Setting Motor Protection Operation Time - YASKAWA FSDrive-MV1S Instructions Manual

Multi-Function Outputs (H2-01 to H2-08)
Setting
Value
1F Motor overload (OL1)
Setting Motor Rated Current
Set the rated current value on the motor nameplate in constants E2-01. This set value is the electronic thermal
base current.

Setting Motor Protection Operation Time

Set the motor overload detection start level for L1-06, the motor overload detection level for L1-07, and the
motor protection operation time as for motor overload detection level for L1-02. In these cases, the motor
rated current is set to 100%.
The factory setting is resistance to 150% for 60 seconds.
If the output current exceeds the motor overload detection start level, the electronic thermal protection will
activate.
The following diagram shows an example of the characteristics of the electronic thermal protection operation
time (L1-02=60 seconds, L1-06=110%, L1-07=150%).

Setting Precautions
To detect overloads promptly, keep the set value in L1-02 or L1-07 at a low setting.
•
If L1-06 (motor overload detection start level) is set to be equal or higher than L1-07 (motor overload
•
detection level), an OPE11 (constant setting error) operation error may occur. Set L1-06 to be lower than
L1-07.
