#%NAME%
# Macros to control a KEPCO Bipolar amplifier powersupply connected via GPIB line.
#%DESCRIPTION%
# This macro file allows to connect a kepco to macro motors in SPEC.
#
# %BR%Controllers currently supported are:
#%DL%
#%DT%kepco BOP 50-8M (GPIB)%DD%
#%XDL%
#
# For debug purpose mainly, it's also possible to configure a macro
# counter that will read the position of a kepco axis. But to avoid
# duplicating parameters, the counter has no parameter and takes them
# from its corresponding macro motor. In order to guess the motor
# to use, the name of the counter must be the same as the motor with
# %B%\"_c\"%B% added at the end.
# For instance: %B%\"nnn_x_c\"%B% for %B%\"nnn_x\"%B%
#

#
#%SETUP%
# In order to configure a macro motor:
# %DL%
# %DT% 1)
# You must have a "MOTORS" defined with:
# %BR%
# %DL%
# %DT% DEVICE
# set to "kepco"
# %DT% TYPE
# set to "Macro Motor"
# %DT% ADDR
# set to the GPIB_Address of the controller
# %DT% NUM
# must be set also
# %XDL%
# %DT% 2)
# Per kepco axis you must define a motor with:
# %BR%
# %DL%
# %DT% Controller
# set to "MAC_MOT"
# %DT% Unit
# field must be set to the "MOTOR" entry.
# %XDL%
# %DT% 3)
# In the config file add for %B%each%B% motor (%B%WARNING%B%: these
# parameters are critical and can damage your hardware if wrong. They
# are specific to each axis and not to the controller. Therefore
# check with Electronics Group the value and %B%DO%B% %B%NOT%B%
# copy/paste these values)
# %BR%
# %DL%
# %DT%MOTPAR:source = vout|iout
# Voltage source or Intensity source pseudo motor
# %DT%MOTPAR:nada =
# %XDL%
#
# %XDL%
#
# In order to configure a macro counter:
# %DL%
# %DT% 1)
# You must have a "SCALERS" defined with:
# %BR%
# %DL%
# %DT% DEVICE
# set to "kepco_c"
# %DT% TYPE
# set to "Macro Counter"
# %DT% NUM
# must be set also
# %XDL%
# %DT% 2)
# Per kepco axis you must define a counter with:
# %BR%
# %DL%
# %DT% Device
# set to "MAC_CNT"
# %DT% Mnemonic
# must the motor mne plus "_c"
