Common Fault Codes

OI.AC: Instantaneous overcurrent on the AC output. The drive output current has exceeded the instantaneous trip threshold.
Check for short circuit or ground fault on motor cables. Verify motor insulation resistance. Reduce acceleration rate or check for mechanical overload on the motor shaft.
OV: DC bus overvoltage. The DC link voltage has exceeded the maximum permissible level, typically caused by regenerative energy during deceleration.
Increase deceleration ramp time. Check supply voltage for transients. Install or verify operation of dynamic braking resistor and braking transistor.
UV: DC bus undervoltage. The DC link voltage has fallen below the minimum threshold, indicating a supply voltage dip or loss.
Check incoming supply voltage and connections. Verify supply fuses and contactors. If supply is stable, check internal DC bus capacitors for degradation.
OHt.drv: Drive overtemperature. The heatsink temperature has exceeded the permissible limit.
Check that cooling fans are operational and unobstructed. Verify ambient temperature is within specification. Check for blocked ventilation slots. Consider derating the drive if ambient temperature exceeds 40 deg C.
OHt.motor: Motor overtemperature. The motor thermistor input has detected an overtemperature condition.
Check motor thermistor wiring and continuity. Verify motor is not mechanically overloaded. Allow motor to cool and investigate root cause of thermal overload.
PH: Input phase loss. One or more input supply phases are missing or have an unacceptable voltage imbalance.
Check all three input supply phases at the drive terminals. Inspect supply fuses, cable connections, and upstream contactors. Verify supply voltage balance between phases.
ENC: Encoder feedback fault. The drive has detected a loss of encoder signal, wiring fault, or encoder supply failure on the feedback interface.
Check encoder cable wiring, shielding, and connector integrity. Verify encoder supply voltage. Inspect encoder for mechanical damage. Check parameter settings for encoder type and resolution match.
th: Drive thermistor or thermal model trip. The internal thermal model or thermistor input indicates the drive is operating beyond its thermal capacity.
Reduce continuous output current demand. Check duty cycle and load profile. Verify cooling airflow and ambient conditions. Check thermistor wiring if external thermistor is used.

Frequently Asked Questions

What motor types are compatible with the Unidrive SP?

The Unidrive SP supports standard AC induction motors in open-loop and closed-loop vector modes, as well as permanent magnet servo motors in servo (RFC) mode. Brushless AC servo motors with appropriate feedback devices such as encoders or resolvers are fully supported.

What communication protocols does the Unidrive SP support?

Onboard, the Unidrive SP provides RS485 Modbus RTU communication. Additional fieldbus protocols including PROFIBUS-DP, DeviceNet, CANopen, EtherNet/IP, and others are available via optional plug-in Solutions Modules installed in the drive's expansion slot.

Can the Unidrive SP perform positioning and motion control functions?

Yes, with the optional SM-Applications or SM-Applications Plus module, the Unidrive SP can execute onboard motion control programs including positioning, electronic gearing, and cam profiling. This allows the drive to function as a single-axis motion controller without requiring an external PLC.

Is Safe Torque Off (STO) available on the Unidrive SP?

Safe Torque Off functionality is available on the Unidrive SP through the optional SM-Safety Solutions Module. This provides a safety-rated method of disabling drive output torque without removing main power, suitable for safety category requirements per IEC 62061 and EN 13849.

What is the purpose of the Solutions Module slots on the Unidrive SP?

The Unidrive SP features up to three Solutions Module slots that accept plug-in option cards for expanding functionality. These modules can add fieldbus communication, additional I/O, encoder feedback interfaces, application programming capability, or functional safety features, allowing the drive to be configured for specific application requirements.

Troubleshooting

Drive displays OI.AC fault immediately on enable or during acceleration

Check output phase cables for short circuits or ground faults using an insulation resistance tester. Inspect motor winding resistance for balance between phases. Review acceleration ramp time settings in drive parameters.

Repair or replace damaged motor cables. If motor insulation is degraded, service or replace the motor. Increase the acceleration ramp time parameter to reduce inrush current demand. If fault persists with no load, the drive output stage IGBTs may require inspection or replacement.

Drive powers up but display is blank or shows no response

Measure the 24V DC control supply at the drive control terminals. Check the internal control power supply by measuring voltages on the control board. Inspect for blown internal fuses on the control board.

Verify that the correct supply voltage is applied to the drive power terminals. Replace any blown internal fuses. If the control board power supply has failed, the control board or power supply section will require repair or replacement by a qualified technician.

Motor runs but speed is unstable or oscillates in closed-loop mode

Check encoder wiring for loose connections, poor shielding, or interference from power cables running in parallel. Verify encoder resolution parameter matches the actual encoder specification. Review speed loop gain parameters (proportional and integral gains).

Re-route encoder cable away from power cables and ensure the shield is grounded at one end only. Correct the encoder lines-per-revolution parameter in the drive. Reduce speed loop proportional gain incrementally until oscillation ceases, then optimize integral gain for desired response.

Drive trips on OV fault during deceleration

Monitor DC bus voltage during deceleration using the drive's diagnostic parameters. Determine whether a dynamic braking resistor is installed and whether the braking transistor is active during the fault condition.

Increase the deceleration ramp time to reduce regenerative energy returned to the DC bus. If a braking resistor is installed, verify its resistance value and power rating are correct for the application and that wiring connections are secure. If no braking resistor is present, install an appropriately rated resistor and enable the braking function in the drive parameters.

Fieldbus communication loss between drive and PLC or controller

Verify the Solutions Module is correctly seated in the drive slot and that the module type matches the configured fieldbus. Check network cable connections, termination resistors, and node address settings. Review drive and PLC diagnostic registers for communication status.

Reseat the Solutions Module firmly in the expansion slot. Confirm correct node address and baud rate are set in the drive parameters to match the network configuration. Ensure network termination resistors are installed at both ends of the fieldbus segment. Replace the Solutions Module if hardware fault is confirmed.
