neutral. The displayed Mapped Brake should be = 100% through the range of
motion that is considered max. Contact your Curtis customer support engineer
to resolve any issues about the brake setup before continuing with the setup
procedure.
9 Faults (see Section 8)
Turn the KSI input Off and then On (to clear any parameter change faults)
and use the 1311 to check for faults in the controller. All faults must be cleared
before continuing with the setup procedure. Use Section 8 for help in trouble-
shooting. Contact your Curtis customer support engineer to resolve any issues
about the faults before continuing with the setup procedure.
bk Setting encoder direction and direction of rotation (see page 53)
With the vehicle drive wheels still jacked up, no faults present in the controller,
the interlock Off (as verified in the Monitor
» Inputs menu, page 64), and both the
throttle and brake in neutral (Mapped Throttle = 0% and Mapped Brake = 0%
in the Monitor
» Inputs menu), the encoder direction can be checked. Use
the Monitor » Motor menu (page 68) to view the Motor RPM display. Turn
the motor by hand and observe the sign of Motor RPM. Positive is forward
and negative is reverse. If you get a positive Motor RPM when you rotate the
motor in the forward direction, and a negative Motor RPM when you rotate
the motor in the reverse direction, the Swap Encoder Direction parameter is
correct and should not be changed. If you are getting negative Motor RPM
when rotating the motor forward, the Swap Encoder Direction parameter must
be changed. Cycle KSI power and repeat the procedure until you are satisfied
that the Swap Encoder Direction setting is correctly set. If the vehicle will use
the emergency reverse feature, the reverse direction (negative Motor RPM)
must be correctly selected so that when the Emergency reverse input is active
the motor will rotate in the reverse direction. Contact your Curtis customer
support engineer to resolve any issues about encoder direction or emergency
reverse before continuing with the setup procedure.
Now that you have the encoder direction set correctly, you can test to
see which direction the motor will spin due to how the three phase cables ( U ,
V , and W ) are connected to the motor.
Cycle KSI input Off and then On (to clear any parameter change faults)
and use the 1311 to check for faults in the controller. All faults must be cleared
before continuing with the setup procedure.
Apply the interlock input and verify that the interlock = On (as verified
in the Monitor » Inputs menu).
Then, while keeping the brake in neutral, select a direction and apply
throttle. The motor should begin to turn, but it may turn in the wrong direc-
tion. Observe the direction of rotation of the motor and if it is turning in the
wrong direction return the throttle to neutral, and change the setting of the Swap
Two Phases parameter. Cycle power, turn on interlock, and turn on direction.
Apply throttle and verify that the direction of rotation of the motor matches
