# The main asyn motor record. Some fields are populated from the substitution
# files via macros:
# - $(INSTR): Name of the instrument, e.g. "SQ:SINQTEST:"
# - $(M): Name of the motor in EPICS, e.g. "lin1"
# - $(DESC): Short description of the motor
# - $(DIR): This value is usually set to "Pos". If the motor axis direction
# should be inverted, this value can be set to "Neg"
# - $(CONTROLLER): Name of the motor controller, e.g. "mcu1"
# - $(AXIS): Number of the axis, e.g. "1"
# - $(MRES): Motor record resolution. See the README.md for a detailed discussion
# - $(EGU): Engineering units. In case of a rotary axis, this is "degree", in
# case of a linear axis this is "mm".
