Safety

WARNING

HIGH VOLTAGE!

Frequency converters contain high voltage when

connected to AC mains input power. Installation, start up,

and maintenance should be performed by qualified

personnel only. Failure to perform installation, start up, and

maintenance by qualified personnel could result in death

or serious injury.

High Voltage

Frequency converters are connected to hazardous mains

voltages. Extreme care should be taken to protect against

shock. Only trained personnel familiar with electronic

equipment should install, start, or maintain this equipment.

WARNING

UNINTENDED START!

When the frequency converter is connected to AC mains,

the motor may start at any time. The frequency converter,

motor, and any driven equipment must be in operational

readiness. Failure to be in operational readiness when the

frequency converter is connected to AC mains could result

in death, serious injury, equipment, or property damage.

Unintended Start

When the frequency converter is connected to the AC

mains, the motor may be started by means of an external

switch, a serial bus command, an input reference signal, or

a cleared fault condition. Use appropriate cautions to

guard against an unintended start.

WARNING

DISCHARGE TIME!

Frequency converters contain DC-link capacitors that can

remain charged even when the frequency converter is not

powered. To avoid electrical hazards, disconnect AC mains,

any permanent magnet type motors, and any remote DC-

link power supplies, including battery backups, UPS and

DC-link connections to other frequency converters. Wait for

the capacitors to fully discharge before performing any

service or repair work. The amount of wait time is listed in

the Discharge Time table. Failure to wait the specified time

after power has been removed before doing service or

repair could result in death or serious injury.

NOTE

Imposed limitations on the output frequency

(due to export control regulations):

From software version 6.72 the output frequency of the

frequency converter is limited to 590 Hz. Software versions

6x.xx also limit the maximum output frequency to 590 Hz,

but these versions cannot be flashed, i.e. neither

downgraded nor upgraded.

1.4 Product Overview

A frequency converter is an electronic motor controller

that converts AC mains input into a variable AC waveform

output. The frequency and voltage of the output are

regulated to control the motor speed or torque. The

frequency converter can vary the speed of the motor in

response to system feedback, such as position sensors on a

conveyor belt. The frequency converter can also regulate

the motor by responding to remote commands from

external controllers.

In addition, the frequency converter monitors the system

and motor status, issues warnings or alarms for fault

conditions, starts and stops the motor, optimizes energy

efficiency, and offers many more control, monitoring, and

efficiency functions. Operation and monitoring functions

are available as status indications to an outside control

system or serial communication network.

1.5 Internal Controller Functions

Illustration 1.3 is a block diagram of the frequency

converter's internal components. See Table 1.2 for their

functions.
