Chapter 6 Command Reference - 115 -
Error
Description
E25—Excessive Command
Voltage at Enable
The command voltage (at the ANI+ terminal) was
too high when the drive was enabled. Lower the
voltage at the ANI+ terminal. Try using the fault on
startup voltage. (
FLTSTP
)
E26—Drive Faulted
The drive is faulted.
E27—Bridge Hardware Fault
Excessive current or short on the H-bridge.
E29—Drive Over-voltage
The bus voltage is too high (>410 VDC). Lower
the AC Mains voltage and check for excessive
regeneration power. (
TVBUS
)
E3Ø—Drive Under-voltage
The bus voltage is too low (<85 VDC) or there is
overly aggressive acceleration or deceleration.
Raise the AC Mains voltage. (
TVBUS
)
E31—Bridge Foldback
Drive current was limited to prevent overheating
(warning only). See
DIFOLD
.
E32—Power Regeneration Fault
Check the Regeneration resistor for a short.
E34—Drive Temperature Fault
Wait for the drive to cool down. (
TOTEMP
)
E35—Motor Thermal Model
Fault
The motor thermal model has determined the
motor is too hot. Wait for the motor to cool, and
then re-enable the drive. (
TMTEMP
)
E36—Motor Temperature Fault
Motor thermal switch has tripped. Wait for the
motor to cool, and then re-enable the drive.
(
TMTEMP
)
E37—Bad Hall State
A problem with the Hall sensors exists. Check the
Hall state wiring. (
THALL
)
E38-Feedback Failure
Feedback not present or the signal level is
incorrect. (
TPE, THALL
)
E39—Drive Disabled
The drive is disabled. (
DRIVE
)
E4Ø—PWM Not Active
The H-bridge is not switching.
E41—Power Regeneration
Warning
The drive regenerated (warning only).
E42-Shaft Power Limited
Warning
Shaft power is limited to the rated output to protect
the drive (warning only).
E43-Excessive Speed at
Enable
The motor was turning too fast when the drive was
enabled.
E44-Excessive Position Error
Commanded position. Actual Position is greater
than the value set by
SMPER
.
E45-Excessive Velocity Error
Commanded velocity. Actual Velocity is greater
than the value set by
SMVER
.
E46-Hardware Enable
0 = Hardware Enable (Drive I/O Pin 1 and 21)
1 = No Hardware Enable
E47-Low Voltage Enable
No motor power was present when the drive was
enabled.
E48-Control Power Active
The drive is in Control power mode. No motor
power is present.
E49-Alignment Error
The
ALIGN
command did not complete
successfully. (
TPE, THALL
)
E50-Flash Error
A problem writing to non-volatile memory exists.
(
RFS
).
E51-Resolver Error
A problem determining the correct resolver angle
exists. Applies to Arxx-xR models only. Check the
resolver feedback wiring.
