Jog Button
This configuration allows a Function key to control the Velocity Setpoint variable and can be either
momentary or maintained The following examples explain the operation of each mode.
If Momentary:
When the switch is pressed the specified value is written to the Velocity Setpoint variable in the
Ultra Drive. When the switch is released, the value zero is written to the variable.
If Maintained:
When the switch is pressed the current value of the Velocity Setpoint variable is read from the
Ultra Drive. If the current value is equal to the specified value then the value zero is written to the
Ultra Drive. If the current value does not match the specified value then the specified value is
written to the Ultra Drive.
Since all four function keys can be configured as Jog Buttons it is possible to have multiple jog speeds and
directions from a single screen. For example you may configure the keys as Fast Jog Forward, Slow Jog Forward,
Fast Jog Reverse, and Slow Jog Reverse.
Notice:
The Jog Button function will not cause movement unless the
Drive is enabled and set for velocity control mode.
