Thermal Overload Protection - Veikong gpd 515/g5 Startup Manual

5 . 4 1 T H E R M A L OVERLOAD PROTECTION
E 2 - 0 1 : Motor Rated Current
This parameter should be set according to the rated current value shown on the motor
nameplate; this value must be within 10-120% percent of the drive rated current (refer to
Specifications in Appendices 2 & 3 of this manual).

L 1 - 0 2 : Motor Overload Protection Time
Constant
This parameter sets the electronic thermal overload relay protection time. Actual overload
time can be calculated using the time from the overload characteristics curves then
multiplying that time by L 1 - 0 2 / 8 .
The drive protects against motor overload with a UL-recognized, built-in electronic thermal
overload relay.
The electronic thermal overload function monitors motor temperature, based on drive
output current and time, to protect the motor from overheating. When the electronic
thermal overload relay is enabled, an " O L 1
OFF the drive output and preventing excessive overheating of the motor.
When operating with one drive connected to only one motor, an external thermal relay is
not needed. When operating several motors with one drive, install a thermal overload relay
on each motor.
