in the software. If your application has unusually
high bandwidth requirements or your servo
amplifier functions as a velocity regulator only, use
the velocity mode.
Step 10. Fasten the field wires from the drive reference and
power supply to the terminal strip. Typical field
connections are shown in figure 3.6 and 3.7.
Step 11. Connect the watchdog outputs on the terminal
strip into the drive enable circuit. This signal is
used to disable the servo if a problem develops in
the module. It must be installed in combination
with a hardwired E-stop circuit as well as a pair of
contacts that are controlled from a digital output
from DCS or AutoMax software. Typical field
connections are shown in figure 3.7.
