Electrical Life Expectancy
(Reference Values)
Resistive Load
Inductive Load
A current of 0.15 A max. can be switched at 125 VDC (cosφ = 1) and current of 0.1 A max. can be switched with L/R = 7 m/s. In both cases, a life of 100,000 operations can be expected.
I/O Functions
Using as a Counter (See note 1.)
| Inputs | CP1, CP2 | (1) All Modes Except for Dual Counter Mode Reads count signals. Increment, decrement, up/down (command, individual, or quadrature) inputs can be used. (2) Dual Counter Mode Reads CP1 count signals on CP1 input and CP2 count signals on CP2 input. Increment signals can be used. |
| Reset or Reset 1 | (1) All Modes Except for Dual Counter Mode Resets present value and outputs (OUT2 when using the batch counter). (See note 2.) Counting cannot be performed while resetting or when reset 1 input is ON. The reset indicator is lit while the reset input is ON. (2) Dual Counter Mode Resets the CP1 present value to 0. Counting the CP1 input cannot be performed while the reset 1 input is ON. The reset indicator is lit while the reset 1 input is ON. | |
| Total Reset or Reset 2 | The reset operation depends on the selected function. (See note 3.) | |
| Outputs | OUT1, 2 | When the corresponding set value is reached, signals are output according to the designated output mode. |
Note:
1. Refer to Datasheet for information on the operation of input and output functions.
2. In increment mode or increment/decrement mode, the present value returns to 0; in decrement mode, the present value returns to the set value with 1-stage models, and returns to set value 2 with 2-stage models.
3. The reset indicator will not be lit when the total reset or reset 2 input is ON.
| Function | Reset operation |
| 1-stage/2-stage preset counter | Does not operate (Not used). |
| Total and preset counter | Resets the total count value. Holds the total count value at 0 while the total reset input is ON |
| Batch counter | Resets the batch count value and batch output (OUT1). Holds the batch count value at 0 while the reset 2 input is ON. |
| Dual counter | Resets the CP2 present value. Counting for CP2 input is disabled while the reset 2 input is ON. |
Using as a Tachometer
| Inputs | CP1, CP2 | Reads counting signals. (CP2 input is not available.) |
| Reset 1, Reset 2 | Holds the measurement value and outputs. (Reset 2 input is not available.) The reset indicator is lit during hold. | |
| Outputs | OUT1, 2 | Outputs signals according to the specified output mode when a set value is reached. |
Using as a Counter or Tachometer
| Key protection input | Prohibits using the keys on the front panel. Set the key protection level in function selection mode. |
Note: For details, refer to Datasheet.
