Toshiba PWU001Z-1 Memory protection function prot, －Selecting a desired function －

4.4. Memory protection function “prot”

The memory protection function protects the selected memory so as to prevent it from erroneous replacement of its data with different data copied from another memory.

When this function is actuated for a selected memory, it inhibits transcribing copied data to the memory but permits to read data from the memory.

At the time of shipment or when all the memories are initialized by memory initialization function (clr), LED indications are as follows:

“in”、“a”、“b”、“c=“off”、“sup”=“on”

Operating procedure

Key	LED indication	Key operation and description
	“chc ”→“init”	When the parameter writer is turned on as it is connected with the inverter.
	→“c0py”	“chc” appears on the display first and then “init” appears to indicate that
		the power supply is being initialized. Lastly, the display shows “copy”.
	“c0py”→“comp”	－Selecting a desired function－
SFT	→“pr0t”	Select “prot " (memory protecting function) with the SFT key.
		Each time the SFT key is pressed. indication on the display changes from
△		“copy” (copying function) to “comp” (comparing function),”prot" (memory
		protecting function). “clr” (memory initializing function) and to..”copy” again
		in this order.
	“pr0t”→“in”	－Entering the selected function－
ENT		After selecting “prot " with the SFT key, press the ENT key and “in”
		(selecting inverter memory) appears on the display.
	“in”→“a”→“b”	－Selecting a memory to protect its data－
SFT	→“c”→“sup”	Each time the SFT key is pressed, indication on the display changes from “in”
	→“in”	(selecting inverter memory) to “a” (selecting memory A), “b” (selecting memory
△		B), “c” (selecting memory C), “sup” (special parameter selection*1) and to
		“in” again in this order. Select the memory to protect its data.
	“in”→“off”	－Entering the memory to protect its data－

		When “off” appears on the display, the Selected memory is not protected.)
	“in”)
SFT	“off”→“on”	－Protecting the selected memory－
	→“off”	Each time the SFT key is pressed, indication on the display changes between "
△		on" (protecting the selected memory) and “off” (cancelling protection of the
		selected memory) alternately.
	“on”→“pr0t”	－Executing protection of the selected memory－
ENT		After selecting ''on" (protecting the selected memory, by way of example) with
		the SFT key, press the ENT key. The parameter writer starts protecting the
		selected memory (canceling protection in case of “off”) and indication of the
		display returns to “port”.

・If the ESC key is pressed, the parameter writer returns to the status one before.

(*1) Protecting operation of “sup” is different from that provided for other memories and is shown below.

With the same inverter types (capacities):

sup	Standard	Special
	parameter	parameter
on	○	×
off	○	○

With different inverter types (capacities):

sup	Standard	Special
	parameter	parameter
on	○	×
off	×	×
(Note)

○Protection disabled (write permitted)

×Write protected (write prohibited)

Note: When inverter types (capacities) are different, copying operation of parameters (including special parameters) is prohibited.
