Warning Messages Chapter 2
X DCLnk OvrTemp 76 There is a thermal switch in each DC link winding, and they are
connected in series.
The thermal switch in the DC link inductor has detected an over
temperature condition and opened the AC input to the
standard XIO. The alarm is user configurable by parameters in
he Alarm Config group.
• Be sure that the converter cooling fan is working and that the air
flow is not obstructed.
• Check the 120V wiring and the XIO card.
• Make sure there are no distorted waveforms to the DC link. Check if
there are harmonics on line voltages/current.
X DCLnk OvrCurrent 156 The DC link current in Idc Feedback (P322) has exceeded the DC
link current trip settings. A warning is logged first and if the
over-current persists for the time delay a fault is logged.
• See associated fault description.
• Verify the parameter settings of the drive.
• Check the HECS and burden resistor.
• Confirm stable operation of the drive and any sudden load
transients.
X DCSL Conflict 507 Synchronous transfer or parallel follower drives features cannot
be enabled if DCSL feature is already enabled.
• Check DCSL Config (P955), bit 0, Enable.
X DCSL Not Enabled 506 DCSL feature is not enabled. This feature is mutually exclusive
with either synchronous transfer or parallel drives.
• Check Special Features (P99), bit 5, SyncXfr Enab, and Powerup
Config (P717).
X X X X DecLined Master 122 This warning is for parallel drives only and indicates that the
slave drive was requested to be the Master, but it was unable to
comply.
• Slave has lost communication with hub PLC, or slave is masked off
in parameter Master Mask.
X Desync Delay 146 A transfer from the line back to drive (desync) has been
commanded, but it has been less than 1 minute since the
transfer from drive to line (sync) was completed. As a result, the
output motor filter capacitors have not had time to adequately
discharge.
• Wait for 1 minute and attempt the desync transfer again.
• Insufficient time gap between drive sync and attempted desync.
Wait till the motor filter capacitor has discharged and the drive is in
READY mode.
X Drive OvrLoad 152 The drive has detected an overload condition in the drive
indicated by Drive Overload (P551). A Drive Overload warning
has been detected, where the overload condition is calculated
using DC Current Feedback (P322) and Drive Overload Warning
(P270) as the point where the overload warning occurs. (P270)
is programmed as a percentage of the difference between Line
Overload Minimum (P269) and Line Overload Trip (P163).
• Transient loading – Check the torque limit and overload settings
and compare loading to torque settings and trip settings.
• Verify the drive sizing and that the overload parameters to meet
the load requirements. Verify HECS feedback and burden resistors.
X Drv Maintenance 212 Drive maintenance is due. Contact the factory. Not Used
X Drv in Test Mode 59 The drive operating mode (P4) is programmed in test mode
(Gate, System, DC Current, Open Circuit or Open Loop) when
initiated for autotune test. Place drive back in Normal mode
before autotune.
• Place drive back in Normal mode before attempting autotune.
X DuplctMaster Wrn 500 A Master drive detected another Master on DCSL and has
reverted to the role of Follower.
• Check DCSL Config (P955), bit 1, Master.
