A600 00 to 15 High-speed Counter 1 PV Range: 8000 0000 to 7FFF FFFF
Note For a Linear Counter, high-speed counter over-
flows/underflows are checked when the PV is read
(i.e., when Module internal I/O is refreshed).

of rotations
Contains the number of rotations data (PV) read from
the Encoder when the SEN signal is input to the
Servo Driver.
8000 0000 to 7FFF FFFF hex
For following
counter modes
• Linear counter
• Circular
counter
Monitor data • When monitoring counter movements (mode 1),
contains the absolute value of the amount of
change in the PV of the high-speed counter over
the specified sampling time as a 8-digit hexadeci-
mal value (0000 0000 to FFFF FFFF hex).
• When monitoring the counter frequency (mode 2),
contains the frequency of the high-speed counter
calculated from the PV of the high-speed counter
between 0 and 7A120 hex (0 and 500 kHz).

quency is not possible for high-speed counter 2.
