6.3.3 Analog outputs

The analog outputs primarily help display status variables such as output frequency,

motor voltage, or present motor current within the scaleable range.

r0770

Shows the number of available analog outputs.

P0771

Defines the physical status variable to be displayed as an analog signal.

Possible settings:

21 Present output frequency (scaled to P2000), (factory setting).

24 Present VSD output frequency (scaled to P2000).

25 Present output voltage (scaled to P2001).

26 Present link voltage (scaled to P2001).

27 Present output current (scaled to P2002).

Index:

P0771[0]: Analog output 1 (DAC 1).

P0771[1]: Analog output 2 (DAC 2).

P0773

This parameter enables smoothing for the DAC input with a

PT1 filter and determines the smoothing time in ms for the

analog output signals.

Setting range: 0 to 1000 ms

Recommended setting: 100 ms (factory setting)

Index:

P0773[0]: Analog output 1 (DAC 1).

P0773[1]: Analog output 2 (DAC 2).

Note: The filter is disabled for P0773 = 0.
