The holding brakes of M Series servo motors are fail-safe brakes, which means they are en-
gaged when no power is applied to the brake. When setting up a servo drive in Quick Tuner,
be sure to set the Brake output options in the “Inputs-Outputs” tab as shown in the diagram
below. Make sure to select the check box for “Automatically release brake when moving by”
and selecting the radio button “closing the Brake output”.
The engaging and disengaging of the brake is done automatically by the servo drive. When
the drive is enabled and not faulted the brake will be disengaged. When the drive is disabled
and/or faulted the brake will be engaged.
There are two time delays associated with the Brake output function which are also set in
Quick Tuner (see diagram above). The first time delay controls how long the drive will delay
a move command if the move command immediately follows the disengagement of the brake.
The second time delay controls how long the drive will delay disabling the motor after engag-
ing the brake when a motor disable command is issued.
