Parker Hannifin S.p.A. - Divisione S.B.C.                                                                                LVD User’s Manual

Appendix H : troubleshooting 

 

If problems are encountered with the drive or the control system, use the following table to 
identify the fault and take the recommended corrective action. 

 

To cancel the error on the drive, first remedy the cause and then set Pb99.10 = 1 (reset).

 

 

Fault or error type 

                                     Corrective action 

 

 

Error Code LVD:  1

 

 

 
 

Error Code LVD:  2

 

 

 

Error Code LVD:  3

 

 

 

 

 
 

Error Code LVD:  4

 

 

 

 

Error Code LVD:  6

 

 
 

 

 

 

 

 

When the display 
switches on it fails to 
present the message IDLE 
or RUN, or it remains 
blank 

 
 
 

The LVD drive LED 
display shows decimal 
points in the place of all 
characters.

 

 

Over Voltage

 on D.C. Link.  Check the three-phase 

power line (max 253 V). 

 
 

Under Voltage

 on D.C. Link Check the three-phase 

power line (minimum voltage: 130 V). 

 

Overcurrent

 alarm. Check motor connections and 

possible shorts between phase-phase or phase-ground. 
Check that a mains filter is not connector to the motor! 

 
 
 

Resolver 

alarm. Check the resolver connections and the 

connectors on both sides (drive-motor). 
 

Drive overtemperature 

alarm. Check the cooling fans 

and ensure that the air flow is not obstructed or restricted. 

 

Check the braking cycle. 

 

Check internal temperature of the panel in which the drive 
is installed and external ambient temperature. 

 

Check the external fuses on the three-phase power supply 
line. 

 

Check that mains filters and motor filters (if present) are 
correctly connected. 

 

Check the keypad connection and ensure it is correctly 
installed. 
 
The converter enters I²T limiter function because of an 
overload (current demands are higher than the maximum 
output current). 

 

Check: 

 

- Wiring between LVD motor (no inverted phases). Pay 
special attention in the case of motors with a terminal strip 
rather than a connector, as incorrect connections are more 
easily made. Follow wiring plans scrupulously. 

 

 

 

- Physical sizing 

 

 

The motor overruns when 
the drive is enabled. 

 

The most probable cause is incorrect connect ion between 
the drive encoder output (X4) and the encoder input on the 
axis controller.
