Step 5. Unidrive UD77 Network configuration

The next step is to power up each Unidrive, one at a time, and set the Menu 20
parameters to the values that will set the MAC-ID and data rates to the values expected
for this project.
To start and stop the Unidrive(s), the SLC program must write to the proper control and
mask bits in the Unidrive "control word". Details describing the use of the Unidrive's
"control word" and "status word" is to be found in the "User Guide DeviceNet
UD77/MD25 Option Cards for the Unidrive and Mentor ll".
Power up the Unidrive with the terminator resistor and set the following Menu 20
parameters to the proper values:
Unidrive #1
Parameter
#20.01
#20.02
#20.03
#20.04
#20.05
#20.06
