In these cases, comprehensive tests of the complete system are required, irrespective of the specifi cations of the individual partsIn particular the following parts in inverters from heidenhain are subject to wear:Fans StandardsStandards (ISO, EN, etc.) apply only where explicitly stated in the 422 B, CC 424 Bwith modular inverterThe inverter systems from heidenhain are suitable for the heidenhain controls with digital speed control.

2 Regenerative systems need additional components, such as line fi lters and commutating reactors (see Accessories for Inverter Systems). Nonregenerative invertersWith nonregenerative inverters, the braking energy of the motors is converted to heat. This requires a braking resistor (see Accessories for Inverter Systems).Power supplyThe inverter systems are designed for connection to a TN public power supply with a voltage of 3 x 400 V; 50 to 60 Hz ( 10%). Other public grids or other line voltages must be adapted over a transformer. DC-link voltageBoth inverter systems use a rectifi er bridge circuit to convert the line power to the dc-link voltage and other auxiliary voltages for the electronics of the power modules, the controller unit, and the main computer. The rectifi ed and for regenerative systems controlled dc-link voltage is conducted through IGBTs to the motors under frequency and voltage control.

3 Control is by PWM dc-link voltage is 565 V for nonregenerative systems and 650 V for regenerative functionsIn the event of an emergency stop, heidenhain inverter systems make it possible to shut down the motors centrally over special inputs for deleting the pulse release for PWM control of the IGBTs. The controller unit controls braking until standstill. For each motor there are separate outputs to the power modules to control the brakes at required, however, drive groups can be formed to enable separate switch-off ( axes for the tool magazine). The axes are then switched off through an axis-release module. Compact invertersIn a single enclosure, UE and UR compact inverters house the rectifi ers for generating the dc-link voltage and the IGBT full bridges for up to fi ve drives. Compact inverters with internal braking resistor are available for power ratings up to 15 kW.

4 As an alternative, the internal braking resistor can be replaced by an external resistor to reduce heat generation in the electrical cabinet (not with UE 11x). Higher power ratings require regenerative special cases, an additional power module can be connected to a compact inverter (not with UE 11x). Please note that the total power consumption of the connected motors must not exceed the power of the compact inverter!The CC controller unit is connected to the compact inverter over a ribbon cable and uses PWM signals to control the Inverter SystemsHEIDENHAIN inverter systems are designed for use with QSY synchronous motors and QAN asynchronous motors from heidenhain . The inverter systems are available with power ratings of 10 kW to 80 kW. They can be supplied as compact inverters or in modular versions as regenerative or nonregenerative systems.

5 UE 112UR 2425 Modular invertersModular inverter systems consist of the following modules:One UV or UVR power supply unit including the necessary additional componentsSeveral UM power modules for axes and spindleRibbon cables and coversIn modular systems, the supply module produces the rectifi ed dc-link voltage. The IGBT full bridges are housed in the separate UM power modules. The dc-link power bar conducts the dc-link voltage to the power CC controller unit is connected to the power modules over a ribbon cable and uses PWM signals to control the IGBTs. The power supply unit is arranged the farthest to the left. The power modules are arranged to the right in order of decreasing power. Motor currentThe power modules and compact inverters are available in gradations to make it possible to match them to the required motor current and torque values.

6 In addition, the PWM frequency can be adjusted to the motor current. Please remember that very high spindle speeds require a higher PWM frequency (see Spindle).Additional power supply unitIf the 5 V power supply of the UE 2xx B does not suffi ce for the MC, CC and connected encoders, an additional UV 105 power supply unit is required. For a calculation example, see Additional Power Supply for MC and consumption of the connected modulesThe UV power supply units supply the current for the electronics of the modules. The following limit values apply:Power supplyUV 130 DUVR 1xx D15 A24 V2 A4 AThe current consumption for the electronics of the modular inverters depends largely on their power output. If several high-capacity modules are used, in rare cases the maximum permissible current for the power supply unit might be exceeded.

7 Therefore, be sure to check the current consumption for the 15-V and 24-V supplies individually. This is of particular importance when the UVR 150 D is used together with the UM 115 D. If the total current consumption exceeds the maximum value, please contact heidenhain . Ribbon cables and coversThe individual control components are connected through ribbon cables for PWM signals, power bus and unit bus. The ribbon cables must be covered to protect against interference. Ribbon cables and covers for separate power modules must be ordered in the required ribbon cables and covers for compact inverters are included in 140 D UM 115 D6 OverviewModelPageAccessoriesPageCompact invertersRegenerativeUR 230 DUR 240 DUR 242 D10, 11 KDR commutating reactorEPCOS line fi lterUP 110 braking resistor moduleAs required:SM voltage protection moduleZKF dc-link fi lterThree-phase current capacitorCMC capacitor module16161819181720 NonregenerativeUE 110UE 112 7PW 210 braking resistor(not for UE 11x)As required.
