Functions for Servo Drivers Compatible with Absolute Encoders Section 7-7
Auxiliary Area
Pulse input Counter 1 Max. circular
value When the counter operation is set to circular counter,
this parameter sets the maximum value in the circu-
lar counter.
Setting range: 0000 0001 to FFFF FFFF hex
At power ON
Absolute
encoder resolu-
tion
(Number of input
pulses per
encoder revolu-
tion)
0000 0001 to 0000 FFFF hex
Note Set the resolution considering the Servo
Driver's encoder dividing rate and the Motion
Control Module's pulse input multiplier setting.
Example:
Set the resolution to FA0 (4,000) when the Servo
Driver’s rate is 1,000 and the Motion Control Mod-
ule’s multiplier is
×4.
Counter 2 Max. circular
value The counter 2 parameters have the same functions
as the parameters for counter 1, above.
Absolute
encoder resolu-
tion
(Number of input
pulses per
encoder revolu-
tion)
Counter 1 Absolute offset Setting range: 8000 0000 to 7FFF FFFF hex
This is the origin of the application when using an
absolute encoder.
Always
Counter 2 Absolute offset The counter 2 offset has the same function as the
counter 1 offset, above.

A600 00 to 15 High-speed Counter 1 PV 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 underflow errors when the PVs are
read (at built-in I/O refresh for the Mod-
ule).
