MAXIMUS 7 OPERATOR’S MANUAL
August 17, 2016
The SERVO MODES AND CONTROLS group shows enable, disable and test status of the axes and helps
to perform some testing.
The first column is the enable column. All enabled axes marked by green squares. Click on a disable
square to disable the desired axis. If you want to test torque disable all axes! (Click on “Disable All”)
Then click on the last column (Test) of the axis to be tested and then enter the desired current in AMPs
in the field to the right. (CURRENT COMMANDS) Maximum 20 AMPs, that will brake arms! Restrain
the axis before start, enter 1 or 2 AMPs only and gradually increase it if needed. The axis can be fixed by
a torque meter to measure torque. Do not hold high currents for a long time (10-15 seconds) it will heat
up drivers unnecessarily.
The SYSTEM STATUS group on the bottom right of the window shows the electronic module’s connection
status. Everything (except the LENS) must be green for correct operation.
6.8 Maintenance Tool, Servo Parameters tab
The big rectangular buttons to the right are commands to save or reload parameter tables.
LOAD:
Loads the current parameter table from the nonvolatile RAM.
STORE:
Stores the current parameter table into the nonvolatile RAM, use this to make your
changes permanent.
LOAD DEFAULT: Set this parameter table back to factory default. If you want it to be permanent click
STORE too.
“Initialize All Parameters”:
Set
all
parameter tables (general too) to factory default it will save them in the
nonvolatile RAM also, don’t have to click STORE. For safety do it twice. The zero
positions of all axes must be checked after this command before enabling the
gimbal!
In all servo tables the parameter “Axis MGain” is the master scaling of all the servo filters in that specific
loop, use it to balance the loops. If these parameters are correctly balanced then the “Master gain” (a general
parameter) that can be adjusted from the console with F4 key will work correctly.
Parameters that are not in green fields can not be changed. To change a parameter click on it’s field and
enter the new value in the “New value” box with the keyboard. Press the Enter key.
To select another axis parameter table select it using the drop-down list at the SERVO label. The lens tables
do nothing this time.
