MTA Staten Island Railway Automatic Speed Control: A hybrid of the PRR/LIRR systems and Rapid Transit power-frequency cab code. The ATC applies service braking in response to overspeed conditions. 75-120-180-270 are used as speed commands. Zero code is used for stop rather than restricting, which is 50PPM. 420 is used as a latch-out.

An electronic speed control follows a speed reference signal (derived from a throttle lever, joystick, or other manual input) and varies the switching rate of a network of field effect transistors (FETs). [1] By adjusting the duty cycle or switching frequency of the transistors, the speed of the motor is changed. The rapid switching of the ...
