Omron SYSDRIVE 3G3MV Setup Manual

• This parameter is used to set the electric thermal characteristics of the motor to be connected.
• Set the parameter according to the motor.
• If a single Inverter is connected to more than one motor, set the parameter to 2 for no protection. The
parameter is also disabled by setting n036 for rated motor current to 0.0. Provide thermal relays or
other methods separately for each motor to protect equipment from overloads.

D Set Values
• This parameter is used to set the electronic thermal protection constant of motor overload detection
OL1.
• The default setting does not need any changes in normal operation.
• To set the parameter according to the characteristics of the motor, confirm the thermal time constant
with the motor manufacturer and set the parameter with some margin. In other words, set the value a
little shorter than the thermal time constant.
• To detect motor overloading more quickly, reduce the set value, provided that it does not cause any
application problems.
