11. For protecting the motor, set the current limit
values ”I
max
current” (C0022, C0023)
Guide value ≤ 2-fold rated motor current
Power range 0.37 ... 90 kW:
For dissipating the regenerative energy,
use a brake chopper or feedback
module, if necessary
Power range 110 ... 400 kW:
For dissipating regenerative energy, use
a brake resistor, if necessary
(see chapter ”Commissioning” →
”Motor adjustment” → ”Current limit
values”)
A In motor mode and generator mode (C0022)
B Additional limitation in generator mode (C0023)
Condition: C0023 < C0022
12. If the motor temperature is monitored with a
thermal sensor KTY:
Activate the temperature feedback with C0594
(fault SD6)
Lenze setting: 3 (switched off)
A temperature feedback with KTY has a
positive effect on the vector control,
since the motor data identification
considers the temperature influence in
the motor model.
(see chapter ”Commissioning” →
”Motor adjustment”)
13. Start the motor data identification ”ident run”
(C0148)
(see chapter ”Commissioning”
→”Adjusting the motor”)
A Ensure that the controller inhibit is active

The identification starts:
z The segment  goes off
z ”WRK run” is displayed
z The motor is energised and
”whistles”
z The motor does not rotate
E If after approx. 1 ... 2 min the segment  is active
again, inhibit the controller

The identification is completed. The
following values have been detected
and entered into the codes:
z Inverter error characteristic
(C1753/xx)
z Rotor resistance ”Mot Rr” (C0082)
z Stator resistance ”Mot Rs” (C0084)
z Leakage inductance ”Mot Lss”
(C0085)
z Stator inductance ”Mot Ls” (C0092)
14. Set the operating mode ”vector ctrl” (C0006)
Lenze setting: 5 (V/f characteristic control)
(see chapter ”Commissioning” →
”Operating mode” → ”Vector control”)
15. Set the switching frequency ”fchop” (C0018)
Lenze setting:
Power range 0.37 ... 90 kW: 6 (8/2 kHz sin)
Power range 110 ... 400 kW: 6 (4/2 kHz sin)
See chapter ”Commissioning” →
”Switching frequency of the inverter”
16. Set your type of t he speed feedback system
”Feedback type” (C0025)
Lenze setting: 1 (no f eedback)
See chapter ”Commissioning” →
”Setting of speed feedback”
