Error ID: 4027, 4040, 4261, 4451
One of the motors of the transport assembly has drawn excessive current, 
causing the motor to become too hot. The processor has switched off the 
motor to prevent damage to the motor.
Motor identification:
• Motor 0 temperature: X- axis motor.
• Motor 1 temperature: Z- axis motor.
• Motor 2 temperature: Theta motor.
The processor monitors the current drawn by each motor and the time the 
motor is drawing current. The current drawn by the motors is dependent 
on the load on each motor (friction, mass of components etc.). If the 
current drawn is too high, or the time the motor draws current is too 
long, the error message is generated.
Probable cause Suggested actions
1 Mechanical obstruction.
Ensure unobstructed movement of the 
transport assembly.
2 High friction in the transport assembly.

Wait at least 10 minutes before switching on 
again.
