2.5Mechanical brake output
2-19
If the mechanical brake is operated while the servo motor is rotating, the mechanical brake
may become abnormally worn or damaged and result in equipment failure.
Releasing the brake on the vertical axis may cause the equipment to fall due to its own
weight. Be careful on its falling when releasing the brake.
Operating the brake while the motor is rotating may cause the brake to be worn or
damaged, and result in a damage to the motor bearing or encoder.
Pr4.59 is a parameter of always effective attribute. When changing the setting value,
employ caution not to cause abnormal operation of the brake.
This parameter sets up the signal which is output from the mechanical brake output
(BRK+/BRK-). It will not change the output signal from the I/O connector. To control the
mechanical brake from the I/O connector, assign the desired brake release signal.
Err17.0 "Mechanical brake circuit voltage protection" or Err17.1 "Mechanical brake circuit
overload protection" will occur if an error occurs in the mechanical brake circuit.
