General remarks
The following symbols should assist you in handling the instructions:
Advice, tip !
General information, note exactly !
The requirements for successful commissioning are correct selection of the device, proper planning and installation. If you have
any further questions, please contact the supplier of the device.
Capacitor discharge !
Before performing any work on or in the device, disconnect it from the mains and wait at least 15 minutes until the capacitors have
been fully discharged to ensure that there is no voltage on the device.
Automatic restart !
With certain parameter settings it may happen that the frequency inverter restarts automatically when the mains supply returns
after a power failure. Make sure that in this case neither persons nor equipment is in danger.
Commissioning and service !
Work on or in the device must be done only by duly qualified staff and in full compliance with the appropriate instructions and
pertinent regulations. In case of a fault contacts which are normally potential-free and/or PCBs may carry dangerous voltages. To
avoid any risk to humans, obey the regulations concerning "Work on Live Equipment" explicitly.

The inverter solution for medium voltage motors
(only with squared load torque)
The ATV61 adds even more numerous functions to the well-known
and extremely well-proven features of the Altivar inverter range. It
presents itself to the user as being even more robust with improved
operation and having a clearly wider range of user possibilities.
The choice comprises the ATV61 frequency inverter in
various cubicle designs in addition to the built-in and wallmounting designs.
The basic design of the Altivar customized enclosure
complies with protection degree IP23 and IP54 and
includes a main switch, mains fuses, AC choke, sinus filter
and motor terminals. Further installed components, such
as circuit breaker, line contactor, various control options,
alternatively with a field bus, safety relay, cubicle heating,
and much more, see ATV61 catalogue.
8 P02 501 EN.01/01 07/2010 8 P02 501 EN.01/01 07/2010
In addition, special designs are available such as changed
cubicle colour, cubicle cooling via an air conditioner or an
air/water heat exchanger, and customer-specific control
equipment.

Application
There is a wide application area for medium voltage motors. Many existing systems from approx. 200 kW use
medium voltage motors for pumps or fans. The flow control often takes place by simple mechanical
components like valves and flaps and so it represents a very inefficient operation.
Also for new systems medium voltage motors with a power range below 1 MW are used. That applies mainly to
pump technology for petrochemical and geothermal applications. The length of the motor cables often
exceeds more than 1000 m but when using medium voltage motors undesired voltage drops at the lines can
be avoided.

Advantages of the speed control
Restriction
The restriction of the flow rate is common practice. Thereby the
system characteristic is changed by increasing the friction due
to reduction of the cross section. The losses arising due to the
restriction are proportional to the area Q x H.
Bypass
In case of a pump operated with constant speed the flow rate
can be controlled in such a way that only those part is
separated which is required for the system and the residual
rate is returned to the intake area. The arising losses due to the
returning flow medium is proportional to the area Q x H.

Speed control
Regarding technic and energy the most advantageous
possiblity for changing the flow rate is the operation of the
centrifugal pump with variable speed. This operating mode
leads to a parallel displacement of the pump characteristic. In
case of this method additional, continuous actuators in the
system are not necessary because the pump also assumes the
part of the actuator with integral function.
At the operation of a centrifugal pump the effect occurs that
the efficiency remains within its optimum range for speed
control ranges from 1:3 to 1:5. This property of the centrifugal
pump is the basis for the fact that speed control is a very low
price variant in comparison with other methods. Because of the
achieved energy saving the costs for purchasing the frequency
inverter amortize within short time.
Further advantages of the speed control are avoiding current peaks in the supplying mains due to direct-online starting as well as preserving the mechanics of the pump and avoiding shock pressures in the hydraulic
system by controlled acceleration and deceleration along the set ramps.

Speed control of medium voltage motors
A medium voltage frequency inverter is not the only solution for the speed control of medium voltage motors.
Based on standard well proven low voltage components the Altivar transformer solution is a very economical
alternative.
There are two configurations in principle:
1. The drive is connected in the medium voltage line of the motor
2. The drive is supplied by low voltage and operates a medium voltage motor
8 P02 501 EN.01/01 07/2010 8 P02 501 EN.01/01 07/2010
Thereby the medium voltage value of the motor is not defined because accurate adaptation takes place by the
transformers.
These ATV61 are available from 110 kW and above!

The ATV61HC••Y387 frequency inverter is supplied via a
step-down transformer with low voltage from a medium

12-pulse supply
The following inverters are standard equipped with two parallel input rectifiers and therefore are suitable for a
12-pulse rectification
ATV61HC50N4D387…HC63N4D387
ATV61HC50Y387…HC80Y387
The supply results from a separate transformer with two out-of-phase secondary windings (e.g. Yy6d5).
On the main side of the transformer the 5th and 7th current harmonics are practically non-existent as they have
been cancelled by the shifted transformer windings.
The transformer must keep to the following tolerances in order to guarantee a constant current sharing:
Tolerance of the transmission rates ± 0.3 % of r
Tolerance of the relative short circuit voltage ± 5.0 % of v
The nominal output voltage of a transformer is specified at no load operation. Therefore this value has
to be appr. 5 % higher than the rated voltage of the drive.

*) Line chokes are only necessary if a trans-
former is used for several inverters or if the
transformer power is notedly larger than the
inverter power.
In case of 12-pulse supply the radio frequency interference filters, which are built into the ATV61 as
standard, must be reconnected onto setting "IT mains".

Technical data of the output transformer (step-up)
A three-phase resin-encapsulated transformer has to be used.
Select the primary voltage as well as the secondary voltage (no-load voltage) of the transformer in the table
below for motors with a nominal voltage of 6kV:
Primary voltage
Input voltage of the frequency inverter

ATV61HC••N4D387 at 400V mains 365 V 6450 V 6550 V

ATV61HC••Y387 with step-down transformer 670 V 6500 V 6500 V
The no-load voltage of the transformer can be calculated for motors with different nominal voltage as follows:
Transformer no-load voltage = Secondary transformer voltage (acc. table) * nominal motor voltage / 6000 V
Example: ATV61HC••N4D387 at 400 V mains, with step-up transformer with 4 % v
nominal voltage
Transformer no-load voltage = 6450 V * 4160 V / 6000 V = 4472 V

2. The monitoring of the fuses is used to protect the inverter against unbalanced load. It must act on mains

the inverter monitors the mains voltage. Therefor set the parameter IPL "Input phase loss" to "YES".
