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).

Counter
1 For following
counter modes
• Absolute linear
(CW −)
• Absolute circu-
lar
• Absolute linear
(CW+)
PV of abso-
lute number
of rotations Contains the number of rotations data (PV) read from
the Encoder when the SEN signal is input to the
Servo Driver.

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).
