Interconnect Diagrams A-15
The example below shows 1394 series C axis modules with internal
brake filtering. Each axis is connected to a motor with a brake rated at
less than 1A. A separate pilot relay is not required. Motor brakes that
do not require a pilot relay are shown in the table below.
Note: Suppression devices and pilot relays impact motor brake
response time.
