3HAC068055-001 Revision: K

The values for payload and arm load are not consistent with the actual ones.

The value for ambient temperature setting in the controller is not consistent

with the actual operating temperature environment.

The user program may contain too much high acceleration and deceleration

of the joint.

Gravity torque or external forces for the joint can also be too high.

Allow hot parts to cool down.

Verify that the values for payload and arm

load are set correctly.

Verify that the value for ambient temperature

setting in the controller is consistent with the

actual operating temperature environment.

Rewrite the user program to reduce the mo-

tor utilization.
