This parameter displays the level of the analog signal present at analog input 1.
In voltage mode, this is a unipolar voltage input where the input range is 0 to +10V.
In current mode, this is a unipolar current input having a maximum measurable input of 20mA. The drive can be programmed to convert the measured
current to any one of the defined ranges in Pr 7.06. The selected range is converted to 0 to 100.0%, the resolution being 10 bit for the 0 - 20mA range.
Resolution is 0.1%. Accuracy: ± 2%
This parameter display's the level of the analog input 2.
This is a unipolar voltage input having a range of 0 to +10V which is converted to 0 - 100%, the resolution being 10 bits.
Analog input 2 can also be configured as a digital input in which case this parameter will indicate 0 or 100% depending on the state of the input.
Resolution is 0.1%. Accuracy: ± 2%
This parameter displays the temperature currently being measured on the heatsink. If the level reaches 95°C the drive will trip O.ht2 on the display.
This is used as part of the drive's thermal model, see Pr 10.18 on page 131 for further details.
On Commander SK size 2 and 6, this is power pcb temperature;
on Commander SK size 3, this is rectifier temperature;
on Commander SK size 4 and 5, this is rectifier and power pcb temperature.
For drive sizes 2 to 5, two temperatures are available from the power circuit, and these are displayed in Pr 7.04 and Pr 7.05. For drive size 6, three
temperatures are available from the power circuit, and these are displayed in Pr 7.04, Pr 7.05 and Pr 7.36.
If the temperature displayed in Pr 7.04, Pr 7.05 or Pr 7.36 exceeds the trip threshold for the parameter then an O.ht2 trip is initiated. This trip can
only be reset if the parameter that has caused the trip falls below the trip reset level. If the temperature exceeds the alarm level a 'hot' alarm is
displayed. If the temperature for any of these monitoring points is outside the range -20ºC to 120ºC it is assumed that the monitoring thermistor has
failed and a hardware fault trip is initiated (Pr 7.04 causes HF27 trip, Pr 7.05 or Pr 7.36 causes HF28 trip).
