An optional holding brake built-in to motor provides protection against unwanted
motion when the power is cut and in case of error. If the brake is mounted on the axis
mechanism and not directly on the shaft, note that undesirably severe torsional
forces may occur on sudden engagement of the brake.
The P 125[0] - MPRO_OUTPUT_FS_MOTOR_BRAKE function selector can be
used to select any function (similar to those for the digital outputs) for the motor
brake output. However, the special motor brake control section hardware will be
used for the selected function.
However, when using a motor brake with P 125[0] - MPRO_OUTPUT_FS_
MOTOR_BRAKE = BRAKE(2), the criteria for braking need to be defined. This
criteria can consist of a variety of states, limits, threshold values, input signals, and
fieldbus commands.

P 748[0] - MON_MotorBrkGuard can be used to activate a monitoring mechanism at
the motor brake output that will monitor both wire breaks and current. The brake
function can also be used in the other digital outputs, though without current and
wire break monitoring.
If the output is set to BRAKE(2), the brake can be configured with the “Options...”
button (see Section "Motor brake details" on page 309).
