Motor parameters
Use this parameter group to adapt the inverter to the motor.

Limits
301
•
Minimum speed
Setting range 0 ... 15 ... 5500 [rpm]
The drive does not operate slower than this speed, even when the set-
point zero is entered.
302
•
Maximum speed
Setting range 0 ... 1500 ... 5500 [rpm]
No setpoint greater than the value set here can be entered. The value
set in n
max
applies to the minimum speed and the maximum speed if you
set n
min
> n
max
.
The following values are allowed to be entered as maximum speeds,
depending on the number of poles, in VFC and VFC & DC BRAK. oper-
ating modes:
•
2-pole: maximum 5500 rpm
•
4-pole: maximum 4000 rpm
•
6-pole: maximum 2600 rpm
•
8-pole: maximum 2000 rpm
Fault 08
Speed monitoring may appear if you enter higher values.
The unit automatically sets the maximum speed to the transition speed if
you perform startup.
303
•
Current limit
Setting range 0 ... 150 [% I
N
]
The internal current limit refers to the apparent current, i.e. the output
current of the inverter. The inverter automatically reduces the current
limit internally in the field weakening range. This means the inverter pro-
vides pull-out protection for the motor.
When a hoisting function is activated, a current limit less than the rated
motor current is ignored.
No.
