Rockwell Automation Publication 7000-TG002J-EN-P - March 2015 67
Warning Messages Chapter 2
Invalid DIM 99 The drive tried to access the DIM, but either encountered a
problem with the checksum on the DIM, or the DIM was not
installed.
• This fault may occur on drives upgrading major revisions of
firmware with the older DIM installed, or if the DIM has a failure.
• Remove the DIM.
Invalid Mstr Req 124 Invalid Master request-slave only
This warning is for parallel drives only and indicates that the
slave drive refused to the request to be the Master because it
detected that another Master is active on the link.
• Drive tried to become master when another master was already
active.
InvOvrVoltage SW 368 The drive has detected an over-voltage at the inverter output
terminals in software for long cable applications. A fault is
issued if the drive is gating else a warning is issued.
• Verify that the Motor Overvoltage Trip (P181) is set correctly.
• Verify that the motor cables are not disconnected.
• Verify that the load is not overhauling the motor (this warning is
generated while the drive is not gating).
• Contact Medium Voltage Tech Support for assistance.
IsoTx Fan1 Ctctr 202 Isolation transformer fan 1 contactor
This warning indicates that while the drive was running it
detected the loss of the main cooling fan in the isolation
transformer cabinet.
• Isolation transformer fan status is not high while the drive asked
the contactor to be closed.
• This warning occurs when the drive commands the isolation
transformer fan contactor to close, and does not detect the status
feedback from the contactor.
• Verify the fan contactor, fan overload and the 120V wiring to the
standard XIO card.
IsoTx Fan2 Ctctr 203 Isolation transformer fan 2 contactor
This warning indicates that while the drive was running it
detected the loss of the redundant cooling fan in the isolation
transformer cabinet.
IsoTx Fan1 Loss 210 Isolation transformer fan 1 loss
This warning is for drives with redundant isolation transformer
fan option. The drive detected the loss of fan 1 and starts fan 2.
Investigate the fan 1 loss and verify fan 2 operation.
• This warning occurs when the drive detects a loss of pressure or a
loss of Fan contactor feedback when running.
• This warning occurs when the drive detects a loss of pressure or a
loss of fan 2 contactor feedback when running.
• Reset warning at next shutdown and fan 1 will start running.
IsoTx Fan2 Loss 211 Isolation transformer fan 2 Loss
This warning is for drives with redundant isolation transformer
fan option. The drive detected the loss of fan 2 and starts fan 1.
Investigate the fan 2 loss and verify fan 1 operation.
XIsoTx AirFlow
(A-Frame Only)
205 The pressure sensed by the pressure transducer in the integral
isolation transformer section (as a voltage) has dropped below
the value set in pressure value transformer warning (P653).
• Verify fan rotation.
• Check for blockage in the filters / ducting (if installed) and clean as
required.
• Check for improper warning settings. Verify the pressure value
voltage level when running with clear air flow.
• Verify the alarm and trip set-up procedure was completed
adequately and adjust as necessary.
• For drives with external ducting, verify that there is sufficient air to
the drive input.
• Verify the supply voltage to the pressure transducer and confirm
that the output is stable.
• Be sure that the pressure sensor is working and is connected to the
ACB.
