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: terminals." Keep in mind that
on the standard LED keypad display, only the number of the choice will be shown. The optional LCD keypad display is
required to see the complete description.
The Safety Interlock Circuit at Power Up
On power up the E7N 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.
