Specifications of Relative positions: 0000 0000 to 7FFF FFFF hex
number of pulses (2,147,483,647 incrementing and decrementing)
Absolute positions: 8000 0000 to 7FFF FFFF hex
(−2,147,483,648 to 2,147,483,647)
(Ranges of position command values and present values for
pulse output instructions)
Origin searches Motor driver and signal wire modes: 3 modes
Origin search modes: 2 modes
Origin detection methods: 3 methods
Feedback pulse High-speed counter 0 and high-speed counter 1 (fixed)
input ports
Maximum response frequency: 100 kHz
Present value range 32 bits: 8000 000 to 7FFF FFFF hex
for feedback pulses
Error counter range 8000 to 7FFF hex (signed)
Error counter calcu- 4 to 1,020 ms (x4)
lation cycle
(1) If inverter positioning 0 is used, pulse output 0 and PWM0 cannot be
used. If inverter positioning 1 is used, pulse output 1 and PWM1 cannot
be used.
(2) If inverter positioning 1 is used with a CPU Unit with 14 I/O Points, origin
searches cannot be used.
(3) If the continuous output mode is specified (i.e., if the number of pulses is
not specified), be sure to use the high-speed counter (linear mode) so
that it does not overflow.

Target value matching and zone comparisons can be used for high-speed
counters with a feedback pulse input from an encoder even when using
inverter positioning.
Specification
Specification
Two 2-phase counters at 50 kHz and two single-
phase counters at 100 kHz
Differential-phase inputs (x4), up/down pulse
inputs, or pulse plus direction inputs
Linear mode
Note Always set linear mode when using inverter
positioning.

Phase Z signal (reset input) + software reset, or
software reset
Up to 48 target values and interrupt task numbers
can be registered.
Up to 8 sets of upper values, lower values, and
interrupt task numbers can be registered.
