In the analog output function an offset can be entered to simplify the processing of the analog
signal in other equipment.
If the analog output has been programmed with a digital function, then the difference between the
switch-on point and the switch-off point can be set in this parameter (hysteresis).

Analog functions (max. load: 5 mA analog, 20 mA digital):
An analog (0 ... +10V) voltage can be obtained from the control terminals (max. 5 mA). Various
functions are available, whereby:
0 Volt analog voltage always corresponds to 0 % of the selected value.
10 V always corresponds to the motor nominal values (unless otherwise stated) multiplied by the
P419 standardisation factor, e.g.:

NOTE: Use of module SK CU4-IOE2
: The function of the first analogue output is set as
usual via Array [-
02]. The function of the 2nd analogue output is set via the array
[-03].
Therefore, with the use of an IO extension of this type, only one IO extension can be
evaluated by the frequency inverter.

Function
Description
00
No function
No output signal at terminals.
01
Actual frequency The analog voltage is proportional to the output frequency of the device
02
Actual speed
Is the synchronous speed calculated by the device, based on the present setpoint value. Load-
dependent speed fluctuations are not taken into account. If Servo mode is being used, the
measured speed will be output via this function.
03
Current
Is the effective value of the output current delivered by the device.
04
Torque current
Indicates the motor load torque calculated by the device. (100 % = P112)
05
Voltage
Is the output voltage delivered by the device.
06
DC link voltage
Is the DC voltage in the device. This is not based on the motor rated data. 10 V Volt, standardised
at 100 %, is equivalent to 450V DC (230 V mains) or 850 Volt DC (480 V mains)!
07
Value of P542
The analog output can be set with parameter P542, regardless of the actual operating status of the
device. With bus control, e.g. an analog value from the control unit can be tunnelled directly to the
analog output of the FI.
