IMPULSE•G+ Mini Advanced Instruction Manual – March 2014

Protection Parameters
The IMPULSE•G+ Mini has the ability to protect both the drive’s hardware and motor by allowing
various means to detect and take corrective action when a condition occurs. These include motor
overload detection, torque detection, and the ability to perform a self-diagnostic check, and then
resume operation after a fault is cleared.

Motor Overload
The IMPULSE•G+ Mini protects against motor overload with a UL-recognized, built-in electronic
thermal overload function, so an external thermal overload relay is not required for single motor
operation.
The electronic thermal overload function estimates motor temperature, based on inverter output
current, frequency and time to protect the motor from overheating. This time is based on a “hot start”
for the motor (see Figure 5-25: “Motor Protection Operation Time”). When the thermal overload
fault is activated, an “OL1” trip occurs, shutting OFF the inverter output and preventing excessive
overheating in the motor. As long as the inverter is powered up, it continues to calculate the motor
temperature.
When operating several motors with one inverter, use the internal thermal protection from the motor
in accordance with NEC 430.126 (c) or install an external thermal overload relay on each motor and
disable the motor overload protection, L01.01 = “00”.
