Set the wrist load in the parameters to the actual value mounted. Loading from PROM defaults this to maximum. This fault is common on a 6000/2.4-150 with nothing mounted on the wrist. The robot overreacts when the brakes open as it is trying to catch and hold 150kg.

Depends on your firmware. PARAM > CHANGE > keep pressing SCAN until LOAD > WRIST
Should find it explained in the Parameters section of the Product Manual.

Ok thanks ,

do any off the drive boards inside the cabinet (6) have a red led when this happens?

The motor overload error is most likely the PTC connection in one of the motors.
A physical jamming of an axis or any movement anomaly will report a servo Error.
You can trace the PTC connections at the power cable socket at the base of the robot. C1 and C3 connection is for Axis 1. C4 and C5 is axis 2, C6 and C7 is axis 3, C8 and C9 is axis 4, C10 and C11 is axis 5 and C12 and C2 is axis 6. You should have continuity between C1 and C2 as all the PTCs are connected in series.

Some larger robots run parallel wires for each motor phase on the major axes to share current load.
Which manipulator model is this?

Did you download the IRB1500 manual found >here< in the manuals section?
