Changes in C0086 and C0089 overwrite
the setting in C0015
(see chapter ”Commissioning”
→”Operating mode” → ”V/f
characteristic control”)
12. If required, adapt the slip compensation (C0021)
Lenze setting: Rated slip in [%] with regard to N
max
in C0011. The value is calculated from the data of
the nameplate and is thus suitable for the majority
of applications.
Due to changes in C0086, C0087, C0089
the rated slip is recalculated and
automatically entered into C0021
(see chapter ”Commissioning” →”Slip
compensation”)
13. 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
14. Set the operating mode ”V/f” (C0006)
Lenze setting: 5 (V/f characteristic control)
(see chapter ”Commissioning”
→”Operating mode” → ”V/f
