3.5.10 Preset Value Writing for Current Position Preset Input
The preset value used for current position preset function by buffer memory format or sequence
format is written. This can be written at any time by the sequence program, but the setting applies
only when external input is accepted for the current position preset by buffer memory format. Two
external inputs are available; one for current position preset input 1 and the other for current position
preset input 2.
(1) The setting value is written as scaling binary. The setting value is written as scaling binary.
(2) The setting range is from [minimum current position value+ scale length -1]. Wtiting to value
out of the range will cause an error 50.
(3) The preset value for current position preset input 1 is used for the current position preset by
sequence format.
(4) The default setting of ‘0’ is establishes at power on.
3.5.11 Current Position Preset ‘Input Disabled’ Setting (Writing)
The settings made at this area determine whether or not current position preset by external input is to
occur. Although this area can be written to at any time by the sequence program, the settings are
operative when an online status or Test mode is established.
(1) Setting are made by designating '0' or '1' for the bits which correspond to the input signal:
0: Current position preset input enabled
1: Current position preset input disabled
(2) As shown below, only the lower two bits are active.
(3) When the power is turned ON, or when the following actions occur, the default setting value '0'
(current position preset input enabled) will be designated at both bits.
