8.2.4 Formula to estimate the start values for "F0" and "t"
Formulas for parameters "F0" and "t" for motor powers that are not listed above are:
I
N motor
kW
motor
x 17 kW
motor
x 12
F0 ≈ 800x
I
N DSV
t
new motor
=
tanφ
motor
+ 20
t
old motor
=
tanφ
motor
+ 20
The above formulas for the rotor time constant are rules of thumb, which are applicable up to approx. 22 kW.
Exact values can be obtained from your motor manufacturer. Value "t" is doubled for 50 MHz systems
(asynchronous-gearless). Using inverters with high-current-resolution (TUDx05N, x06N, x07N), F0 is higher.
8.2.5 Motor characteristics
Motor and equipment design in dependence on the characteristic curve and efficiency
Motor characteristic curves:
Old motor
Characteristic factor =
600
Typical curve for an older
Silumin motor.
New motor
Characteristic factor =
700
Typical curve of a
newer asynchronous motor.
load capacity [in kg] x v
max
[in m/s] x 16As
required maximum current in A =
gear efficiency x characteristic factor x 1kgm x pulley efficiency
pulley efficiency ≈ 1-(number of pulleys × 0,045)
Detailed information related to the electrical design can be found in our "Technical Customer Information"
8.2.6 Optimisation of parameters "F0" and "t"
F0 Rotor flux and t Rotor time constant can be optimised locally by means of trial runs.
To do this, you need a current tong-test instrument, with which you can determine the minimum motor
current. The measurement accuracy is therefore insignificant. The probe should be an "analogue" device.
Presettings, conditions:
• Speed V3 = 50-80 % of the rated speed
• Set the P-gains F7 and k to 400-800 (if possible, to 800)
• Set F0 and t to the start values; see Chapter: "Adjustment of parameters "F0" and "t" dependent upon
the installed motor"
• A run at constant speed over several floors must be possible so that accelerations do not disturb the
current measurement
• Constant load during motorised operation

- Important the parameter t for asynchronous gearless motors under tudzxxn is twice as high as shown in the commissioning table for synchronous gearless motors t is constant and f0 specifies the type of motor because of this you must not change f0 randomly don t change t f0 43

- F0 rotor flux 44
- Page 44 44
- Rotor flux f0 is responsible for the no load current field of an asynchronous motor we recommend the use of the values in the tables and or the project related settings if the flux is too large the motor heats up unnecessarily while if the flux is too small the starting torque is reduced the flux serves the coding of the motor in the case of synchronous motors do not change the setting under any circumstances one sets the maximum necessary current is set with f0 in encoder free mode the values are then normally 4 digit in this case 44
- T rotor time constant 44
- The above named values in the tables for f0 and t apply only to asynchronous motors with gearbox tudyxxn or tudxxxn firmware value t is doubled for tudzxxn firmware using for example asynchronous gearless note tud version is written on dsv typeplate all gearless asynchronous are preset the values can deviate from the above mentioned table only the values set in the factory are valid for synchronous motors they may not be altered since this removes the winch type code in the converter see details also chapter operation of synchronous gearless motors 44
- The rotor time constant t is responsible for the motor torque rotor it is dependent upon the motor cos ϕ if cos ϕ is poor then t is also small if the value of t is too large torque losses occur values that are too small lead to oscillations in the acceleration range use the values in the table and or any preset project values the exact value for the motor specific parameter t can also be obtained from the motor manufacturer attention the double table value must be entered for asynchronous gearless new motor line e g klose 18 kw has t 600 at f0 500 44
