MESSAGE
WARNING
CODE
DESCRIPTION RECOMMENDED ACTIONS
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.
– Slave has lost communication with hub
PLC, or slave is masked off in parameter
Master Mask
SpdProfile Limit 101 The sum of the individual ramp times has
exceeded the maximum value for Total
Acceleration Time.
– Set the ramp correctly.
– Contact Factory
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 Speed Cmd Loss.
The warning could be due to the DPI
adapter or the 4-20mA signal wired to the
analog input. Ensure that all connections
are secure, device is powered and operating
correctly.
– Verify the DPI adapter light status and
ensure the device is operating properly
– Verify the customer network is properly
communicated with the device
– Cycle control power to the drive
– Some time the adapter may not get
power prior to drive board, the drive may
detect speed command loss.
– Read DESCRIPTION
Stack Depth 175 Stack size is now greater then the half
allocated at initialization.
– NOT USED
Stnd IO Config 17 XIO Card assigned to Stnd IO is unsable for
this purpose.
– Select the proper slot compatible for
usage.
Stnd IO conflict 18 Stnd IO XIO card has been re-assigned for
another purpose.
– Check configuration of all cards and
reassign if necessary.
SyncXfer Failure 145 A Synchronous Transfer was not completed
in the time specified in Synchronous
Transfer Time (P230). This warning will
occur if the Sync Transfer fault is masked,
and the drive will continue to run at the last
Reference Command before a
synchronization command was initiated.
– Instability at Synchronous Speed - Check
for stability of the synchronous transfer
process/ speed regulator
– Motor can not reach Synchronous Speed
due to heavy load
– Check load conditions for torque limit or
low alpha line (low line voltage)
– Consult factory for review of synchronous
transfer parameters
– This fault indicates that the drive failed to
synchronize the motor to the bypass
within the specified time. Adjust the Sync
Reg Gain (P225), Sync Error Max
(P228), Spd Reg Bandwidth (P81) for a
smooth transfer.
