AFP7HSC2T
2-ch type
Linear counter, Ring counter
Signed 32-bit (-2,147,483,648 to +2,147,483,647)
4MHz/8MHz for individual input (phases A and B) (Duty ratio 50±10%)
4MHz/8MHz for direction detection input (Duty ratio 50%±10%)
4MHz/8MHz for 2-phase input (Duty ratio 50±10%, Phase shifting below 5%)
Phases A, B and Z
- Control signal input: 4 points (2
points/ch)
- External output: 4 points (2 points/ch)
- 2-phase input (Phase difference input) 1 multiple, 2 multiple, 4 multiple
- Individual input 1 multiple, 2 multiple
- Direction detection input 1 multiple, 2 multiple
Count operation can be controlled by input signals in combination with three functions.
- Counter enable function (Control signal/Output Y relay)
- Preset function (Input Z signal/Output Y relay)
- Preset function (Input Z signal/Output Y relay)
Only for control signals, the enable function and reset function or preset function can
be combined. The count operation is set by selecting from the following operations.
- Reset operation at rising edge
- Reset operation at trailing edge
- Positive logic reset operation
- Negative logic reset operation
- Preset operation at rising edge
- Preset operation at trailing edge
- Positive logic preset operation
- Negative logic preset operation
- Positive logic enable operation
- Negative logic enable operation
- Positive logic enable operation and reset operation at rising edge
- Negative logic enable operation and reset operation at trailing edge
- Positive logic enable operation and preset operation at rising edge
- Negative logic enable operation and preset operation at trailing edge
Measures the intervals between the changes in the count value, and calculates the
frequency.
Measures the intervals between the changes in the count value, and automatically
calculates the rotation speed.
Measures the time for the number of counts equivalent to one rotation. Sets the time to
reach the specified number of pulses per one rotation, and calcualtes the rotation
speed from the time required for one rotation.
