Parker Hannifin 130 Aries User Guide
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.
E28-Bridge Temperature Fault Excessive current being commanded:
1. If the application is operating in the peak range,
limiting the peak current setting with DMTLIM can
limit the current commanded and lower the bridge
temperature. Default DMTLIM is 3 x continuous
current, perhaps lowering it to 2.5 x continuous
current or 2 x continuous current can help. This,
however, will limit the motor’s available torque,
which may increase position error and possibly
cause a position error fault.
2. Issue a DIFOLD 1 command. This command
enables the “current foldback” feature in the drive.
However, a drive in “foldback” mode can limit the
motor’s available torque, which may increase
position error and possibly cause a position error
fault.
3. Use a larger Aries amplifier, which would be
capable of higher current outputs.
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. (TDTEMP)
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.
