FM-3 Programming Module Reference Manual
Brake Operation
MG motor brake operation is controlled by the Brake Release and Brake Control destinations.
These destinations can be used together to control the state of the Brake source. The table
below shows the relationship between the Brake sources and destinations (see “Diagnostic
Display”).
Note
No motion should be commanded while the brake is engaged.
Brake Release
The Brake Release destination function will release the brake under all conditions. When this
function is active, the Brake output will be on (that is, release brake). This function overrides
all other brake control, thus allowing the brake to be released while a fault is active or the
power stage is disabled. See also Brake source function.
Brake Control
The Brake destination function, when active, will engage the brake unless overridden by the
Brake Release function. This function lets you externally engage the brake while allowing the
drive to also control the brake during fault and disabled conditions.
Brake
The Brake source function is used to control the motor holding brake. If the Brake function
is off, the brake is mechanically engaged. When the brake is engaged, the diagnostic display
on the front of the drive will display a “b”.
The drive outputs are limited to 150 mA capacity, therefore, a suppressed relay is required to
control motor coil. EMERSON Motion Control offers a relay, model # BRM-1.
