SK CU4-IOE or
SK TU4-IOE Analog functions (max. load: 5mA analog):
An analog (0 ...+10 Volt) voltage can be obtained from the control terminals (max. 5mA).
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.:

100%
P419 value nominal Motor
10Volt


For standardisation of actual values: See also (Section 9.10).
0 = No function, no output signal at the terminals.
1 = Actual frequency*, the analog voltage is proportional to the FI output frequency.
(100%=(P201))
2 = Actual speed*, this is the synchronous speed calculated by the FI based on the existing
setpoint. Load-dependent speed fluctuations are not taken into account.
If Servo mode is being used, the measured speed will be output via this function.
(100%=(P202))
3 = Current*, the effective value of the output current supplied by the FI. (100%=(P203))
4 = Torque current*, displays the motor load torque calculated by the FI. (100% = (P112))
5 = Voltage*, the output voltage supplied by the FI. (100%=(P204))
6 = Link voltage, "Link circuit voltage", is the DC voltage in the FI. This is not based on the
nominal motor data. 10V Volt, standardised at 100%, is equivalent to 450V DC (230V
mains) or 850 Volt DC (480V mains)!
7 = Value of P542, the analog output can be set using parameter P542 independently of the
actual operating status of the FI. For example, with Bus switching (parameter
command) this function can supply an analog value from the FI, which is triggered by
the control unit.
8 = Apparent power*, the actual apparent power calculated by the FI.
(10 0%=(P203)*(P204) respectively = (P203)*(P204)*√3)
9 = Real power *, the actual effective power calculated by the FI.
(100%=(P203)*(P204)*(P206) respectively = (P203)*(P204)*(P206)*√3)
10 = Torque [%]: the actual torque calculated by the FI (100%=Nominal motor torque).
11 = Field [%]*, the actual field in the motor calculated by the FI.
12 = Actual frequency ±*, the analog voltage is proportional to the output frequency of the FI,
whereby the zero point is shifted to 5V. For rotation to the right, values between 5V and
10V are output, and for rotation to the left values between 5V and 0V.
13 = Speed ±*, "Actual motor speed", is the synchronic speed calculated by the FI, based on
the current setpoint, where the null point is shifted to 5V. For clockwise directions of
rotation, values from 5 - 10V are output. For anticlockwise rotation, values from 5V - 0V.
If servo mode is used, the measured speed is output via this function.
14 = Torque [%] ±*, is the actual torque calculated by the FI, whereby the zero point is shifted
to 5V. For drive torques, values between 5V and 10V are output, and for generator
torque, values between 5V and 0V.
30 = Set freq befor ramp, "Setpoint frequency before frequency ramp", displays the
frequency produced by any upstream controllers (ISD, PID, etc.). This is then the
setpoint frequency for the power stage after it has been adjusted by the acceleration or
braking ramp (P102, P103).
31 = Output via BUS PZD, the analog output is controlled via a bus system. The process
data is directly transferred (P546, P547, P548).
32 = Setpoint freq. Motor poti., "Setpoint frequency of motor potentiometer"
*) Values based on the motor data (P201…), or which are calculated from this.
