Chapter 2 Warning Messages
Rec OvrVoltage 157 The rectifier input voltage given by Rec Input Volt (P696) has
exceeded the trip settings.
A warning is logged first and if the overvoltage persists for the
specified time delay a fault is logged.
• This is detected by the hardware circuit in the ACB.
• Verify the parameters and inspect the VSB for possible damage.
• Investigate occurrences of bus transients.
Rectifier 5Pulse 230 The motor current exceeded the maximum allowable level with
seven pulse rectifier gating for the variable torque drive.
Rectifier is operating now in five pulse pattern.
• Check the drive load conditions.
X X X X X X Refrnce Cmd Loss 55 The drive has lost communication with the device responsible
for providing the speed command to the drive. This could either
be a DPI adapter or the 4…20 mA signal or the remote
0…10V.
• Check the DPI adapter status and verify the connections.
• Verify the communication to device providing speed reference.
• Verify the signal wiring on the 4…20mA / 10VDC signal and that it
is properly shielded.
• Check the ACB and replace it if necessary.
X X X X X X RefSlct Conflict 452 An attempt was made to set the torque reference select and the
speed reference select to the same source.
• Verify the wiring to the XIO card.
X X X X X X Regulator Limit 60 The regulators in the drive (Current, Flux and Speed) are
running in the limit.
• The autotune results may not be accurate. Verify the input line
voltage and the load conditions.
• Raise the torque limits if necessary and repeat tuning.
X X X X X X Rs Tune Skipped 372 Rs tuning is skipped because the drive is declared of having an
output isolation transformer (bit 3 of P141 is set).
• Check that the Motor Current HECS (U&W) polarity is correct.
X X X X X X Restart Xpired 369 This warning is issued when both of these conditions exist:
1. The drive is in auto-restart mode (drive is running and then
a loss of medium voltage)
2. the auto-restart timer expired (the medium voltage outage
is longer than specified auto-restart delay time)
• Review of the application to see if the auto restart timer can be
increased. This is just a warning message to indicate the status of
the drive; the auto-restart is no longer active.
X Rotor Not Moved 376 The drive detected that the motor rotor was not moving during
an encoder autotune.
• Check if the rotor is locked or if a heavy load exists.
X X X X X X RStator Low 373 Stator resistance measured during autotuning is negative.
X SavedFanData Clr 350 The saved fan data, which is stored in NVRAM, was cleared. The
saved fan data includes: active fan set and fan run times. Once
the active fan set is cleared the default fan set will be selected
for the next run. The retentive fan data is currently available
only on Heatpipe drives.
X X Slave 0-7 Comm 128…135 Slave (0…7) DAN communication loss-Master only.This
warning is for parallel drives only and indicates on the master
drive that the Slave drive has stopped communication in the
link.
• Slave is offline.
• Check for communication between Master and Slave drives.
