5 — INITIAL SETUP
the AC Motor Characterization Procedure is used, it can determine the encoder
steps (but only for encoders with 32, 64, or 80 ppm).
Setting the Encoder Steps parameter improperly may cause vehicle
malfunction, including uncommanded drive.
2 Motor temperature sensor (see page 54)
Set the Sensor Type parameter to the predefined type (1–5) that corresponds
to your motor temperature sensor. Typically, the motor temperature sensor will
be a thermistor that should be connected from Analog 2 (pin 8) to ground
(pin 7) as shown on page 12.
To check whether the parameter settings and the motor thermistor connec-
tions yield the correct motor temperature, read the Temperature value displayed
in the 1311’s Monitor
» Motor menu (page 68). This is typically done when
the motor has not been run for many hours, to ensure the motor is at a known
(room) temperature. If the 1311 does not display the correct motor temperature,
contact your Curtis customer support engineer for help. If the correct motor
temperature is not displayed, or if there is no motor temperature sensor, this
setup procedure can continue only if the Sensor Enable is set to Off.
If the 1311 displays the correct motor temperature, continue with the
procedure and set up the Sensor Enable, Temperature Hot, and Temperature
Max parameters.
3 Current limits (see page 39)
The Drive, Regen, Brake, EMR, and Interlock Current Limit parameters are a
percentage of the controller’s full rated current. The controller’s full rated current
is printed on the label of the controller. Set the five current limit parameters
to your desired values.
4 Battery (see page 55)
Set the Nominal Voltage parameter to match the nominal battery pack voltage
of your system.
5 Main contactor (see page 48)
Set up the parameters in the Main Contactor Menu.
6 EM brake (see pages 46–47)
Set up the parameters in the EM Brake Menu.
7 Throttle (see pages 13–17 and 43–44)
Before the throttle can be set up the interlock must be verified as Off, by read-
ing the Interlock value displayed in the Monitor
» Inputs menu (page 64). If
the 1311 indicates the interlock is On, review how you set the Interlock Type
parameter (Main Contactor Menu) and turn the interlock off. Verify that the
1311 displays that the interlock is now Off. Contact your Curtis customer
