11.2 Diagnostics
The following table lists the S200 fault codes and possible causes of the fault condition.
Status
LED
Blink
Code
Fault Description
Possible Cause
ON
No faults, power
stage Enabled
Normal Operation
OFF
Control power not
applied or insufficient
control power applied
Loose or open circuit wiring of control power input.
Low input voltage to control power supply.
Fast Blink
No faults, power
stage Disabled
Hardware or Software Enable inactive, to enable drive apply
hardware enable and set software enable.
1 Not
Assigned
2 Motor
Over
Temp
Motor temperature
exceeds allowed limit
High ambient temperature at motor.
Insufficient motor heat sinking from motor mounting.
Operating above the motor’s continuous current rating.
Motor temperature sensor failure or not connected.
3 Drive
Over/Under
Temp
Temperature of drive
heatsink/chassis is
outside of allowed
limits
High or low drive ambient temperature.
Restriction of cooling air due to insufficient space around unit..
Operating above the drive’s continuous current rating.
4
Drive I*t Too High
The product of the
drives output current
multiplied by time has
exceeded allowed
limits.
If current foldback is
enabled the drive
peak output current
automatically reduces
to 0.67% of
DIpeak
. If
foldback is not
enabled, the drive will
fault.
Mechanically-jammed motor.
Motion profile acceleration requires peak current for too long of
a time duration.
Machine load on the motor increased by friction.
Wiring problem between drive and motor yielding improper
motion.
Motor commutation error.
Drive under-sized for application, friction or load.
5
Motor I*I*t Too High
Motor current
amplitude squared
multiplied by time has
exceed allowed limits
Mechanically-jammed motor.
Motion profile acceleration requires peak current for too long of
a time duration.
Machine load on the motor increased by friction.
Motor commutation error.
Motor under-sized for application, friction or load.
6
Optional Battery low
Optional fault used to
indicate SFD battery
supply voltage is low
Battery low fault enabled and battery is not installed.
SFD Battery backup voltage is low.
7
Bus Over Voltage -
Self Resetting
The BUS voltage has
exceed the upper
threshold limit
AC Line voltage (AC unit) or DC bus power supply voltage (DC
unit) is too high.
Regenative energy during deceleration is causing the BUS to
rise:
On AC Drives add regen resistor.
On S200 DC input drives external BUS capacitor is too small;
add capacitance.
