6.3 Performing motor movements
6.3.1 Reference values via the digital signal inputs
The movement is started and terminated via the digital signal input
START.
The digital signal input F_HIGH allows you to switch between the two ad-
justable velocities.
NOTE: If the reference value is supplied via the analog signal input, ref-
erence values may neither be supplied via the digital signal inputs nor as
external reference values.
Setting velocities The potentiometer f_high allows you to set the value for the fast velocity.
The potentiometer f_low allows you to set the value for the slow velocity.
The adjustable velocity depends on the number of steps.
NOTE: The velocity range is a theoretical value. The actually possible
velocity depends on the motor used.
Setting acceleration and
deceleration
The potentiometer ACC allows you to set the value for the acceleration
ramp. The potentiometer DEC allows you to set the value for the decel-
eration ramp.
