Cause
Earthed/Grounded Network
The sum of line currents measured with
internal current transducers is too high.
Earth fault in AC filter, line converter, DC link,
inverter(s), motor cables or motor, or current
unbalance in parallel connected converters.
Network voltage is lost during modulation. Line
current is below 0.0064 × I
situation may cause DC link undervoltage.
A Local Control device (CDP 312 or
DriveWindow) has ceased communicating.
This can be caused by the disconnection of the
selected local control device during local
control or an internal fault in the local
controlling device. This warning transfers the
ISU to remote mode.
This message is generated by the Control
Panel CDP 312 control program.
There is a cabling problem or a hardware
malfunction on the Panel Link.
(4) = Panel type is not compatible with the
version of the converter application program.
The ID number of the ISU has been changed
from 1 (the change is not displayed on the
Control Panel CDP 312).
Factory parameter settings are being restored. Please wait.
Cause
The ACS 600 internal temperature is
excessive. The trip level of the converter
module temperature is 125 °C.
I/O control board temperature is lower than
+5 °C or exceeds +73 °C.
DC link voltage is not high enough after
charging procedure.
DC link voltage has not exceeded the value of
Par. 30.12 DC UNDERVOLT TRIP or current is
not below 5% of I
1base (10s/60s)
charging.
Faulty PPCC link (DC voltage measurement is
zero).
What to do
Check motors.
Check motor cables.
Check the ISU fuses (parallel connected
units).
Check the ISU.
Check inverter(s).
Check AC filter.
Check network conditions.
. The
1base (10s/60s)
Check Control Panel connector. Replace
Control Panel in the mounting platform.
Check the Panel Link connections.
Press the RESET key. The panel reset may
take up to half a minute, please wait.
Check the Panel type and the version of the
drive application program. The Panel type is
printed on the cover of the Panel.
To change the ID number back to 1 go to Drive
Selection Mode by pressing DRIVE. Press
ENTER. Set the ID number to 1. Press
ENTER.
What to do
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check line current against unit current.
Check ambient temperature in the auxiliary
control unit (ACU).
Check charging circuit fuses.
Check charging circuit.
Check possible short-circuit in DC link.
Check the setting of Par. 30.12 DC
at the end of the UNDERVOLT TRIP.
Check the PPCC link. See fault message
PPCC LINK.
