amperes
analog-to-digital
treat the target position loaded as position relative to zero (0) while making
a move
position relative to zero
a measurement of the change in velocity as a function of time. Acceleration
and deceleration describes the period when velocity is changing from one
value to another.
a signal is active when its value goes high (1)
a signal is active when its value goes low (0)
analog-to-digital converter
character code that identifies a specific location (or series of locations)
in memory or on a host PC bus system
the drive that delivers power to operate the motor in response to low level
control signals. In general, the amplifier is designed to operate with a
particular motor type—you cannot use a stepper drive to operate a DC
brush motor, for instance
12-bit analog ADC input
