Warning
Description
Code
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.
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.
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.
452
An attempt was made to set the torque reference select and the
speed reference select to the same source.
60
The regulators in the drive (Current, Flux and Speed) are
running in the limit.
372
Rs tuning is skipped because the drive is declared of having an
output isolation transformer (bit 3 of P141 is set).
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)
376
The drive detected that the motor rotor was not moving during
an encoder autotune.
373
Stator resistance measured during autotuning is negative.
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.
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.
Recommended Action(s)
• 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.
• Check the drive load conditions.
• 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.
• Verify the wiring to the XIO card.
• 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.
• Check that the Motor Current HECS (U&W) polarity is correct.
• 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.
• Check if the rotor is locked or if a heavy load exists.
• Slave is offline.
• Check for communication between Master and Slave drives.
