A configuration for the Universal Stepper card from Pico systems. This configuration includes motion connections and an IO set for handling estop within HAL. ini file parameters INPUT_SCALE are for the encoder counts/user unit, OUTPUT_SCALE is the scaling for the drive steps per user unit (which can be different).

A configuration for the PPMC board set from Pico
systems. This configuration includes motion connections
and an IO set for handling estop within HAL. The IO
configuration in ppmc_io.hal DOES include signal
connections for some bridgeportio like signal handling.
This configs set includes the option for encoder
velocity estimation via timestamping, and tells how to
change the encoder digital filter frequency.

# gearing/screw pitch. For example:
#
# Power supply voltage 50V
# Motor RPM/V 1000RPM/24V
# Gearing: 2 motor revs per 1 screw rev
# Screw pitch: 0.2" per turn
#
# Max motor speed = 50V * 1000RPM/24V = 2083 RPM
# Max screw speed = 2083RPM * 1(screw)/2(motor) = 1041RPM
# Max table speed = 1041RPM * 0.2"/turn = 208 in/min
# Max table speed = 208 in/min / 60 seconds = 3.47 inches/sec

# Gearing: 2 motor revs per 1 screw rev

# Max motor speed = 50V * 1000RPM/24V = 2083 RPM
# Max screw speed = 2083RPM * 1(screw)/2(motor) = 1041RPM
# Max table speed = 1041RPM * 0.2"/turn = 208 in/min

A configuration for the Universal PWM COntroller board from Pico systems. This configuration includes motion connections and an IO set for handling estop within HAL. The IO configuration in univpwm_io.hal does not include signal connections for other bridgeportio like signal handling. This version takes advantage of the new UPC feature of velocity estimation to provide smoother motion, especially the functioning of the D term of the PID component.

# issue may be fixed, and PWM_OUTPUT_SCALE will go away.
# Scaling: The PWM_OUTPUT_SCALE should be the speed
# in UNITS/second (inches/sec or mm/sec) that would be
# reached if the PWM duty cycle was 100%. It depends on
# the power supply voltage, motor RPM/Volt factor, and
# gearing/screw pitch. For example:
#
# Power supply voltage 50V
# Motor RPM/V 1000RPM/24V
# Gearing: 2 motor revs per 1 screw rev
# Screw pitch: 0.2" per turn
#
# Max motor speed = 50V * 1000RPM/24V = 2083 RPM
# Max screw speed = 2083RPM * 1(screw)/2(motor) = 1041RPM
# Max table speed = 1041RPM * 0.2"/turn = 208 in/min
# Max table speed = 208 in/min / 60 seconds = 3.47 inches/sec
#
# Since max speed is reached at 100% duty cycle, PWM_OUTPUT_SCALE
# should be 3.47
