6. Connecting and starting the USB001Z unit
To connect the USB001Z unit to your computer, follow these steps:
1) Turn off the input power to the inverter, and after waiting for at least 15 minutes, make
sure that the charge lamp on the inverter is no longer lit. (Your personal computer can
remain powered on.)
2) Connect a USB cable to the USB port on the USB001Z unit and to a USB port on your
computer.
When connecting the USB001Z unit to your computer for the first time, you have to
install its driver. Refer to Chapter 3.
3) Connect an inverter-unit connection cable (optional) between the communication
connector of the USB001Z and that of the inverter. Refer to the instruction manual of the
inverter for connection to the connection port of the inverter, and choose either RS485
(2-wire type)
side
or LOGIC (common serial) side on the USB001Z. At this time, be careful
not to apply force to the connectors.
RS 485 (2-wire type) side: Connectable to such an RS485 (2-wire type) interface port
as that of the VF-nC3, S15, FS1, AS1, or PS1.
LOGIC side:
Connectable to such a common serial interface port as that
of the VF-nC1, S9, S11, A7, or P7.
* Connect the cable only to either RS485 or LOGIC.
4) Turn on the power to the inverter, and set communication parameters.
* Before disconnecting the USB communication unit, also perform above step 1)
beforehand.
* Avoid connecting the conversion unit to a USB hub or extended USB port (e.g.,
PCMCIA card). Or else the conversion unit may become unstable, depending on the
environment in which it is used.
Do not disconnect the USB cable during communication with the inverter.
Otherwise, damage or malfunction will result.
