Jog Frequency Error
Allen-Bradley · MicroLogix 1400 Programmable Controllers
What does 6 mean?
The jog frequency (JF) value specified for the PTOX instruction is less than 0 or greater than 100,000 pulses per second. This error faults the controller and indicates an invalid frequency parameter for jog operations. It can be cleared by logic within the User Fault Routine.
Common Causes
- Jog frequency (JF) parameter set to an out-of-range value (i.e., less than 0 or greater than 100,000).
- Incorrect calculation or direct input of an invalid jog frequency parameter in the PTOX instruction.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Adjust the jog frequency (JF) value in the PTOX instruction to be within the valid range of 0 to 100,000.
- 2
Review the program logic that writes to the JF parameter to ensure it calculates and sets a valid frequency.
- 3
Clear the fault using the User Fault Routine or by cycling power after correcting the JF value.
