Case 2-A. When PG feedback function is used

9.7.2 Case 2

Prepare for installing according to 9.7.1, 1 to 5.

Case 2-B. When PG feedback function is mot used

Preparation is not needed.

Note1) Attach flexible connecting board to the board-A (not to the control board). The image after option attachment becomes as follow.

Flexible connecting board

Connector

Board-A

Control board

Wire-C

Optional add-on cassette

Note2) Do not change the position of the bit switch for PG input (default setting is without PG input) in the option unit (TLS001Z or TLM001Z). If you set at with PG input position, auto-restart function(refer to 6.13.1) dose not work correctly and over-current, overload, over-voltage, etc. trips may occur.

9.7.3 Case 3

Preparation is not needed.

Note) Attach flexible connecting board set with attachment (SBP001Z or SBP002Z) to board-A (not control board).

Refer to attachment image in case 2-B.
