This parameter defines the parameter to be represented by the status relay. Only valid parameters can be selected as a source for the relay output. If
a non-valid parameter is programmed, then the relay will remain in the de-energized state.
This parameter selects the function of Terminal B3 as follows:
If modes 1, 2 or 3 are selected, the digital input operation of the terminal is disabled.
In modes 0 and 1, terminal B3 will function as digital input/outputs which are described in menu 8.
In modes 2 and 3, terminal B3 will function as a frequency output or a PWM output as described in menu 3.
The frequency output will be scaled automatically to the source parameter. For example, with a source parameter of Pr 1.21 equal to 100 and an
output frequency of 10kHz (Pr 3.18), when the value of Pr 1.21 is 50, the output frequency will be 5kHz.
Examples
From default, setting Pr 8.31=Fr, will give a 5kHz output with a 50Hz reference value, when Pr 8.21=2.01 (with Pr 8.41=USEr). By setting the scaling
(Pr 3.17) to 0.01, this will give an output of 50 pulses/sec. With a 50Hz reference value.
From default, setting Pr 8.31=PuLS, will give a 24V output with a 50Hz reference value, when Pr 8.21=2.01 (Pr 8.41=USEr). By feeding this PWM
output into a R/C network, a voltage output can be obtained. This output would be almost proportional to the frequency output of the drive.
This parameter selects the function of Terminal B7 as follows:
If modes 1, 2 or 3 are selected, the digital input operation of the input is disabled.
In mode 0, the digital input functions as described in menu 8.
In mode 1, the input functions as a motor thermistor (PTC type).
Trip resistance: 3kΩ
Reset resistance: 1k8
The drive will not trip if the thermistor goes short circuit.
