Maximum current reached

What does 0x238A mean?

This information message indicates that the actual current (0x6078, P103.00) is equal to or higher than the configured maximum current (0x6073, P324.00). It suggests the motor is operating at its current limit.

• Motor operating with an actual load exceeding its rated continuous torque, leading to sustained high current draw.
• Configured maximum current limit (P324.00) set too low for the application's peak or continuous operational current.
• Mechanical binding or increased friction in the driven system, requiring the motor to deliver higher torque than expected.
• Incorrect motor data or drive parameterization (e.g., P103.00, P300.00) leading to inaccurate current monitoring or limits.
• Intermittent short circuits or insulation breakdown in motor windings or motor cables (terminals U, V, W).

Click steps to track your progress.

1. 1

   Measure the actual current (0x6078 or via external clamp meter on motor cables) during various operating states and compare to motor nameplate data.

2. 2

   Increase the maximum current limit (P324.00) in appropriate increments, ensuring it remains within the motor and drive's safe operating limits.

3. 3

   Inspect the mechanical system for binding, misalignment, or obstructions. Verify correct lubrication of moving parts.

4. 4

   Confirm that the motor parameters (e.g., P300.00-P304.00) are correctly entered into the drive configuration.

5. 5

   Perform a motor insulation resistance test (Megger test) between motor phases and ground, and between phases (terminals U, V, W).
