Details
Counter range: 8000 0000 to 7FFF
FFFF Hex (8 digits hexadecimal)
Note: In Linear Counter Mode,
high-speed counter PVs are
checked for overflow and under-
flow errors when the PVs are read
(at internal I/O refresh for the Cus-
tomizable Counter Unit).
Multi-turn data (PV read from
encoder) input to the counter unit
is stored here when SEN signal is
input to servo driver.
8000 0000 to 7FFF FFFF Hex
(8-digit hexadecimal)
• When monitoring (measurement
mode 1) the rate-of-change of
high-speed counter, the rate-of-
change of high-speed counter
PV within the set sampling time
is stored with 8-digit hexadeci-
mal.
0000 0000 to 7FFF FFFF Hex
• When monitoring (measurement
mode 2) high-speed counter fre-
quency, the frequency is calcu-
lated based on the PV of high-
speed counter for measuring fre-
quency and the result is stored
here with 8-digit BCD.
0000 0000 to 0020 0000 (BCD):
0 to 200,000 Hz
The same as for high-speed
counter 1. (The high-speed
counter frequency is not stored. for
high-speed counter 1.)
0: No error
1: Error occurred
0: Not reading or reading
1: Reading completed (This is set
at the completion of receiving
serial data on No. of rotations.)
