Error Resolution
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.
E52-Encoder Loss Fault The drive determined there was loss of feedback.
Check the feedback wiring. (TPE, THALL)

Smart Encoders
Several drive related parameters may need additional configuration: CMDDIR,
DCMDZ, and ADDR.
If the Aries drive does not initialize correctly when connected to a Smart
Encoder (Parker motors only) , check the following:
1. Verify the motor phases are wired correctly. Incorrectly wired motor
phases can produce any combination of the following symptoms in the
motor: runs backwards; produces low torque, or gets warm.
2. Check that the feedback cables are wired correctly.
3. Apply power to the Aries drive.
a. Send the SFB command. It should report 5. If the response is not
<*>5, then check the feedback cable (if using a non-Parker cable,
check that it is correctly wired). If the cable is correctly wired and
connected, the problem might be the encoder.
b. Send the THALL command. It should report a number in the range
of 1-6, which indicates the phase wires are connected correctly. If
the response is Ø or 7, a fault exists. Check the motor phase wiring
