7.1.4.2. Brake Method
The Brake Method pull-down box lists all the holding brake methods available for the module. Normal is
the default setting upon completion of the Auto-Configuration Procedure. The new settings are downloaded
to the selected Node upon selecting a new item from the list.
In this example, clicking Set All will
download the selected setting to the Left
MDR of all modules entered in the range of
Nodes at the top of the main screen in the
From Node # / To Node # boxes. If for
example these boxes had the values of 1
and 6; changing the selection in the Brake
Method pull down will change Node 1 and
clicking Set All will change Nodes 2 thru 6
to the same setting as Node 1
Method >Description
Normal
Once the controls have decelerated the rotor to a stop, the motor coil are internally connected. The
permanent magnet forces in the rotor and the mechanical inertia of the gearbox holds the rotor in
place. This is the MDR industry standard holding brake method and is often termed short circuit or
shunt. Normal is the default factory setting for all module zones from the Auto-Configuration
Procedure
Free
Once the controls have decelerated the rotor to a stop, the motor coils are internally disconnected
and only the mechanical gearbox inertia holds the rotor in place
Servo
Brake
When the controls have decelerated the rotor to a stop, the processor notes the Hall Effect sensor
status. If the Hall Effect sensor status changes indicating a change in position of the rotor, the
controls will inject current into the motor coils in the proper sequence to move the rotor back to its
original stop position

Servo Brake function utilizes motor power and depending on the torque demanded by the
motor to hold the load the potential for heat build-up exists
