4-83 Power Limit Generator Mode

Range: Function:
100.0 % [0.0 - Enter the maximum generating power
*
200.0 %] when the power limit function is active.
Related parameters: parameter 1-20 Motor
Power [kW], parameter 1-21 Motor Power
[HP].

3.5.8 4-9* Directional Limits

The directional limits functionality allows to specify
different torque and speed limits for different
combinations of torque application direction and rotation
direction. For example, see Illustration 3.34. In the
illustration, quadrants 1–4 show different combinations of
rotation direction and torque application direction, and the
parameters that act in different quadrants.

Illustration 3.34 Directional Limits
A speed limit value cannot exceed the value of
parameter 4-13 Motor Speed High Limit [RPM] or
parameter 4-14 Motor Speed High Limit [Hz]. A torque limit
value cannot exceed the value of parameter 4-16 Torque
Limit Motor Mode or parameter 4-17 Torque Limit Generator
Mode.

4-90 Directional Limit Mode

Select whether the directional limits are enabled. With directional
limits enabled, it is possible to specify different speed and torque
limits for clockwise and counterclockwise rotation directions.
