Our single-axis devices combine mains supply, DC bus and inverter in a single unit. The filter elements and the brake chopper are integrated in the servo inverter and allow autonomous use in distributed control cabinet installations. By using corresponding footprint filters (up to 55 kW), greater interference suppression can be achieved without additional mounting area.
The use of a mains choke slightly reduces the mains voltage at the Mains choke input of the inverter - the typical voltage drop across the mains choke at the rated values is around 4%.
In the course of the product update, we have revised and simplified the assignments of the inverters. Hence, we can provide a uniform assignment for all inverters of our product range. This makes it easier for the customer to select the right component.
A mains choke is an inductive resistor which is connected in the mains cable of the power supply module. The use of a mains choke provides the following advantages. Fewer effects on the mains: The wave form of the mains current is a close approximation to a sine wave. Reduction in the effective mains current: Reduction of mains, cable and fuse loads.

Up to a rated current of 23.5 A, the Servo Drives 9400 consist of an axis module and an installation backplane.
The backplane can initially be mounted in the control cabinet without the axis module.
This mechanical structure is also used for power supply modules up to a rated power of 17.5 kW and for regenerative power supply modules for a supply power of up to 27 kW, which simplifies installation.
This also offers additional advantages in terms of reduced spare part inventories and time savings in the event of drive replacements.
Further features of the installation backplane: A brake module for a 24 V DC, 2.5 A brake can be installed as an option and Shields for power and control cables can be connected.
Running the Single Drive axis module in a DC-bus connection (multiaxis application) requires retrofitting the DC busbar system and using DC fuses. For retrofitting the DC busbar system and the DC fuse have to be installed in the axis module's installation backplane, which is provided with the appropriate fixtures. The DC fuse required is part of the DC busbar set. Spare fuses are not contained in the scope of supply.
An intelligent motor brake logic system is included as standard in the axis modules' device software in the form of a function block. The brake modules are available in numerous designs. The optionally integrable brake modules enable a DC 24 V, DC 180 V or DC 205 V brake to be easily connected and this logic to be used.
For axis modules up to 23.5 A, the brake module is integrated into the installation backplane. For axis modules above 32 A, the brake module is integrated into the axis modules.
Due to their functional principle, the motor brake in Single Drives cannot be released if there is no mains or DC-bus voltage. Brake modules which can be activated externally are therefore provided for a 24V brake.
Brake resistors can be assigned to the Single Drive axis modules. For 230 Vmains voltage a different brake resistor assignment applies. Two resistors should be connected in parallel for some combinations.
RFI & Mains Filter
RFI filters and mains filters enable compliance with the interference voltage categories of the European standard EN 61800-3. There a distinction is drawn between category C1 and category C2. Category C1 describes the use on public supply networks. Category C2 describes the use of drives which are intended to be used for industrial purposes in areas also comprising residential areas.
A mains filter is a combination of mains choke and RFI filter in a single housing. It reduces line-bound noise emission into the mains, thus ensuring that the line-bound interference voltage is reduced to a permissible level according to EN61800-3.
A sinusoidal filter in the motor cable limits the rate of voltage rise and the capacitive charge/discharge currents that occur during inverter operation. In combination with the specified line filter, the EMC requirements of the limit class C2 for conducted noise emissions are still met, even if longer shielded or even unshielded motor cables are used.
Application range: Only use a sinusoidal filter with standard 0 to 550 V asynchronous motors, Operation only with V/f or V/f22 characteristic control, Set the switching frequency permanently to the specified value & Limit the output frequency of the Servo Drives 9400 to the specified value.
24 V Power Supply & CAN Bus Connector
Multi-axis applications with Multi Drive axis modules require an external power supply unit to feed the control electronics. Depending on the number of axis modules, power supply units with a rated current of 5, 10 or 20 A can be selected with a voltage supply of 1 x 230 V AC or 3 x 400 V AC. Single Drive axis modules generally do not require the use of the power supply unit. If, however, separate power supplies are needed for the control electronics and power section in a single-axis application, the same power supply units can be used.
The connector is used to connect the CAN to inverters which are provided with a Sub-D connection for the CAN bus. An integrated CAN terminating resistor can be switched on/off. Internal spring terminals make the use of special mounting tools superfluous. The switch setting can be read from two sides.
USB Diagnostic Adapters
The operation, parameter setting and diagnostics of the Inverter Drives 8400 and the Servo Drives 9400 via the L-force diagnostics is made with the keypad X400 or a PC. The connection of a PC can be made via a USB interface and the USB diagnostic adapter.
For connecting the USB diagnostic adapter with the L-force diagnostics interface (DIAG) tat the inverter, three different connecting cables are separately available in the lengths 2.5 m, 5 m and 10 m. The connection can be established during operation. The engineering tools EASY Starter or Engineer can be used to carry out the operation, parameter setting or diagnostics of the inverters. Both tools have simple intuitive surfaces. This enables a quick and easy commissioning.
Optionally to the USB diagnostic adapter, the PC system bus adapter can be used. For this purpose, a CANopen interface must be available at the inverter.

The BFK471-25 brake is only to be actuated with a bridge half-wave rectifier (included in the scope of supply). The power input during the release is 440 W for 1.3 sec., then it is reduced to 110 W. The spring-applied brake is designed for the conversion of mechanical work and kinetic energy into heat. Due to the static brake torque, the brake can hold loads without speed difference.
The Setpoint Potentiometer serves to set the required torque or exciting current. As a nominal output voltage of 24 V is required, the controller has to be adapted to the mains via the transformer supplied. The control board ensures that, despite varying coil temperature and the resulting variation in coil resistance, the current is constant. This enables the torque to be kept constant. For certain applications, it is also possible
