6.3.5. Setting Up Command Waveform

You can set up the command waveform to generate repeating waveforms that allow you to examine the quality of control.
  1. Enter values for the parameters.
    Table 4.  Command Waveform Parameters
    Parameter Value Description
    Waveform type Sine, Triangle, Square, Sawtooth The shape of the repeating waveform.
    Period (samples) 2 to 32768 Period of the waveform, in 16 kHz samples. For example, 2000 is equivalent to 8 Hz.
    Position amplitude -180 to +180 +/- amplitude of the waveform, if running in position control. Negative values create a 180 degree phase shift.
    Speed amplitude (rpm) -2048 to +2048 +/- amplitude of the waveform, if running in speed control. Negative values create a 180 degree phase shift.
    On/Off On or Off Switches the waveform on or off. The waveform is superimposed on the speed or position set points from the General tab.
  2. Click Update waveform.
