5-12 Ultra1500 Application Examples
pulse train output from the MicroLogix controller is limited to 20 kHz, the
gear ratio will need to be set so that the maximum motor speed of the
application requires less than a 20 kHz input frequency.
For example, a TL-Series motor with 131,072 counts/revolution and a
maximum application speed of 5000 rpm will result in a motor encoder
frequency of 10,922,667 counts/second. To maximize resolution, the Gear
Ratio parameter should be set to 15:8192, as shown in the following equation.
Configuring the MicroLogix Controller
This procedure assumes that you have finished wiring and configuring your
Ultra1500 drive. For greater detail on the RSLogix500 software and
MicroLogix 1200 and MicroLogix 1500 controllers, refer to the table below for
the appropriate publication.
The motion functionality of the MicroLogix 1200/1500 system is embedded
in the Pulse Train Output (PTO) feature, which allows a frequency-controlled
pulse stream to be output from the controller. In the RSLogix500 software, the
