Safety and
warning notes
Always observe the safety and warning instructions in this publication.
A requirement of fault-free operation and fulfillment of any rights to claim under guar-
antee is that you adhere to the information in the operating instructions. Read the
operating instructions before you start operating the unit!
The operating instructions contain important information about service and should
be kept near the unit.

Hazard
Possible consequences: Severe or fatal injuries.
Hazardous situation
Possible consequences: Slight or minor injuries.
Harmful situation
Possible consequences: Damage to the unit and the environ-
ment.
Tips and useful information.
MOVIDRIVE®units are intended for industrial and commercial use for operating
AC asynchronous motors with squirrel-cage rotors or permanent-field AC synchronous

Disposal
Please follow the current regulations: Dispose of the following materials in accordance
with the regulations in force:
• Electronics scrap (circuit boards)
• Plastic (housing)
• Sheet metal
• Copper
etc.
• In potentially explosive atmospheres
• In areas exposed to harmful oils, acids, gases, vapors, dust, radiation, etc.
• In non-stationary applications that are subject to mechanical vibration and shock
loads in excess of the requirements in EN 61800-5-1.
MOVIDRIVE®MDX60/61B drive inverters may not perform safety functions without
higher-level safety systems.
Use higher-level safety systems to ensure protection of equipment and personnel.
For safety applications, refer to the following publications:
•Safe disconnection for MOVIDRIVE®MDX60B / 61B – Conditions
•Safe disconnection for MOVIDRIVE®MDX60B / 61B – Applications

Two types of DC link connection
System Description
2 System Description
MOVIDRIVE®drive inverters can be interconnected using the DC link circuit or a regen-
erative power supply unit. This features allows the inverters to exchange regenerative
power among themselves, which means that less electrical energy is converted into
waste heat via the braking resistors. As a result, this feature not only allows you to save
energy, but means that you can install fewer braking resistors. As a rule, only the largest
unit in the group has to be equipped with a braking resistor.
2.1 Two types of DC link connection
We differentiate between two types of DC link connection:
1. DC link connection without regenerative power supply unit.
2. DC link connection with regenerative power supply unit MOVIDRIVE®MDR60A.
The types of DC link connection with or without regenerative power supply described in
this documentation apply to the following devices:
•MOVIDRIVE
®MD_60A
•MOVIDRIVE
®MDX60B/61B
•MOVIDRIVE

compact
•MOVITRAC

•MOVITRAC
®B (MC07B055-5A3-4 ... 450-503-4)
The following sections cover the MOVIDRIVE®MDX60B/61B drive inverter only.

System Description
2.2 DC link connection without regenerative power supply unit
Only two MOVIDRIVE®drive inverters can be connected via the DC link without a
regenerative power supply unit.
You can implement the DC link connection without a regenerative power supply unit us-
ing the following connection types (→following figure):
•Connection type A: Both inverters are connected to the supply system.
•Connection type B: Only one of the two inverters is connected to the supply system.

System Manual – MOVIDRIVE® MDR60A Regenerative Power Supply Unit
2DC link connection with regenerative power supply unit
System Description
More than two MOVIDRIVE®drive inverters can be connected via the DC link with a
regenerative power supply unit MOVIDRIVE®MDR60A. To determine the permitted
number of inverters, refer to the project planning information.
The MOVIDRIVE®MDR60A regenerative power supply unit can be used with MOVID-
RIVE®drive inverters operating in regenerative mode as an alternative to braking resis-
tors. The prerequisite is a stable supply system.
The MOVIDRIVE®MDR60A regenerative power supply unit supplies the DC link circuit
of the MOVIDRIVE®drive inverter with motor power from the supply system and returns
regenerative power to the supply system from the DC link circuit. A supply system rec-
tifier is used to supply the motor power, and an inverter is used to supply the regenera-
tive power.
The MOVIDRIVE®MDR60A regenerative power supply unit does not require an auxil-
iary power supply or control signals. MOVIDRIVE®MDR60A signals that it is ready for
operation via a ready signal and a ready signal indicator.
With the MOVIDRIVE®MDR60A0370/0750 regenerative power units (sizes 3 and 4),
you can inhibit the inverter of the regenerative power supply unit using terminal X3:3 (in-
hibit). Before inhibiting the unit make sure that all connected drives have been shut
down; that is, regenerative power cannot flow back into the system.
If you inhibit the inverter during no-load operation, MOVIDRIVE®MDR60A generates
fewer losses and operates with lower power supply disturbances.
Features of a
regenerative
powersupplyunit
compared to an
inverter with
braking resistors
• Energy balance: Regenerative power is fed back into the supply system instead of
being converted into waste heat.
• Less installation work for several inverter (network and braking resistor connections).
However, a braking resistor is required to bring the drive to a controlled stop even
when there is a disruption in the supply system.
• Reduction in use of control cabinet space and fan power if the braking resistor was
previously installed in the control cabinet.
Protection and
monitoring func-
tions
• Monitoring and protection against thermal overload.
• Detection of power failure within one supply system half-wave.
• Overvoltage protection.
Take the following information into account when performing sequence control in your
system:
•MOVIDRIVE
®MDR60A0370/0750 units (sizes 3 and 4) display the operating status
"Ready" even when they are inhibited.
•MOVIDRIVE
®MDR60A1320 units (size 6) display the operating status "Error" even
when they are inhibited.
