P9 ASD Installation and Operation Manual

P9 ASD Characteristics
Over-Current Protection
Each
P9 ASD
model is designed for a specified operating power range. The P9 ASD will incur a trip if the
design specifications are exceeded.
However, the P9 ASD may be operated at 100% of the specified output-current range continuously or at
120% for a limited amount of time as indicated in the section titled
Current/Voltage Specifications on pg.
may be adjusted to help with nuisance over-current trips (see
).
When using the P9 ASD for an application to control a motor that is rated significantly less than the
maximum current rating of the P9 ASD, the over-current limit (Thermal Overload Protection) setting will
have to be changed to match the FLA of the motor. For further information on this parameter, see
Overload Protection Level 1 on pg. 194
.
P9 ASD Capacity
The
P9 ASD
must not be used with a motor that has a larger capacity than the ASD, even if the motor is
operated under a small load. A P9 ASD being used in this way will be susceptible to a high-output peak
current which may result in nuisance tripping.
DO NOT
apply a level of input voltage to a P9 ASD that is beyond that which the P9 ASD is rated. The
input voltage may be stepped down when required with the use of a step-down transformer or some other
type of voltage-reduction system.
Using Vector Control
Using
Vector Control
enables the system to produce very high torque over the entire operating range
even at extremely low speeds.
Vector Control
may be used with or without feedback. However, using
feedback increases the speed accuracy for applications requiring precise speed control.
See
for further information on using
Vector Control
