The power stage is overloaded. The overload level has been increased up to 100 %. Probably the diagnostic message 8129 Power stage load high has been triggered before.

In this case, unlike diagnostic message 8107 Overcurrent, switch off does not occur as soon as the current threshold has been exceeded. The thermal overload of the device is observed for a specific length of time. The current overload of the drive is shown in the parameter DriveOverload.

Cause

Solution

The power stage is overloaded.

oVerify and correct if necessary the combination motor/drive.

oVerify and correct if necessary the calculation of motor and drive.

oDrive the system at a slower speed.

The motor brake is not open.

Verify and correct if necessary the wiring of the motor brake (voltage reversal, cable break, …).

Detected hardware error: Servo amplifier inoperable.

Replace the servo amplifier.

Valid only for Lexium 52: The device is operated without a power choke.

Connect power choke and set the parameter MainsChokeConnected to on/1.
