MM-400A
8. Operation Screens
8-93
ABSOLUTE4: The position of 0 mm is set in advance and the displacement is
measured.
In “DIST PULSE1”, “DIST PULSE2”, and “DIST FINAL”, the moving amount
from the position set to 0 mm at the start of current or the external input signal
“DIST TRIGGER” is measured.
In “DIST INITIAL”, the moving amount from the position set to 0 mm set in
advance is measured.
The displacement level 1 to 3 outputs “DIST LEV1 to 3” are output when
moving close to the position set to 0 mm set in advance is output.
In the level output, signals are output when “measured value ≤ level output
value” is satisfied in plus (+) setting and “measured value ≥ level output value”
is satisfied in minus (-) setting.
By applying force without setting workpieces, perform a reset with a reference
position (0 mm).
When using a Mitutoyo’s, HEIDENHAIN’s, or Ono Sokki’s displacement sensor,
the displacement position cannot be held with the power supply of the
MM-400A turned off. Reset displacement after turning on the power supply of
the MM-400A.
When setting TRIGGER to “CURRENT”, INITIAL MEASUREMENT to
“CURRENT START”, MEAS AFTER PULSE to “CURRENT START”, and
FINAL MEASUREMENT to “DELAY TIME” to measure “DIST INITIAL”, “DIST
PULSE1” and “DIST FINAL.”
• Measures the moving amount from the position set to 0 mm in advance as
“DIST INITIAL” (B) at the timing of WE1 current start (A).
• Measures the moving amount from the position of the current start (A) as
“DIST PULSE1” (D) at the timing of WE2 current start (C).
• Measures the moving amount from the position of the current start (A) as
“DIST FINAL” (F) at the timing of the elapse of the delay time (E).
For the trigger, refer to Chapter 8, “l-1. BASIC SETUP (1) Screen.”
