5.5.2 Performing a Move
Once the move settings are correct the mechanism
to be moved shold also be checked to ensure it is
ready to move. It is especially important to make sure
the direction is set correctly. In some cases it is wise
to select
alternate
to avoid running the mechanism
into a hard stop. Select the
Sample Once
button.
Click the
Start
button and observe the results.
If problems occurred during the move an Alarm
indicating a Fault or Warning may be displayed and need to be cleared. The drive may be left
disabled until the Alarm is cleared and the Enable button is clicked.
Note: Clicking the Alarm Reset button and then the Enable button will clear a fault and
enable the drive.
Now the motion parameters will need to be adjusted to achieve the desired move profile. The
move can be repeated by clicking the
Start
button. If the drive continues to fault it is possible the
maximum current or position error parameters are being exceeded. These can be set in the
Drive
Configuration
tab.
The current setting can be checked by selecting
Current
in one of the Plot lists and clicking
Start
again to see what current is being required of the
drive during a move. The current profile of the move
will be displayed and may give a clue as to why a
fault is occurring.
5.5.3 Adjusting tuning parameters
The two primary parameters for a Timed move are
the
Proportional
(VP) &
Integral
(VI) gain parameters of the velocity loop.
Starting with these two terms is a good way to begin tuning as they are the minimum required
terms in Velocity Loop tuning. The
FF Gain
is not
required but adds to the tuning, this will be discussed
later.
Note 1:
The
Disable
button in the Menu bar of the
SSM Quick Tuner window under the label
Servo
will
disable the motor should a serious problem occur.
Note 2:
The Gain values can be changed at any
time during the tuning process. When the SSM
Quick Tuner software detects a change in the value
it will automatically download the new value. The
Download
button in the upper right of the window
does not need to be clicked.
Once a successful move has been accomplished (no
fault occurs) the motor is ready for tuning. Adjust the
