Description
AIN.CUTOFF sets the break frequency in Hz for two cascaded single-pole low-pass filters on
the hardware command input. Since the two poles are cascaded at the same frequency, the -3
dB frequency is 0.64*AIN.CUTOFF in hertz and the 10% to 90% step response rise time is
0.53/AIN.CUTOFF in seconds.
Suggested operating values are as follows:
l Analog torque opmode: 5 kHz
l Analog velocity opmode: 2.5 kHz
l General purpose analog input high resolution: 500 Hz
