This setting is available only in the setting mode. However, when the parameter
change in program control function is enabled, this setting can be changed in the
operation mode also. For details on the parameter change in program control
function, refer to Section 3.2.18.
To activate the change, turn on Setting change command (YnB).
(1) Use this area for the following.
To set the set value (SV) at the start of program control when:
• SV start is set in Start mode (buffer memory address: 273, 529).
• PV start 3 (time shortened/find type) is set in Start mode (buffer memory
address: 273, 529), and no point matches the measured value (PV) at the
start of program control is found.
(2) The setting range is within the input range.
Set a value that satisfies the following condition in Upper/lower setting
limiter (buffer memory address: 55, 56, 87, 88):
• Lower setting limiter
Upper setting limiter
The condition above must be also satisfied even if Start mode (buffer memory
address: 273, 529) is set to Zero start, PV start 1 (time fixed), or PV start 2
(time shortened).
If the value set does not satisfy the condition above, a write error occurs. Then
Error flag (Xn2) turns on and the error code 4 is stored to Error code (buffer
memory address: 0).
