INPUTS
CP1/CP2
(count inputs)
Count signal inputs.
Up, Down, and Reversible (command, individual, or phase difference) inputs accepted.
Maximum counting speed: 5 kcps.
Present value reset (to zero in Up or Up/Down modes, to preset with 1-stage models
in Down mode and to preset 2 for 2-stage models in Down mode).
Count inputs are not acknowledged while reset input is ON.
Reset indicator lit while reset input is ON.
Reset, Right Shift and Up keys are inoperative while key protect input is ON.
Although Display key remains effective, only monitoring of settings is possible.
Keys protected indicator lit while key protect input is ON.
Effective when power supply is turned off.

Key protect
Count Input vs. Reset Input
When the RESET input is ON or the RESET key input is ON,
the count input is prohibited and the present value is reset.
However, when the key protect input is ON and the key protect
level is KP-2 or KP-4, no RESET key input is accepted.
Reset Time
Set to 1 ms if high-speed resetting is necessary. Set the reset
time to 20 ms if you need to prevent false signals caused by
electrical noise from affecting the counter.
Outputs 1 and 2
Outputs made according to designated output mode when corresponding preset is
reached.

OUTPUTS
Using Prescale Function
The prescale function converts the number of input counts into
a user-selectable value. The example below shows a system
that uses 250 encoder pulses to determine when an object has
advanced 0.5 meters. Here is how to convert pulses into a unit
of measure appropriate for your application:
1. Set the decimal point between the third and fourth digits.
2. Set a prescale value of 0.002. This is calculated by
dividing the unit of measure (0.5) by the number of pulse
counts (250).
