Glossary
Acceleration The rate at which speed increases, in counts/sec 2 .
Advanced controller A controller with a more complex structure than a
simple PI or PID. It can include several notch filters,
low pass filter, poles and zeros.
Application continuous current The maximum current, in amperes, that can be used by
the specific application. This value must be equal to or
less than the continuous stall current defined by the
manufacturer for the selected motor.
Application peak current The maximum short-term current, in amperes, to be
used with the specific application during the design
phase of auto-tuning. This value must be equal to or
less than the peak current defined by the driver
manufacturer.
Application speed limit The maximum motor speed, in RPM or meters per
second, used for the application. This value must be
equal to or less than the maximum mechanical speed
defined by the motor manufacturer.
Bandwidth The difference, in hertz, between the highest and
lowest level of a frequency range. In a standard
feedback system, responses to reference commands at
low frequencies are probably large; however, at high
frequencies, they decrease. It is customary to look at
the frequency where the response command amplitude
drops to 70% in amplitude, compared to a low
frequency response as a split frequency between good
response and bad response. This frequency is used as a
figure of merit for the system and is called the system
bandwidth.
Baud rate The rate at which digital data is transmitted, in bits per
second.
Bounded motion For auto-tuning purposes, a mode in which the motor
motion is limited to movement around a selected fixed
point. This mode is used with linear motors and with
rotating motors whose shafts must remain within
specified angle boundaries.
Coil length The distance, in millimeters, that the motor travels
during one electrical revolution. This value is normally
listed in the motor datasheet.
