  3. Control wiring: Connect control terminals for external signals and communication.
  4. Grounding: Ensure proper grounding for safety and noise reduction.

WARNING! High voltage present; disconnect power before installation. Ensure proper grounding.

First-Time Setup

Power on drive; initialize parameters.

  1. Motor parameters: Set motor rated current, voltage, and frequency.
  2. Operation mode: Select V/F control or sensorless vector control.
  3. Acceleration/deceleration: Set appropriate ramp times for application.
  4. Protection settings: Configure overload protection and fault detection.

CAUTION! Verify motor parameters before operation to prevent damage.

Specifications

Controls and Settings

Access parameters via digital operator. Front Panel: RUN/STOP keys, programming keys, LED display.

Digital Operator: RUN, STOP, PROGRAM, UP/DOWN arrows, ENTER, ESC.

Troubleshooting

SymptomPossible CauseCorrective Action
Drive does not startPower/control circuitCheck power supply; verify control signal wiring; check RUN command.
Overcurrent faultMotor/load issuesCheck motor insulation; reduce acceleration time; check for mechanical binding.
Overvoltage faultRegeneration/brakingIncrease deceleration time; install braking resistor if needed.
Motor overheatingOverload/parametersCheck motor load; verify motor parameters; adjust thermal protection.
Communication errorCable/settingsCheck cable connections; verify baud rate and station number settings.

Reset: Clear faults via digital operator or power cycle.
