A2.4 Integrator
When addition is complete, its result will be passed to the integrator.
An integration method consists of combinations of a reset method and counting up/down. There
are the following seven integration types, which can be set using INTEG_TYPE.
1. UP_AUTO: 0 to TOTAL_SP - auto reset at TOTAL_SP; Integrates from 0 to the
setpoint (TOTAL_SP), and automatically resets when reaching the setpoint.
2. UP_DEM:
reset on demand.
3. DN_AUTO: TOTAL_SP to 0 - auto reset at TOTAL_SP; Integrates from 0 to the
setpoint, and automatically reset when reaching zero.
4. DN_DEM:
reset on demand.
5. PERIODIC: 0 to ? - periodic reset; Integrates from 0, and reset periodically in
accordance with CLOCK_PER.
6. DEMAND:
7. PER&DEM: 0 to ? - periodic & demand reset; Integrates from 0, and is reset
periodically or on demand.
Each type of integration works independently as a function.
There are the following three types of integrated values:
1. Total ............. Integrates the result of the adder as is.
2. ATotal ........... Integrates the absolute value of the result of the adder.
3. RTotal........... Integrates the absolute value of the result of the adder only if the status
The table shows the details of INTEG_TYPE.
