4 — PROGRAMMABLE PARAMETERS
ese controllers have a number of parameters that can be programmed using a Curtis 1313 handheld
programmer or 1314 PC Programming Station. e programmable parameters allow the vehicle’s
performance to be customized to t the needs of specic applications.
PROGRAMMING MENUS
e programmable parameters are grouped into nested hierarchical menus, as shown in Table 3.
Motor Response Tuning
Motor response characteristics can be tuned through speed control or through torque control,
depending on the application. Use the Control Mode Select parameter (page 35) to select which
tuning mode to use:
• Speed Mode Express
• Speed Mode
• Torque Mode.
Speed Mode Express is a simplied version of Speed Mode with a reduced set of parameters that is
adequate for most speed-controlled applications.
Use Speed Mode or Speed Mode Express for applications where throttle input corresponds to motor
speed output.
Use Torque Mode for applications where throttle input corresponds to motor torque output.
Note: Tune using torque control or speed control, but not both. For example, if adjusting a torque
control parameter while Speed Mode or Speed Mode Express has been selected as the tuning mode,
the programmer will show the new setting but it will have no eect.
We strongly urge reading Chapter 7, Initial Setup, before adjusting any of the parameters.
Even if opting to leave most of the parameters at their default settings, it is imperative that the
procedures outlined in Chapter 7 are performed (completed), which set up the basic system
characteristics for an application.
Parameter Change Faults
Parameters marked [PCF] in the menu charts will set a Parameter Change Fault (code 49) if they are
changed while the motor bridge is enabled (interlock = On). Although the parameter will be changed,
the fault will prevent motor control functions until the fault is cleared by cycling the keyswitch.
If the motor bridge is disabled (interlock = O ), changing these parameters will not cause a fault
and the changes will take eect immediately.
