*1. As set in the communication parameters n8 "operation command write" and n9 "speed command write". (refer to page 130)

*2. At occurrence of RS-485 communication error, the inverter cannot be reset from the computer.

*3. As set in Pr. 75 "reset selection/PU stop selection".

*4. As set in Pr. 77 "parameter write disable selection".


	CAUTION	2


* When the user program of the computer is used to make the running frequency
setting by RS-485 communication, setting can be made in the minimum setting
increments of 0.01Hz, but the setting may be written to the inverter in increments
of 0.1Hz. (0 is written in the second decimal place.)


	POINT


To make RS-485 communication between the inverter and personal computer, the
operation mode must be set to the "computer link operation mode".
Pr. 79 "operation mode selection" ≠ ‚ "1, 3, 4"
and communication parameter n10 "link start mode selection" = "1"
Reset the inverter after setting the communication parameters n1, n2, n3, n4, n7,
n11. The values set are registered once the inverter is reset.
