Overview
Warnings
This chapter contains safety instructions which must be complied
with during installation, operation and maintenance of the power
converters series DCS 500B / DCF 500B or DCP 500B. 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 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 con-
verter 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!).

Safety Instructions
3ADW000055R0401_DCS500B_Operating Instruction_e_d
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
functions should not be used if other units and devices are not
suitable for an operating mode of this kind, or if their use might
entail dangerous situations.
Warning of electrostatic discharge:
this symbol warns you against electrostatic discharges
which may damage the unit. Where appropriate, the
text printed next to this symbol describes how a risk of
this kind may be avoided.

Safety Instructions
Notes supply information on states requiring particular attention, or
indicate that additional information is available on a specific topic.
For this purpose, the following symbols are used:
CAUTION!
Cautions are designed to draw your attention to a
particular state of affairs.
Note A note contains or refers you to additional informa-
tion available on the particular topic concerned.
You can use a switch disconnector (with fuses) in the power supply
of the thyristor power converter to disconnect the electrical components of the unit from the power supply for installation and maintenance work. The type of disconnector used must be a switch disconnector as per EN 60947-3, Class B, so as to comply with EU
regulations, or a circuit-breaker type which switches off the load circuit by means of an auxiliary contact causing the breaker's main
contacts to open. The mains disconnector must be locked in its
"OPEN" position during any installation and maintenance work.
EMERGENCY STOP buttons must be installed at each control desk
and at all other control panels requiring an emergency stop function. Pressing the STOP button on the CDP 31x control panel of the
thyristor power converter will neither cause an emergency motor
stop, nor will the drive be disconnected from any dangerous potential.
The operating instructions cannot take into consideration every
possible case of configuration, operation or maintenance. Thus,
they mainly give such advice only, which is required by qualified
personnel for normal operation of the machines and devices in
industrial installations.
If in special cases the electrical machines and devices are intended
for use in non-industrial installations - which may require stricter
safety regulations (e.g. protection against contact by
children or similar) -, these additional safety measures for the installation must be provided by the customer during assembly.

Phase coordination between electronics section and power section not necessary!
For potential isolation and for avoiding ground loops, an isolating transformer should be
installed upstream when an oscilloscope is being used.
Preventing unintended operating states / Shutting the drive down
CAUTION! As laid down in DIN 57100 Part 727 / VDE 0100 Part 727 (Preventing
unintended operating states), shutting the drive down by means of the
signals at the binary inputs DIx is not sufficient in itself as the sole
measure involved for avoiding unintended operating states or shutting
the drive down in the event of danger!
Range of application for the Start-Up Instructions
The Start-Up Instructions are referenced to the parameter settings in their as-delivered
condition (default values) and to the unit wiring as shown in connection diagram 1 or 2
(see Appendix A). In both circuit variants, the binary inputs DI5, DI7 and DI8 can be used.
They will cause the reactions at the drive as described below.
The symbols stated in this context will be repeatedly used further on in the text.
Method of functioning of the binary inputs DI5, DI7 and DI8
• Binary input DI5; designation EM STOP
In operation, DI5 must be set to logical "1“. If it is set to "0“, the alarm signal A 102
will appear. The drive will react in accordance with the function set at Parameter 917
(shutdown with ramp, with torque limit/current limit, with controller blocking and
coasting). Once ramp-down has been completed (speed feedback below n
output is reset for controlling the line contactor. After that, the EM STOP input
should be set back to "1“, the alarm message acknowledged, and the ON/OFF input
likewise be set to "0“. After that, the drive can be started anew.
•
Binary input DI7; designation ON/OFF
For connecting the drive to the mains, DI7 must be set to logical "1“. If there are no
ongoing faults, the outputs for controlling the contactors for the armature circuit and
the field circuit will be activated. If DI7 is set to "0“, the controllers will be blocked internally and the outputs reset after a time-delay.
The function which can be set with Parameter 915 (inputs DI7 and DI8 for switching
the contactors) will only be operative when the drive has been wired as shown
in connection diagram 2.
Symbols for switching the electronics or the power section ON and OFF
•
Binary input DI8; designation RUN
For starting the drive, DI8 must be set to logical „1“. This enables the reference at the
REF_SEL and RAMP GENERATOR blocks, as well as the controllers. If DI8 is set to
"0“, the drive will react in accordance with the function set at Parameter 916 (shut down with ramp, with torque limit/current limit, with controller block and coasting).
Once ramp-down has been completed (speed feedback below n
kept at zero, and the controllers blocked after a time-delay; the drive is torqueless.
Symbols for enabling / disabling the reference
System-dependent planning
If you want the drive to react with a function other than that of Parameter 916 or 917, you
have to parameterize the unit accordingly, by connecting one of the inputs or an additional one with a control pin, e.g. at the ramp-function generator.
- Example 1:
Operational ramp-up and ramp-down in the event of reference changes with the same
ramp times, shutdown via RUN with a different time.
Solution:
use second parameter set ramp times; set time at DECEL2;
establish connection from P 1707 to P 10716.
- Example 2:
Implementing an EMERGENCY SHUTDOWN or EMERGENCY STOP function.
Solution:
this function stipulated in various regulations must always be planned in dependence on
the system involved! A basic distinction must be made here between electrical and mechanical risks. Since one signal at one input is not sufficient (see above), at least one
other switch-off option must be created, e.g. by means of a relay directly switching input DI5 to "0“. This is how the power converter attempts (in accordance with
P 917), to defuse the dangerous situation. A dropout-delay contact of the relay will
then switch the power off. If the delay is small or does not match the function selected
for P 917, then certain operating states (regeneration) may, due to laws of physics,
result in the unit fuses tripping, and in extreme cases in thyristor defects.
Check the unit for damage in transit or other damage.
Install and wire unit; connect all inputs and outputs required.
Proceed in the same way for the field supply unit as well.
Check whether protective measures, earthing, screening, etc. have been taken in
accordance with the system conditions involved.
Check the rated value of the supply voltage for the electronics and the fan:
• matching transformer necessary when:
- electronics supply is not equal to 115 V/230 V
- single-phase-fan supply is not equal to 230 V
- three-phase-fan supply is not within the range of 400 V .... 690 V.
Check the rated value of the supply voltage for the armature-circuit converter's
power section; the particulars given on the rating plate must be >
line voltage.
If this condition is not satisfied, then the following applies:
- use an isolating transformer, or
- use a suitable unit.
Check the rated value of the supply voltage for the field supply unit.
(Particulars on rating plate >
Is an auxiliary transformer or perhaps a series resistor necessary?)
Check the wiring, fusing, the cross-sectional areas of the cables.
Provide an option for switching binary inputs X6: 7 and X6: 8.
Check the system's EMERGENCY STOP for proper functioning! Set the system-side
monitoring functions, and activate them. Check whether auxiliaries, such as motor fans
or unit fans, function properly; while doing this, also check for correct direction of rotation and voltage level as well!
Make sure that the existing electronics supply voltage has been set on the SDCSPOW-1 power supply board as well, using the SW1 switch.
If an encoder is being used as the speed feedback device, make sure that the correct
supply voltage has been seton the boards
