Precautions
If the set value for the number of pulses per rotation is set to less than the lower limit value or more than the upper limit value,
the number of pulses per rotation operates at the lower limit value or the upper limit value. However, the set value is stored as
is.
High-speed comparison table (high-speed compare instruction) error occurrence error
code
This device stores the high-speed comparison table, high-speed comparison instruction error.
■Corresponding devices
The device numbers corresponding to each channel are as follows.
CPU module
CH1 CH2 CH3
SD4982
■Description
This device stores the error code when an error occurs in the high-speed comparison table, high-speed comparison
instruction.
These devices also operate when the FX3 compatible high-speed counter function is valid.
■Clear timing
The timing when the device is cleared is as follows.
• Power ON, Reset, SM50 turned ON
■Error code
High-speed comparison table maximum excess error: 3780H
Multi-point output high-speed comparison table comparison number
This device stores the number of the table currently being compared in the multi-point output high-speed comparison tables.
■Corresponding devices
The device number is shared for all channels of the CPU module.
CH1 CH2
SD5000
■Description
This device stores the number of the table currently being compared in the multi-point output high-speed comparison tables. If
0, the multi-point output high-speed comparison tables have stopped.
• When rewriting the comparison value or output data for the multi-point output high-speed comparison
tables, the table numbers from the table numbers that follow after the next table number of the table being
compared can be rewritten.
• The table number being compared and the next table number after that can be rewritten, but they will not be
compared.
• These devices also operate when the FX3 compatible high-speed counter function is valid.
■Clear timing
The timing when the device is cleared is as follows.
• Power ON, Reset, STOPRUN
