Warning Messages Chapter 2
X X Slave RfsdMstr 123 Slave refused Master-master only. This warning is for parallel
drives only and indicates that the Master requested the Slave to
be the Master, but the Slave drive refused.
• The Slave drive has lost communication with hub PLC, or the Slave
drive is masked off in parameter Master Mask (718).
X X Slave1 UnderVolt 154 This warning is valid for 18-pulse drives only. The measured
slave voltage Slave1 Line Volt (P137) is less than the Line
UndVolt Lvl (P167) setting.
• Verify the VSB connections and tap settings, and check the
resistance of the VSB board. Megger the board to confirm integrity.
• Check the TSN fusing.
• Check the actual voltage values on the terminal for each bridge and
the total line voltage.
• Check for possible source voltage supply problems.
• Use a multimeter and oscilloscope to check the voltages on the
drive test points.
• Verify the parameter settings.
• Verify the tap settings. Investigate occurrences of bus transients.
X X Slave2 UnderVolt 155 This warning is valid for 18-pulse drives only. The measured
slave voltage Slave2 Line Volt (#P138) is less than the Line
UndVolt Lvl (P167) setting.
X Spd BW Reduced 518 Speed bandwidth has been reduced to 5 rad/sec as the signal
from the encoder was lost or parallel drives have been selected.
• Be sure that the encoder is powered and functioning correctly and
that parameter Powerup Config (P717) is not set for parallel drives.
X X X SpecApp Config 27 The XIO card which is being assigned is not a card which can be
used for this purpose.
• Select the proper slot containing a compatible XIO card.
X X X SpecApp Conflict 28 The XIO card previously used has been reassigned to another
function.
• Check the configuration of all XIO slots.
X X X X X X Speed Cmd Loss 55 The drive has lost communication with the device responsible
for providing the speed command for the drive. The warning is
configured by parameter Ref Command Loss (749). The
warning could be due to the DPI adapter or the 4…20mA
signal wired to the analog input.
• Verify the DPI adapter LED status and be sure the device is
operating properly.
• Verify that the customer network is properly communicating with
the device.
• Cycle control power to the drive.
• Sometimes the adapter may not get power prior to the drive board,
and the drive may detect speed command loss.
X X X X X X SpdProfile Limit 101 The sum of the individual ramp times has exceeded the
maximum value for total acceleration time.
• Set the ramp correctly.
• Contact the factory.
Stack Depth 175 The stack size is now greater then the half allocated at
initialization.
Not Used
X X X X X X Stnd IO Config 17 The XIO card assigned to XIO Standard Input/Output is unstable
for this purpose.
• Select the proper slot compatible for usage.
X X X X X X Stnd IO conflict 18 An XIO Standard Input/Output XIO card has been re-assigned
for another purpose.
• Check the configuration of all cards and reassign if necessary.
