TR200 Programming Guide
Function:
Controls the current limit control integration time. Setting it to a lower
value makes it react faster. A setting too low leads to control instability.
Function:
Torque Characteristics, is set for either
[3].
Function:
Enter the level of motor magnetization at low speed. Selection of a low
value reduces energy loss in the motor, but also reduces load capability.
This parameter cannot be adjusted while the motor is running.
Function:
Enter the minimum allowable magnetization for AEO. Selection of a low
value reduces energy loss in the motor, but can also reduce resistance
to sudden load changes.
Function:
Enter the minimum frequency at which the Automatic Energy Optimiza-
tion (AEO) is to be active.
Function:
The cos(phi) setpoint is automatically set for optimum AEO performance
during AMA. This parameter should normally not be altered. However,
in some situations it may be necessary to enter a new value to fine tune.
