13. Appendix H: Alarms
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).
Error Code HPD: 1
Error Code HPD: 2
Error Code HPD: 3
Error Code HPD: 4
Error Code HPD: 5
Error Code HPD: 6
On start up, the display
doesn’t read IDLE or
RUN or it stays off
Over Voltage on the D.C. Link. Check the three-phase power
line (max 460 V).
Check the break circuit and the braking resistor
Under Voltage on the D.C. Link. Check the three-phase power
line (minimum voltage: 90 V).
Over current. Check for any mechanical blockage and make
sure the motor is the appropriate size for its current use.
Check the motor connections and for any phase-phase or phase-
ground short-circuits.
Check the machine speed and the service cycle.
Make sure a line trap isn’t connected to the motor!
Resolver. Check the connections of the resolver and the
connectors on both sides (drive-motor).
Motor Over Temperature
Check the connection of the PTC motor on terminals 1 and 2 of
X1.
Check the settings of parameters Pr33 (Inom) and Pr19
(Ipicco).
Drive Over Temperature. Check the cooling fans and for any
restrictions to air flow.
Check the breaking cycle.
Check the environmental temperature of the electrical control
panel where the drive is installed, as well as the external
room temperature.
Check the external fuses on the three-phase power supply.
Make sure that the line traps (if installed) and motor are
connected correctly.
Check the voltage on the power supply terminals X4, terminals
1, 2, and 3.
Check the bridge on X4 between terminals 7 and 8.
