PTO Jog Frequency (JF)
The PTO JF (Jog Frequency) variable defines the frequency of the PTO
output during all Jog phases. This value is typically determined by the
type of device that is being driven, the mechanics of the application, or
the device/components being moved). In the MicroLogix 1100 Series A
controller, the data less than zero or greater than 20,000 generates a PTO
error. However, in the MicroLogix 1100 Series B controller, the data less
than zero or greater than 40,000 generates a PTO error.

ATTENTION
In order to use 40kHz PTO and PWM with a prior version
of RSLogix 500 (version 7.10 or lower), variable type
change process is required (unsigned integer to signed
integer). Refer to PTO and PWM function file changes in
Series B Controller on page 569 in
Appendix F How to Use
40kHz PTO/PWM of MicroLogix 1100 Series B Controller
for more information.
