La AZ-EQ5, AZ-EQ6 si EQ8, PEC-ul este stocat in controlerul RA 

5.2 Permanent Periodic Error Correction

The AZ-EQ5 GT mount is equipped with an index on its R.A. worm. Thus the motor controller can keep track of the current position of the worm. After a proper PEC training routine, in which the training data is stored in the motor controller permanently, a user can start the periodic error correction (PEC) at any time to improve the tracking performance for short focal length astrophotography. A training process is not required in the next observing session (assuming that the polar alignment is always accurate). Thus this is a Permanent Period Error Correction (PPEC). A user can train the mount with manual guiding or auto-guiding. For detailed instructions, please refer to the relevant section in the SynScan hand controller instruction manual.
