Disable the electronic overload protection (L1-01 = 0: Disabled) and wire each
motor with its own motor thermal overload when connecting the drive to more than
one motor for simultaneous operation.
Enable the motor overload protection (L1-01 = “1”, “2”, or “3”) when connecting
the drive to a single motor unless there is another means of preventing motor
thermal overload. The electronic thermal overload function causes an OL1 fault,
which shuts off the output of the drive and prevents additional overheating of the
motor. The motor temperature is continually calculated as long as the drive is
powered up.
Setting L1-01 = 1 selects a motor with limited cooling capability below rated (base)
speed when running at 100% load. The OL1 function derates the motor when it is
running below base speed.
Setting L1-01 = 2 selects a motor capable of cooling itself over a 10:1 speed range
when running at 100% load. The OL1 function derates the motor when it is running
at 1/10 or less of its rated speed.
Setting L1-01 = 3 selects a motor capable of cooling itself at any speed —
including zero speed — when running at 100% load. The OL1 function does not
derate the motor at any speed.
Setting L1-01 = 4 selects protection for a PM motor.
