Setup for Analog Pot input
Note: e steer motor should not respond to this command input because the
Interlock is O. If the steer motor shows any movement (or if the Interlock is
On), stop and resolve the issue; see Preparation for Commissioning, page 29.
a. Move the steer command pots to the Left position (not to the actual phys-
ical stop, but a small amount away, to allow for pot tolerance variation)
and observe the voltage shown in the Monitor
» Command Input » Command
Analog 1 Input variable. Set the parameter Command Analog Left to the observed
voltage.
b. Move the steer command pots to the Center position and observe the voltage
shown in the Command Analog 1 Input variable. Set the parameter Command
Analog Center to the observed voltage.
c. Move the steer command pots to the Right position (not to the actual
physical stop, but a small amount away, to allow for pot tolerance variation)
and observe the voltage shown in the
Command Analog 1 Input variable. Set the
parameter
Command Analog Right to the observed voltage.
d. Set the two fault parameters (
Command Analog Fault Min, and Command Analog
Fault Max). Set these to voltages that will not be reached during normal op-
eration, but will be reached when the steer command inputs become faulty
(e.g., should there be an open or short circuit).
e Command Analog Fault Min setting must be below the minimum voltage
seen on
Command Analog 1 Input when steered to the maximum left or right
positions.
e Command Analog Fault Max setting must be above the maximum voltage
seen on
Command Analog 1 Input when steered to the maximum left or right
positions.
