Omron FQM1-CM001 ユーザーズマニュアル

The AXIS instruction is used to generate a virtual pulse output with trapezoi-
dal acceleration/deceleration.

The operands for the AXIS instruction are a target position specified in pulses
or as an absolute position, and a target speed specified in pulses/s (Hz).
While the AXIS instruction’s input condition is ON, it internally generates the
specified number of pulses and integrates (counts) the number of pulses
(area) in the trapezoid.

Sets the output mode.

• #0000: Relative mode

• #0001: Absolute mode

Sets the calculation cycle.

• #0000: 2 ms calculation cycle

• #0001: 1 ms calculation cycle

• #0002: 0.5 ms calculation cycle
