groups of resistors:
E12: Closest standard value is 470 Ω, creating an input of
449.9 Ω and 8.997 V.
E24: Closest standard value is 510 Ω, creating an input of
486.4 Ω and 9.728 V.
E48: Closest standard value is 511 Ω, creating an input of
487.3 Ω and 9.746 V.
E96: Closest standard value is 523 Ω, creating an input of
498.2 Ω and 9.964 V.

Table 3.8 Analog Inputs
When used for voltage, analog inputs are scalable by
parameters for each input.
When used for temperature sensor, analog inputs scaling is
preset to necessary signal level for specified temperature
span.
When analog inputs are used for temperature sensors, it is
possible to read out feedback value in both °C and °F.
When operating with temperature sensors, maximum cable
length to connect sensors is 80 m non-screened/non-
twisted wires.

Real-time clock (RTC) with back-up
The data format of RTC includes year, month, date, hour,
minutes, and weekday.
Accuracy of clock is better than ± 20 ppm at 25 °C.
The built-in lithium back-up battery lasts on average for
minimum 10 years, when the frequency converter is
