3.6.2.7 Analog output signal
When the device is used with its default settings, there will be an analog
voltage signal (0 - 10 V) available at control signal terminal 8. This value will
correspond to 0 to 100% of P-01 (maximum frequency / speed). The output
can handle a maximum load of 20 mA.
Parameter P-25 is used to configure whether this output signal will be
provided at the terminal:
Table 16: Control signal terminal 8 (AO)
3.6.2.8 Relay contact
Control signal terminals 10 and 11 are connected to the DC1 variable
frequency drive’s internal relay contact (N/O) in a potential-free manner.
The relay function can be configured with parameter P-18:
