Motor overload protection

￭
Motor overload protection is not enabled by default. Motor overload protection can
be measured or estimated in one of the following ways: 1) using motor temperature
devices, 2) using a motor model defined by parameters, or 3) using motor current and
motor class curves. To enable protection using motor temperature devices or motor
model parameters, set parameter 35.11 and subsequent parameters through 35.55.
To adjust motor class curves (default is class 20), change parameters 35.56 and 35.57.
Use the information key (
group 35 parameters. You must set the drive overload parameters correctly, or motor
damage can occur.
Fieldbus communication
￭
To configure the embedded fieldbus communication for Modbus RTU, you must set
at least these parameters:
Parameter Setting
20.01 Ext1 commands Embedded fieldbus
22.11 Speed ref1 source EFB ref1
26.11 Torque ref1 source EFB ref1
28.11 Frequency ref1 EFB ref1
