Configuring the Ultra5000 Drive Chapter 4
Understanding the Gear
Window The Properties window for the Gear branch looks like this.
Use the Gear window to:
• configure the drive's Gear Ratio. Gearing takes the position data provided
by a master encoder and uses it to generate motion
• monitor status relating to gear-driven motion
You can edit parameters for both an online and an offline Gear branch. However,
you can monitor status and execute direct commands (executed through the
Ultraware interface, rather than through a compiled, loaded and executed
program) only for a Gear branch that is the child of an online drive.
The following parameters can be entered and edited in the Gear window.
Parameter Description
Gear Ratio The number of counts the motor should move for each master
encoder count received (in Motor Counts per Master Count).
Floating point numbers are permitted.
Slew
Gear Slew Enabled – the gear ratio ramps up or ramps down using the
acceleration and deceleration specified below.
Disabled – the acceleration and deceleration are effectively
infinite.
Accel If the gear is enabled while the gear input is in motion, or the
gear ratio is changed to a greater value. The gear ratio ramps up
to the specified value at this rate.
Decel If the gear is disabled while it is in motion, or the gear ratio is
changed to a smaller value. The gear ratio ramps down to the
specified value (or zero if disabling) at this rate.
