The iQpump drive can be programmed to accept a PTC (Positive Temperature Coefficient) Thermistor input for monitoring motor
temperature. By setting parameter H3-09 = “E: Motor Temperature,” and attaching the PTC thermistor per the figure below, the iQpump
drive can react to the increasing motor winding temperature with both an alarm (L1-03) and a fault (L1-04).
