Extension cable

(1)Extension bases unit of up to seven stages can be used.

(2)Do not use extension cable longer than an overall extension length of 13.2m(43.31ft.).

(3)When using an extension cable, do not bind it together with the main circuit (high voltage and heavy current) line or do not lay down them closely to each other.

(4)When setting the No. of the expansion stages, set it in the ascending order so that the same

No. is not set simultaneously by two extension base units.

(5) When Q5B, Q6B and QA1S6B types of extension base units are mixed, first connect the Q5B, Q6B type and then connect the QA1S6B type.

When setting the No. of the extension stages, set it from Q5B/Q6B in order.

NotesAlthough there are no particular restrictions in the order of the installation of the Q5B and Q6B, refer to Section 6.6 for usability.

(6)Connect the extension cable from OUT of the extension cable connector of the base unit to IN of the extension base unit on the next stage.

(7)If 65 or more modules are installed, an error will occur.

(8)When the GOT is bus-connected, it occupies one extension stage and one slot.

(9)The High Performance model QCPU processes the GOT as a 16-point intelligent function module. Hence, connecting one GOT decreases 16 points available for the base unit.

(10)Q61SP cannot be used for the power supply module.

Use Q61P-A1, Q61P-A2, Q62P, or Q64P for the power supply module.
