3.4 Buffer Memory Assignment 3.4.2 Details of the buffer memory
(15)CH1 Phase Z setting (Un\G1000)
• Use this memory to set the trigger condition to replace a count value with the preset value using the phase Z
input terminal (Z1).
• Set whether to turn on CH1 External preset/replace (Z Phase) request detection (X05) when replacing a
count value by the phase Z input terminal (Z1).
• When Z phase (Preset) trigger setting is ON, External preset/replace (Z Phase) request detection setting is
disabled and CH1 External preset/replace (Z Phase) request detection (X05) remains off.
• The setting values are enabled by turning off and on Operating condition settings batch-change command
(Y01).
• The default values for External preset/replace (phase Z) request detection setting and Phase Z (preset/
replace) trigger setting are 0: The signal turns on when the preset/replace function is performed and 0: Rise
respectively.
(16)CH1 Periodic interrupt setting (Un\G1001)
• Use this memory to select whether the periodic interrupt function is executed or not and set the values of
either 1
H
: Interrupt or 0
H
: Not interrupt.
• For details on corresponding interrupt factors, refer to the following:
Page 139, Section 4.9.1
• Assign the interrupt factors to interrupt pointers in the CPU module before executing the periodic interrupt
function. Failure to do so may cause an error in the CPU module.
• The setting values are enabled by turning off and on Operating condition settings batch-change command
(Y01).
• The default value is 0
H
: Not interrupt.
(17)CH1 Ring counter lower limit value (Un\G1010, Un\G1011)
• Use these memories to set the lower limit value of the count range when the ring counter is selected for a
counter format.
• Set the upper limit value of the ring counter as well.
• The setting range is between -2147483648 and 2147483647 in 32-bit signed binary format.
• The setting values are enabled by turning off and on Operating condition settings batch-change command
(Y01) or CH1 Count enable command (Y06).
• The default value is 0.
