- Switch ON contactor, i.e.

the unit will be connected

to the supply (POWER ON)

Control Panel key:

El - Switch OFF electronics (El)

- Switch OFF contactor, i.e.

the unit will be disconnected from the supply

(POWER OFF)

Symbols for enabling / disabling the reference

- ENABLE reference, i.e.

START DRIVE

Control Panel key:

 (when in LOCAL mode)

- DISABLE reference, i.e.

STOP DRIVE

Control Panel key:

(when in LOCAL mode)

System-dependent planning

During normal operation the control commands like SWITCH ON and SWITCH OFF,

ENABLE etc. will be preset by APC2 or fieldbus adapter. These Operating Instructions

only describe the start-up procedure via panel CDP 312 when in LOCAL mode or/and

via PC program DRIVES WINDOW.

During the start-up procedure a suitable possibility for safe shutdown (switching OFF)

will be required if there is a wrong setting of parameters. In most cases it will not be

sufficient to allow an operation of EMERGENCY STOP (EME-STOP) with a ramp

function!

How to use the DCS Documentation System

The matrix below indicates all available product documentation and its corresponding order numbers on its left columns as

well as all existing DC Drive systems on its top rows. System descriptions, Technical data and Operating instructions (as

far as they are available for the corresponding drive) are the basic documents and will be delivered together with each

drive. All other documentation has to be ordered separately

OPERATING INSTRUCTIONS

Overview This chapter contains safety instructions which must be complied

with during installation, operation and maintenance of the power

converters series DCS 600 MultiDrive. If these instructions are

not complied with, this may result in injuries (perhaps even with

fatal) or in damage to the power converter, the motor and the

driven machine. Before starting with any work whatsoever at or

with this unit, you must read the information given in this chapter.

Warnings Warnings provide information on states which if the specified

procedure for the state concerned is not meticulously complied

with may result in a serious error, in major damage to the unit, in

injury to persons and even in death.

They are identified by the following symbols:

Danger: High Voltage! This symbol warns you of

high voltages which may result in injuries to persons

and/or damage to equipment. Where appropriate, the

text printed adjacent to this symbol describes how

risks of this kind may be avoided.

● All electrical installation and maintenance work on the thyristor

power converter must be carried out by properly qualified staff

who have been thoroughly trained in electrical engineering.

● The thyristor power converter and its adjacent units must be

properly earthed by qualified professionals.

● You must NEVER perform any work on the thyristor power

converter while it is still switched on. First switch the unit off,

use a measuring instrument to make absolutely sure that the

power converter has really been de-energized, and only then

you may start with the work concerned.

● Due to external control circuits, there may be dangerously

high voltages present at the thyristor power converter even

after the line voltage has been switched off. So always work

at the unit with appropriate caution! Non-compliance with these

instructions may result in injury (or even death!).

General warning: this symbol warns you of nonelectrical risks and dangers which may result in serious or even fatal injury to persons and/or in damage

to equipment. Where appropriate, the text printed adjacent to this symbol describes how risks of this kind

may be avoided.

● When thyristor power converters are in use, the electric motors,

power transmission elements and the driven machines are

working in an extended operating range, which means they have

to cope with a relatively high loading.

● You should have made sure that all units, devices and appliances used are actually suitable for this higher loading.

● If you have to operate the thyristor power converter at a rated

motor voltage and/or a rated motor current significantly below

the figures stated in the thyristor power converter’s output data,

you must take appropriate precautionary measures to protect

the unit against overspeed, overload, breakage, etc., by modifying the software or hardware appropriately.

● For insulation testing, you must disconnect all cables from the

thyristor power converter. You should avoid operating your unit

at values other than the rated data. Non-compliance with these

instructions may cause lasting damage to the thyristor power

converter.

● The thyristor power converter possesses a number of automatic

reset functions. When these functions are executed, the unit will

be reset after an error and will then resume operation. These
