Tuning
Tritex default gains are set to work out of the box for many applications, for those applications
that require tuning two parameters are provided on the Tuning page.
Tuning Adjustments
The drive’s proprietary motion controls algorithms have been designed to reduce the number of
tuning parameters for the customer. There are only 2 parameters; Position and Speed Stiffness.
If the drive is online changes to the gain parameters take effect immediately, however they will
not be save in non volatile memory until a down load is performed.
Positional Stiffness
: Determines how tightly position is tracked, both during motion and at a
stop. Too high of a setting can cause instability and overshooting of position. Too low of a
setting will cause sluggish motion. For systems with backlash or compliance the Positional
Stiffness will need to be lower.
Speed Stiffness
: Determines how tightly the velocity profile is followed during a move. It has no
affect at zero velocity. Too high of a setting can cause erratic motion at low speed. Systems
with higher friction loads or high constant force loads usually require the speed stiffness to be
turned up, so the move profile is more closely followed, if the speed falls behind during the
move, the excess following error can cause overshoot at the end of the move.
