If the drive is connected while the motor is hot, the thermal image provided by the Dx2020 GUI
will return a false estimate. This protection supports but doesn't completely replace the
thermal switch in the motor.
In the case of permanent magnet synchronous motor, you can activate the Field
Weakening algorithm, refer to the following information.
Field Weakening Algorithm
This algorithm is available as a "torque increase function" at high speed, allowing increased torque
available above the nominal speed. Obviously, this takes place at the expense of a greater output
current and, consequently, lower yield of the system.
To enable this feature click the "Enable weakening" field. By enabling the "weakening", you can
automatically take advantage of this feature without having to set any parameters. It will prompt you
to select the type of algorithm to use depending on the type of application required; contact
Applications Engineering for assistance.
If controlling an asynchronous motor with IFOC algorithm, the correct Id current and Sg scrolling
values may be required by Applications Engineering, in order to provide the electrical motor
parameters to control.
It is possible to configure the brake through the Brake Motor view. For more information on brake
configuration, refer to the Dx2020 GUI online help, selecting Dx2020 GUI > Views > Configuration
Parameters Motor.
1. From the Navigation Area, select "Feedback": choose the tab "Feedback Sources".
2. Set the timing. Use a current value at or below the rated motor current in order to prevent warm
up of the motor, in case the procedure must be repeated. Later, this value can be increased if
applied to the motor load (Field current timing).
3. Set Time of Phasing according to the application requirements (set to the maximum allowed
value of 4 seconds).
