Motor Characteristics Listed below are some variable speed AC motor control concepts with which the user of the H9 Adjustable Speed Drive should become familiar. Motor Autotuning Motor production methods may cause minor differences in the motor operation. The negative effects of these differences may be minimized by using the Autotune feature of the H9 ASD. Autotuning is a function of the H9 ASD that measures several parameters of the connected motor and places these readings in a stored tab

Power Factor Correction DO NOT connect a power factor correction capacitor or surge absorber to the output of the H9 ASD. If the ASD is used with a motor that is equipped with a capacitor for power factor correction, remove the capacitor from the motor. Connecting either of these devices to the output of the ASD may cause the ASD to malfunction and trip, or the output device may cause an over-current condition resulting in damage to the device or the ASD. Light Load Conditions When a motor is

Load-produced Negative Torque When the H9 ASD is used with a load that produces negative torque (an overhauling load), the over- voltage or over-current protective functions of the ASD may cause nuisance tripping. To minimize the undesirable effects of negative torque the dynamic braking system may be used. The dynamic braking system converts the regenerated energy into heat that is dissipated using a braking resistor. The braking resistor must be suitably matched to the load. Dynamic braking
