Error Codes
Table 31 below contains a list of error messages and a brief description of
corrective action.
Error Resolution
E0 Motor Configuration
Warning
The motor rating is too high for the drive/controller, and the
drive/controller is using its own limits for safety reasons.
E1 Motor Configuration Error
One of the motor parameters is set to zero (0). Look at the additional
errors to find which parameters are set at zero (0). Refer to your motor
specifications for the correct value.
E3 Max Inductance = 0
This parameter is set to zero (0). To correct the error, you must set a
non-zero value. Refer to your motor specifications for the correct
value. (C4 Motor Inductance)
E4 Rated Speed = 0
This parameter is set to zero (0). To correct the error, you must set a
non-zero value. Refer to your motor specifications for the correct
value. (C8 Motor Rated Speed)
E5 C9 = 0
This parameter is set to zero (0). To correct the error, you must set a
non-zero value. Refer to your motor specifications for the correct
value. (C9 Number of Motor Pole Pairs)
E6 Resistance = 0
This parameter is set to zero (0). To correct the error, you must set a
non-zero value. Refer to your motor specifications for the correct
value. (C7 Motor Winding Resistance)
E7 Ke = 0
This parameter is set to zero (0). To correct the error, you must set a
non-zero value. Refer to your motor specifications for the correct
value. (C15 Motor Ke)
E8 Continuous Current = 0
This parameter is set to zero (0). To correct the error, you must set a
non-zero value. Refer to your motor specifications for the correct
value. (C1 Continuous Current)
E9 Peak Current = 0
This parameter is set to zero (0). To correct the error, you must set a
non-zero value. Refer to your motor specifications for the correct
value. (C3 Peak Current)
E10 Used Drive Continuous
Current
The continuous current of the motor is higher than the continuous
current rating of the drive/controller. Use the continuous current rating
for the drive/controller.
E11 Torque Rating > Peak Power
Rating
The motor’s torque rating is too high for the power level of the
drive/controller. Use the drive/controller’s torque rating.
E12 Used Drive Peak Current
The peak current of the motor is higher than the peak current rating of
the drive/controller. Use the drive/controller’s value for peak current.
E13 Inertia = 0
This parameter is set to zero (0). The drive/controller will not enable
Velocity or Position Modes. To correct the error, you must set to a
non-zero value. Refer to your motor specifications for the correct
value. (C11 Motor Rotor Inertia / Forcer Mass)
E14 Damping = 0
This parameter is set to zero (0). The drive/controller will not enable
Velocity or Position Modes. To correct the error, you must set to a
non-zero value. Refer to your motor specifications for the correct
value. (C10 Motor Damping)
E26 Drive Faulted
The drive/controller 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 AC Mains voltage
(Motor Input Power) and check for excessive regeneration power.
(S22 Transfer Bus Voltage)
E30 Drive Under-Voltage
The bus voltage is too low (<85 VDC) or there is overly aggressive
acceleration or deceleration. Raise AC Mains voltage (Motor Input
Power). (S22 Transfer Bus Voltage)
E31 Bridge Foldback
Drive/controller current was limited to prevent overheating (warning
only).
E32 Power Regeneration Fault
Check the Regeneration resistor for a short.
