C.5.1: Input Shaping Window 
The Input Shaping tab opens a window that shows Input Shaping choices and a 
representative Time and Amplitude table. Modify the settings as needed and press Apply. 
Type as well as Frequency and Damping Rate may be adjusted. Overcurrent is adjustable 
when a Negative Zero Vibration or a Negative Zero Vibration and Derivative filter is 
chosen. If Custom is chosen as the Type, Time and Amplitude may be set manually. 
C.5.2: Input Shaping Types 
In CME 2 input shaping type options are:
Type 
Description 
Zero Vibration 
Single step inputs are replaced with two step inputs of smaller magnitude. One 
of which is delayed by one-half the period of vibration. Sensitive to some 
modeling errors. 
Zero Vibration and 
Derivative 
A zero derivative (of the vibration) constraint is added to Zero Vibration 
impulse shaping, thereby reducing modeling errors. 
Negative Zero Vibration 
Faster than positive input shaping (Zero Vibration, and Zero Vibration and 
Derivative), but may magnify high frequency vibrations. 
Negative Zero Vibration 
and Derivative 
A zero derivative (of the vibration) constraint is added to Negative Zero 
Vibration impulse shaping. 
Custom 
Time and Amplitude can be set manually.
