Description of Function

■ Zero blanking (timer)
PV is displayed with zero blanking for the highest unit.
• E.g.) When time range is 99m59.99s and PV is 00m04.05s.
Display value: 0:04.05
■ Start Point (counter)
This function is that start at initial value set at Start Point value.
• When reset is applied, the present value is initialized to Start Point value.
• After Count Up at output operation mode: C, R, P, Q, present value starts at Start Point value.
• If you change the start point value and return to RUN mode, the present value is changed to
the start point value.
• If the Start Point value is changed in the function setting mode, the present value is reset.
• Start Point value setting range is linked to C1-8 Counting value / preset value decimal point
position.
■ Prescale (counter)
This function is to set and display calculated unit for actual length, liquid, position, etc. It is
called 'prescale value' for measured length, liquid, or position, etc per 1 pulse.
• When moving L, the desired length to be measured, and P, the number of pulses per 1
revolution of a rotary encoder, occurs, prescale value is L/P.
• Application
Diameter of pulley connected with encoder is 22 mm, the number of pulses by 1 rotation of
encoder is 1,000

• Select decimal point: -----.-, prescale decimal point: ---.--- and set prescale value: 0.069,
it is available to control conveyor position by 0.1 mm unit.
