The holding brakes of J Series servo motors are fail-safe brakes, which means they are engaged
when no power is applied to the brake. When setting up a servo drive in QuickTuner™ , 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 engaging the brake
when a motor disable command is issued.
