Warning Messages Chapter 2
No Tach Installd 150 The drive has sensed that there is no tachometer/encoder
connected, but the Speed Feedback Mode (P89) has been set to
Pulse Tach. Verify tach requirement for system and change the
tach configuration parameter Tach Type (P233).
• Verify whether there is a tachometer required for the system, and
set the parameter Speed Feedback Mode accordingly.
• Investigate the tachometer for damage.
• Verify the wiring from the drive to the tachometer is per the
electrical drawing.
• Verify the +15VDC supplying the tachometer is not low/missing.
NVRAM Cleared 96 The drive parameters are corrupt and have been initialized to
default values. This happened either during a firmware
upgrade or if the battery was low. Reload the parameters into
the drive
• Reload the parameters from terminal memory, DriveTools,
Flashcard, or from a hardcopy.
Output CtctrOpen 186 The output contactor is open even though it has been
commanded to close.
• Verify the contactor feedback and the 120V wiring to the ACB.
• The drive may be in auto-restart mode following loss of medium
voltage.
• Be sure the associated starter unit is set to Normal mode.
• Verify the feedback from the contactor status (normally control
relay auxiliary and contactor mechanical auxiliary) is wired
properly and powered.
• Verify that there is control power to the contactor.
• Verify the associated ACB I/O.
• Verify that the holding coil or closing coil is not shorted.
• Review the contactor control wiring.
• These warnings may also occur during the auto restart feature, as
the loss of power may also result in the inability to hold in the
contactor during the outage.
Output CtctrClsd 187 The output contactor is closed even though it has been
commanded to open. Verify normal mode of starter the
contactor feedback and the 120V wiring to the ACB.
Output IsoSwClsd 194 The input isolation switch is closed when it is expected to be
open. The switch should be open in System, Gate and Open
Circuit test.
• In DC Current test modes, the isolation switches are expected to be
closed for DC Current test; although only the input contactor is
required the test will run with warnings if the switches are open.
• Be sure the isolation switches are in the proper position for the
specific operating mode (Refer to the description of parameter 141 –
Hardware Option1 in the parameters manual).
• Verify the feedback wiring.
• Verify isolation switch mechanical auxiliary setup.
Output IsoSwOpen 191 The output isolation switch is open when it is expected to be
closed. The switch should be closed in Normal, DC Current test
and Open Loop modes.
Parameter Range 97 The parameter value loaded from the NVRAM or the DIM is
outside the valid range and has been set to default value. The
offending parameter number has been stored in Parameter
Error (P597). Enter the correct value.
• If this was a result of an INIT operation, contact the factory.
• If this was a result of a LOAD operation, correct the parameter value
and perform a SAVE operation.
• Check the settings on the DIM to determine whether it is limiting
the parameter’s max or min values.
