The Model 1000 Series drives are designed to operate on power line frequencies from 48 to 62 hertz.
The
tolerance
of the input voltage is +10% to -10% of the nominal voltage listed on the nameplate. A service that
supplies AC motors, in addition to the drive, must be capable of supporting the starting current of the motors without dropping
more than 10%. If the drive is operating at a line voltage of less than 95% of the nominal line voltage, brief power line
disturbances may trip the drive.
Do not measure the input voltage while the drive is not running. This neglects the effects of load on the power source.
Measure the actual input line voltage while the control is operating the motor in a loaded condition.
Brief power line disturbances will not normally disturb the Model 1000 series drives. The Model 1000 series drives do not
generate significant noise back onto the power service. Events that distort the AC waveform may lower the bus voltage. These
may trigger an under-voltage or power loss condition.
One of the most frequent problems encountered with digital type equipment is electrical noise. Noise is a treacherous
problem that is capable of causing destructive results. It can also cause intermittent and annoying problems. The methods
used in the installation of the equipment plays a large part in prevention of electrical noise interference in operation. Any digital
type control requires that extra care be taken in installation. Pay attention to the grounding of the equipment, the shielding of
wires and cables, and the placement of wires in the conduit runs. Pay attention to the sections of this manual that address the
precautions against noise. This also applies to peripheral equipment.
When you use other manufacturer’s equipment in a system, follow their directions regarding noise suppression and
protection. Pay particular attention to power and grounding requirements.
