Yaskawa E7L Drive Bypass - Manual (Page 21)

Physical Installation 1 - 9
Option U
Enable Embedded Serial Communications: A no cost option. The Drive in a Bypass unit is capable of network communications
via one of 3 embedded protocols. Specifying option U will enable the Siemens APOGEE protocol and provide the necessary
parameter settings and wiring (jumpers) to be network ready when delivered (Project specific H5-0X parameters are setup by
the user).
Option V
Enable Embedded Serial Communications: A no cost option. The Drive in a Bypass unit is capable of network communications
via one of 3 embedded protocols. Specifying option U will enable the Modbus protocol and provide the necessary parameter
settings and wiring (jumpers) to be network ready when delivered (Project specific H5-0X parameters are setup by the user).
Option W
Engraved Plastic Nameplate: An enclosure identification nameplate to carry the controlled equipment “tag number”.
Option X
3% DC Bus Reactor: Attenuates harmonic distortion by limiting the rate of rise of the input current. The bus reactor is wired
to the Drive (+1) and (+2) DC bus terminals to provide the equivalent impedance of a 3% input reactor. This option is only
used on the low end of the horsepower range where DC bus reactors are not a standard Drive component (25 HP and below @
208 VAC, 25 HP and below @ 240 VAC, and 30 HP and below @ 480 VAC.)
Option Y
LCD Keypad: Offers 5 lines of display with 16 characters on each line for expanded data presentation capability in English (or
other language) format.
Option Z
5% DC Bus Reactor: Attenuates harmonic distortion by limiting the rate of rise of the input current. The bus reactor is wired
to the Drive (+1) and (+2) DC bus terminals to provide the equivalent impedance of a 5% input reactor. This option is only
used on the low end of the horsepower range where DC bus reactors are not a standard Drive component (25 HP and below @
208 VAC, 25 HP and below @ 240 VAC, and 30 HP and below @ 480 VAC.)
