Speed Selection

Speed Source Priority

The 1336VT drive can receive speed or frequency commands from a
number of sources. These sources have been given various priorities so that
speed source selection may be defined and understood. The numbered
speed sources shown below are listed by priority and how they are
selected.

Priority 1 - Jog Speed

Jog may be selected if the drive is not running. Jog is selected by a Local
or Remote Control Panel Jog pushbutton, Terminal 22 of TB3, or by serial
input programming from an Allen-Bradley PLC. All Programming and
Display Panels will display Pr = -6 when jog is selected.

Priority 2 - Preset Speed 1Ć7

Preset speeds are selected by combinations of inputs at Terminals 24 and
26 of TB3 or by serial input programming from an Allen-Bradley PLC.
