1.13 2464 Virtual RO2 Function 1,2,3 RW
Use this parameter to select the function of output relay VO2. This relay is a internal relay that can be used
to tie to internal functions in the drive. The functions are the same with the standard hardware relays.
Setting Value Signal Content
0 = not used - Out of operation
1 = ready - Frequency converter is ready for operation
2 = run F - frequency converter is operating (motor is running
3 = fault - A fault trip has occurred
4 = fault invert - A fault trip not occurred
5 = warning - Always if a warning exists
6 = reverse - The reverse command has been selected
7 = at speed - The output frequency has reached the set reference
8 = zero frequency - Motor output is at zero frequency
9 = frequency limit1 supervision - Supervision for frequency limit1 is activated
10 = frequency limit2 supervision -Supervision for frequency limit2 is activated
11 = pid1 supervision - Supervision for pid1 controller is activated
12 = pid2 supervision - Supervision for pid2 controller is activated
13 = over heat warning - Drive over heat has occurred
14 = over current regular - Over current regulator is enabled
15 = over volt regular - Over volt regulator is enabled
16 = under volt regular - Under volt regulator is enabled
17 = 4 mA fault - 4 mA fault has occurred
20 = torque limit supervision - Supervision for torque limit
21 = reference limit supervision - Supervision for reference limit
22 = control from IO - I/O is the control place
23 = unrequired rotation direction - The active direction isn’t the same with the reference direction
24 = thermal fault - Thermal fault has occurred
25 = fire mode - Drive is in fire mode
26 = bypass running - Drive is in bypass mode
27 = external fault - External fault has occurred
28 = remote control - Remote is the control place
29 = jog speed - Drive is in jog mode
30 = motor thermal protection - Motor is thermal protected
31 = fieldbus input1 - Controlled by FB control word, look at com manuals.
32 = fieldbus input2 - Controlled by FB control word, look at com manuals.
33 = fieldbus input3 - Controlled by FB control word, look at com manuals.
34 = fieldbus intpu4 - Controlled by FB control word, look at com manuals.
35 = damper control - Drive is in damper control
36 = timer1 status - The status of timer1
37 = timer2 status - The status of timer2
38 = timer3 status - The status of timer3
40 = power limit supervision - Supervision for power limit
41 = temperature limit supervision - Supervision for temperature limit
42 = analog input supervision - Supervision for analog input
43 = motor1 control - Motor1 is controlled
48 = logic fulfilled - The status of logic function
49 = pid1 sleep - PID1 controller is in sleep mode
50 = pid2 sleep - PID2 controller is in sleep mode
51 = Motor Current 1 Supv - Motor current supervision value active
52 = Motor Current 2 Supv - Motor current supervision value active
53 = Second AI Limit Supv - Analog input supervision active
54 = DC Charge Switch Close - DC bus is charged (230VAC - 230VDC, 480VAC - 380VDC,
575VAC - 520VDC) fault signal is not effective by this output.
55 = Preheat Active - Preheat Control mode is activated
56 = Cold Weather Active - Cold Weather mode is activated
58 = 2th Stage Ramp Frequency Active - 2nd stage ramp frequency limit reached
59 = STO Fault Output - STO fault is active
60 = Run Bypass/Drive - Run indication for drive and bypass.
61 = Bypass Overload - Bypass Overload fault input is enabled.
62 = Bypass Run - Drive run command for bypass is given
P3.2.1 154 Freq Limit 1 Supv 1,2,3 RW
Use this parameter to select how the frequency converter supervision controller functions as either a high or
low limit based off the set supervision value. It can also be used to enabled an external brake control relay.
0 = No supervision
1 = Low limit supervision
2 = High limit supervision
3 = Brake-on control
