Memory Protection Function "Prot - Toshiba RKP002Z 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.

After selecting "prot" with the [SFT] key, press the [ENT] key and
"in" (selecting inverter memory) appears in the display window.

with the [SFT] key, press the [ENT] key and the display shows the
present memory protection status. (When "on" appears on the

< Executing protection of the selected memory >
After selecting "on" (protecting the selected memory, by way of
