When connecting the drive to more than one motor for simultaneous operation, disable the electronic overload protection
(L1-01 = 0) and wire each motor with its own motor thermal overload relay.
Enable the motor overload protection (L1-01 = 1 to 3, 5) when connecting the drive to a single motor, unless another
motor overload preventing device is installed. The drive 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 while the drive is powered up.
