APPENDIX A:  GLOSSARY

The operating PWM frequency is shifted to 1.5 kHz when the controller is 
operating in the overtemperature range.

Overvoltage protection

Overvoltage resets the microprocessor, inhibits PWM, and opens the contac-
tors, thereby shutting down the controller. Overvoltage can result during bat-
tery  charging  or  from  an  improperly  wired  controller.  Controller  operation 
resumes when the voltage is brought within the acceptable range. The cutoff 
voltage and re-enable voltage are percentages of the battery voltage, and are 
set at the factory.

Plug braking

Plug braking takes place when a series motor is driven electrically in a direction 
opposite from the direction it is turning. The 1207B controls the field current 
to obtain smooth and controlled plug braking torque. During plug braking, 
the maximum current limit is automatically changed to the plug current limit, 
and the PWM frequency is changed to 1.5 kHz.  Note:  Plug current limit on 
the 1207B controls the field current. The armature current in plug mode will 
be higher than the field current.

There are two types of plug braking control — fixed and variable. The fixed 

plug current limit is set to a fixed level. The variable plug current limit varies 
the current limit to correspond to the throttle position. 

The plug current limits in Mode 1 and in Mode 2 are independently ad-

justable via the handheld programmer. 

PWM

Pulse width modulation (PWM), also called “chopping,” is a technique that 
switches battery voltage to the motor on and off very quickly, thereby control-
ling the speed of the motor. Curtis 1200 series controllers use high frequency 
PWM—15 kHz—which permits silent, efficient operation.

Quick-start 

Upon receiving a quick throttle demand from neutral, the controller will exceed 
normal  acceleration  momentarily  in  order  to  overcome  inertia. The  “quick-
start” algorithm is applied each time the vehicle passes through neutral and is 
not in plug mode. If the vehicle is in plug, the quick-start function is disabled, 
allowing normal plug braking to occur.

The quick-start throttle factor is adjustable via the handheld programmer.
