Operating modes set in MDO1 (2,3,4) Digital Output: P270, (P279, P288, P297)
The user can select one of the following operating modes:
Table 40: Digital Output Mode.
DISABLE
The selected digital output is disabled.
DIGITAL
The digital output depends on a selected digital signal and on the logic output
function (True/False).
See Examples 1 and 2.
DOUBLE DIGITAL
The digital output depends on 2 selected digital signals, on the logic function
calculating the output value and on the logic output function (True/False).
ANALOG
The digital output depends on a selected analog variable, which is tested through
Test A and Test B, thus obtaining 2 digital signals; starting from their value, the
selected logic function calculates the output value, whereas the True/False logic
output function calculates the end value.
See Example 3.
DOUBLE ANALOG
The digital outputs depends on 2 selected analog variables: Test A is performed for
variable A, whilst Test B is performed for variable B, thus obtaining 2 digital signals;
starting from their value, the selected logic function calculates the output value,
whereas the logic output function True/False calculates the end value.
DOUBLE FULL
As DOUBLE ANALOG or DOUBLE DIGITAL mode, but both digital signals and
analog variables can be selected.
If you select a digital signal, its value (TRUE or FALSE) is used to calculate the
selected logic function.
If you select an analog variable, the test selected for this variable is performed, and
its result (TRUE or FALSE) is used to calculate the selected logic function.
BRAKE
As ABS BRAKE below, although the selected variables are not expressed as
absolute values, but depend on the selected tests.
ABS BRAKE
The ABS BRAKE mode allows controlling the electromechanical brake of a motor
used for lifting applications. To enable the relevant output, make sure that all the
conditions depending on the drive status are true (see the description at the end of
this section).
The ABS BRAKE mode is applied by selecting the measured (or estimated) speed
value [A71] as the first variable, and the output torque [A80] as the second variable.
Variables are considered as absolute values.
See Example 4.
ABS LIFT
As ABS BRAKE, but the brake unlocks (digital output open) when a given torque
value is attained, which is automatically determined based on the last torque value
required in the previous stroke.
PWM MODE
The PWM mode may be selected for digital outputs MDO1 and MDO2 only (it
cannot be selected for relay digital outputs MDO3 and MDO4).
The digital output becomes a low-frequency PWM output with a duty–cycle
proportional to the value of the selected analog output.
See Example 5.
