PQ, FQ, and RQ-

Axes

Objective:

Given a CP-7-series machine, technical

documentation and required tools,

remove, replace and calibrate the PQ, FQ

and RQ-motors to FUJI specifications.

4.1 Replacing the Q-Motors

PQ Motor

The FQ-motor (refer to figure below) is responsible for rotating the placing shaft at

station 2 in increments of +90° or -90°, depending on the part placing angle

specified in the production program.

Any failure of the PQ-axis will result in inaccurate results when vision processed

at station 5, and subsequently offset placing angle.

FQ-Motor

The FQ-motor (refer to figure below) is responsible for rotating the placing shaft at

station 8 in at the compliment of the rotational angle performed at station 2,

depending on the placing angle specified in the production program.

Any failure of the FQ-axis will result in inaccurate component placing angle at

station 9.

RQ-Motor

The RQ-motor (refer to figure below) is responsible for rotating the placing shaft at

station 10 minus the sum of both rotations at PQ and FQ.

Any failure of the RQ-axis will result in a station 13 Nozzle prechange check.

Some examples of possible reasons for recalibration are:

- Damage or slippage of the timing belt which connects the Q-axes motor

gear and the axis itself.

- After replacement of the Q-motor.
