Start Up Introduction

In order to provide you with the most reliable Drive and Bypass unit available, and to avoid any extra costs related to
loss or reduction of warranty coverage, an authorized Yaskawa service representative should complete this start up
procedure. Please complete the checklist in this document and maintain it in a secured location. Should you have a
need to contact Yaskawa in the future, technical service personnel may request information from this document.

Procedures within this document assume that start up is being accomplished by a Yaskawa authorized service person
who has training on the product and is capable of working through the detailed steps with power applied to the
Bypass unit while the enclosure door is open.

In this Start-Up chapter, when referring to the keypad display, the complete description of the parameter setting
choices are presented for clarity purposes. For example, one of the setting choices for parameter b1-02 is “1: termi-
nals.” Keep in mind that on the LED keypad display (option T), only the number of the choice will be shown. The
LCD keypad display (option Y) is required to see the complete description.

The Safety Interlock Circuit at Power Up

On power up the E7B_ _ _T or E7B_ _ _Y will display a red “Safety Open” LED in the “System Status” area of the
front control panel if a normally closed “Safety Circuit” has not been installed between TB1-1 and TB1-9 on PCB A2.
This condition will prevent Drive or Bypass operation.

One of the following three items needs to be done prior to start-up:

1)

Install an NC “Safety Circuit” between TB1-1 and TB1-9 on PCB A2.

2)

Install a jumper between TB1-1 and TB1-9 on PCB A2. This method should be used if a “Safety Circuit” will be
added later in the installation.

3)

De-activate these terminals by moving DIP switch S2-7 to the ON position (toward the enclosure door). This
solution is only suggested if a “Safety Circuit” will never be applied to the drive system.
