3.1. Operation in the bi-pulse mode



In the bi-pulse mode, the counter counts up/down based on the pulses with 90-degree phase difference in A phase and B phase inputs.

The count starts when the permission condition of the external input gate signal and command signal is met (the count starts from "0").

The counter counts up if A phase is leading, or counts down if B phase is leading.

If the external input gate signal is prohibited and the command is permitted, counting is performed, but the interrupt status does not change. If the command signal itself is prohibited, counting itself stops.

3.1.1. Bi-pulse counter

The bi-pulse counter detects the phases of A phase and B phase to count up/down. Only the count register is used. The interrupt status changes at an overflow (or underflow).

Condition:

EP AL HL DT Parameter setting 1 0 0 0

Pulse input Gate input External

input Two-phase (A, B phase) pulse connection

ON level, or batch permission (GEN = ‘1’)

Operation:

(1) When permission of the command external input condition is met, counting starts to count up/down by detecting the phases of A phase and B phase.

(2) When the command is permitted, count operation is executed. However, if the gate input is prohibited, the interrupt status (upper limit/lower limit) does not change.

(3) The count is reset to "0" when both the command and gate input become ‘1’.

(4) Count operation is not performed as long as the command is prohibited (‘0’) even if the gate input is permitted.

3.1.2. Bi-pulse counter with upper-lower limit alarm

This counter operates similarly as the 3.1.1. Bi-pulse counter. With

upper-lower limit alarm, upper limit and lower limit alarm values can be

specified, and an interrupt status change can be generated every time the

count passes through this value.

The setting value can be set to each of the upper limit alarm register and lower limit alarm register. Overflows and underflows of the counter are ignored.

Condition：





Operation：

(1) For the bi-pulse counter with upper-lower limit alarm, the following 3 registers are assigned to one channel.

Pointer CHx register name Description

n CHx count register Count value

n+4 CHx upper limit alarm register Alarm value during count up

n+8 CHx lower limit alarm register Alarm value during count down

The alarm register is set to 0 when the power is turned on. For other operation, it is continuously updated to the alarm data of the data (received by the PI924 via scan) sent from the controller.

(2) A change in the interrupt status register is prohibited when -32768 (8000h) is set to the upper limit alarm register, or 32767 (7FFFh) is set to the lower limit alarm register. If the alarm value is ‘0’ during gate permission, no initial interrupt occurs.

(3) The upper limit alarm is valid in the count-up direction, and the lower limit alarm is valid in the count-down direction.

(4) The operation for the command and gate input is the same as the bi-pulse counter.

(5) The upper limit status (US) changes when the following register data rewrite occurs. When a change occurs from (Upper limit alarm value > Count value) to (Upper limit alarm value ≤ Count value).

(6) The lower limit status (LS) changes when the following register data rewrite occurs. When a change occurs from (Lower limit alarm value < Count value) to (Lower limit alarm value ≥ Count value).

3.1.3. Bi-pulse counter with hold

This counter operates similarly as the 3.1.1. Bi-pulse counter. With hold, when the command or gate input becomes prohibited, the count value can be transferred to the hold register to be held. The interrupt status changes at an overflow (or underflow).

Condition：





Operation：

(1) For the bi-pulse counter with hold, the following 2 registers are assigned to one channel.



n+4 CHx hold register Count value when the gate prohibition condition occurs

n+8 Not used -

The initial value of the hold register is "0" until the first hold occurs.

(2) The operation for the command and gate input is the same as the bi-pulse counter.

3.1.4. Bi-pulse counter with hold/alarm

This counter operates similarly as the 3.1.1. Bi-pulse counter. With hold/alarm, when the command or gate input becomes prohibited, the count value can be transferred to the hold register to be held.

In addition, one point of alarm value can be specified, and an interrupt status change including count direction can be generated every time the count passes through this value.

Overflows and underflows of the counter are ignored.

Condition:





Operation:

(1) For the bi-pulse counter with hold/alarm, the following 3 registers are assigned to one channel.



n+4 CHx hold register Count value when the gate prohibition condition occurs

n+8 CHx upper-lower limit alarm register

The initial value of the hold register is "0" until the first hold occurs.

(2) For the upper-lower limit alarm value, the upper limit status change is prohibited for -32768 (8000h), and the lower limit status change is prohibited for 32767 (7FFFh).

3.2. Operation in the duty mode

In the duty mode, the counter counts up from 0 when the gate input is ON, or counts down from 0 when it is OFF based on the A phase pulse input or internal reference pulse.

For the B phase pulse input, counting is permitted when it is ON, and prohibited when it is OFF.

For the command, similarly, counting is permitted when it is '1', and prohibited when it is '0'.

The operation above can be applied to pulse width measurement.

If any channel uses this mode, set the gate batch permission setting (GEN) to "Not used" (‘0’), and enable the external gate input.
