5.11.6 Access without MacTalk
If MacTalk is not used for setting up parameters/registers related to the brake feature it
must be done as follows.
The motor contains a number of registers which can be accessed from various protocols
depending which options the motor has.
Protocols available are for example Ethernet (EthernetIP, PROFINET etc.) and CAN-
open, Modbus or the MacTalk protocol.
Each field in MacTalk described earlier in this chapter is accessing a register in the motor.
The registers that are relevant for operating the brake are:
R25
R124 SETUP_BITS
Connect an external brake
R179 BRAKE
.
