Memory Protection Function "Prot - Toshiba TOSVERT VF Series Instruction Manual

4.3.4. Memory protection function "prot"

The memory protection function protects the selected memory from being overwritten.
When this function is initiated copying data to the memory is prohibited. Reading the memory data is
permitted.
When all the memories are initialized by memory initialization function (clr), the LED indications
are as follows:
"in", "a", "b", "c" = "off", "sup" = "on"
This is also the default setting at the time of shipment.

< Selecting a desired function >
Select "prot" (memory protection function) with the [SFT] key.
< Entering the selected function >
After selecting "prot" with the [SFT] key, press the [ENT] key and "in"
(selecting inverter memory) appears in the display window.
< Selecting a memory to protect its data >
Each time the [SFT] key is pressed, the display changes as follow

< Entering the memory to protect its data >
After selecting "in" (selecting inverter memory, by way of example) with the
[SFT] key, press the [ENT] key and the display shows the present memory
protection status. (When "on" appears on the display, the selected memory
is protected. When "off" appears on the display, the selected memory is
not protected.)
< Protecting the selected memory >
Each time the [SFT] key is pressed, the indication in the display changes
"on" protecting the selected memory (write prohibited)
"off" canceling protection of the selected memory (write permitted)
alternately.
< Executing protection of the selected memory >
After selecting "on" (protecting the selected memory, by way of example) with
the [SFT]key, press the [ENT]key. Remote Keypad starts protecting the
selected memory (canceling the protection in case of "off") and the
indication in the display window returns to "prot".
