X: Compare function settings:
Bit
Function
Explanation
Bit0: When the value of P5-58 is higher than 0, setting Bit0 to 1 will enable the
compare function. Once the compare function is enabled, everytime when one
position is compared, the setting value of P5-58 will decrease 1. When the
setting value of P5-58 is equal to 0, it indicates that the compare operation has
finished and the value of Bit0 will be reset to 0 automatically.
When the value of P5-58 is equal to 0, setting Bit0 to 1 will not enable the
compare function, and then the value of Bit0 will be reset to 0 automatically. If
Bit0 is set to 1 already, the new setting value cannot be 1. The users only can
set Bit0 to 0 to disable the compare function.
Bit1: When Bit1 is set to 1, after the last position is compared, the setting value
of P5-58 will be reset and start the compare operation from the first position
again. The compare operation will not stop and the value of Bit0 will be retained
as 1.
Bit2: When Bit2 is set to 1, after the last position is compared, the system will
enable the capture function (Bit0 of P5-39 is set to 1 and the value of P5-38 is
set to the last capture amount). If the capture function is enabled already, this
setting will become ineffective.
Bit3: When Bit3 is set to 1, after the last position is compared, the counter, i.e.
the setting value of parameter P5-57 will be reset to 0.
For example, when the compare data is set to 3000 pulses (total one compare
data only) and the default value of P5-57 is 0, if the input command is 4000
pulses, the compare operation will stop after the input command reaches 3000
pulses. At this time, P5-57 will be clear to 0. When input command reaches
4000 pulses, the setting value of P5-57 will become 1000 (no accumulated
error).
