Bus Over Voltage - Self Resetting
The BUS voltage has exceeded
the upper threshold limit
Bus Under Voltage - Self Resetting
S200 DC drive fault only
BUS voltage is below specified
20 VDC minimum
Motor I-I or I-n Short
Line-to-Line, Line-to-Neutral, or
Line-to-PE short on the motor
ouput causing an instataneous
over current
Output Over Current
Hall Fault
Valid only when drive is set to 6
Step (Hall feedback) operation
SFD Configuration Error
J3 FB +5V Short
Excessive current drain on SFD
+5 supply output
SFD Motor Data Error
Motor data in SFD is outside
drive limits or is inconsistent
AC Line voltage (AC unit) or DC bus power supply
voltage (DC unit) is too high.
Regenative energy during deceleration is cusing the
BUS to rise:
On AC Drives add regen resistor.
On S200 DC input drives external BUS capacitor is too
small; add capacitance.
On S200 DC input drives:
BUS voltage is too low.
BUS voltage is pulled down during high acceleration or
loading.
External BUS capacitor is too small.
Motor power wiring short circuit - line-to-ground/neutral.
Motor cable short line-to-line.
Motor power cable length exceeds the data sheet
specification causing excessive motor line-to-earth
ground/neutral capacitance.
Internal motor winding short circuit.
Motor L too small.
KIP set too large.
Insufficient motor inductance
KIP or KII improperly set causing excessive output
current overshoots.
Invalid configuration.
Motor overspeed.
Invalid hall state.
Invalid hall transition.
SFD UART error during SFD initialization.
Bad motor data check sum.
The drive will attempt to initialize the SFD up to 4 times.
If it fails, this error is reported.
Excessive loading on SFD +5 supply.
Short in the feedback cable on SFD +5 (J3-1) to ground.
Motor and Drive are not compatible. Auto setup calcula-
tion yielded a desired parameter value outside valid range.
Incorrect/inconsistent motor data loaded into the SFD.
