Max. regenerative current limit
This parameter determines the regenerative overload current which can be sustained
for max. 60 s on a 10 % duty cycle. After the monitored overload duration the system
switches back to the “rated regenerative current limit”.
The value displayed refers to the load components in the motor rated current and in
the constant flux range therefore corresponds to the torque.
If a parameter should change, the type data module initialises the limit to 150 % if
permitted for the maximum current of the inverter.
If a value below the “rated regenerative current limit” is set for the overload limit, this
is limited to the value of “max. regenerative current limit”.
In the “frequency control” structure the inverter is shut down when the permitted
overload duration is reached.
Adjustment range: 0 ... value which provides the maximum inverter current
As supplied: ca. 100 %
Rated motor current limit
This parameter determines the rated motor load current to which the system returns
after an overload. The value displayed refers to the load components in the motor
rated current and therefore corresponds to the torque in the constant flux range.
If a parameter should change, the type data module initialises the limit to 100 %
provided that this does not exceed the inverter rated current.
Adjustment range: 0 ... value limited by the inverter rated current and
“max. motor current limit”.
As supplied: 100 % (motor rated current)
Rated regenerative current limit
This parameter determines the regenerative rated load current to which the system
returns after an overload. The value displayed refers to the load component in the
motor rated current and so corresponds to the torque in the constant flux range.
If a parameter should change, the type data module initialises the limit to 100 %
provided that the inverter rated current is not exceeded.
Adjustment range: 0 ... value limited by the inverter rated current and
“max. regenerative current limit”.
As supplied: 100 % of motor rated current
Acceleration ramp
This parameter determines the acceleration time of the drive.
This time applies for travelling through a frequency range corresponding to half the
value of the parameter "standard frequency". With the standard parameter settings
this means a frequency range of 50 Hz.
The value applies in both directions.
Adjustment range: 0.01 ... 600 s
As supplied: 2 s
