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.
