Fault Message
Problem or Symptom Potential Cause Possible Resolution
NODE ALARM 01…CTRL UPDATE
Control Connection Update
Alarm
The Control Update Alarm bit is used to
indicate that updates from the
controller have been late
Excessive network traffic.
• Remove unnecessary network
devices from the motion
network.
• Change the network topology
so that fewer devices share
common paths.
• Use faster/higher performance
network equipment.
Noisy environment.
• Segregate signal wiring from
power wiring.
• Use shielded cables.
• Add snubbers to power
devices.
NODE ALARM 05…CLOCK SYNC Clock Jitter Alarm
Sync Variance has exceeded the Sync
Threshold while the device is running in
Sync mode.
• Switched to grandmaster
clock of significantly
different frequency.
• Lost connection to
grandmaster clock.
• Drive auto-corrects upon time
synchronization.
• Restore network connections.
NODE ALARM 128…NODE SWITCH No Quick View message
The node address switches have been
altered because they were first read
after powerup.
Node Switches adjusted
after powerup. Return node switches to power-
up setting.

Fault Message
Problem or Symptom Potential Cause Possible Resolution
ALARM S52…POS SW OTRAVEL
(Kinetix 6200 drives only)
Software Overtravel - Positive
Axis position exceeded maximum software setting.
• Verify motion profile.
• Verify overtravel settings are
appropriate. ALARM S53…NEG SW OTRAVEL
(Kinetix 6200 drives only)
Software Overtravel - Negative
ALARM M13…POWER CYCLE UL
(Kinetix 6200 drives only)
N/A
(1)
The converter estimates that the pre-
charge circuit has exceeded its limit due
to excessive power cycling.
The DC bus power has been
cycled too frequently. Limit power cycles to two per
minute maximum.
