Inverter Positioning
Section 5-3
Note (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.
High-speed Counter
Specifications for Inverter
Positioning
Note 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.
