More Information

Overview Manuals Current Duty Control Supplies Generation Match Application
  • Size the spindle duty from the documented 70 A continuous capability rather than the 100 A current class alone
  • Keep KDA3.3 hardware and AS3 software compatibility separate from the visually similar KDA3.2 generation
  • Verify the +24 V and ±15 V control-supply loading before reusing an existing DIAX supply arrangement

KDA3.3-100-3-A00-W1 is a Bosch Rexroth / INDRAMAT modular main spindle drive controller in the INDRAMAT KDA 3.3 family.

The original KDA3.3 technical table gives 70 A continuous current, 1.4 A load on the +24 V control supply and 160 mA on the ±15 V measuring supply for the 100 A version; W1 specifies a 220 V, 50–60 Hz blower.

Keep the KDA3.3 hardware generation, AS3 software, motor data, A00 interface and blower voltage together when replacing a KDA3.2 or another KDA3.3 variant.

Availability, condition, price, and shipping time for KDA3.3-100-3-A00-W1 are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • Use 70 A as the documented continuous-current limit
  • Check spindle acceleration and overload separately from continuous cutting duty
  • Verify the supply module can carry simultaneous spindle and feed-axis demand
  • Allow 1.4 A on the +24 V control supply for this current class
  • Allow 160 mA on the ±15 V measuring supply
  • Include every external control load when checking the DIAX supply budget
  • Confirm KDA3.3 hardware before substituting a KDA3.2 controller
  • Use the AS3 software and parameter module approved for the exact axis
  • Match the A00 interface and W1 blower voltage to the installed machine
  • Analog-controlled machining-center main spindles
  • Machine-tool spindles with sustained 70 A drive duty
  • DIAX modular spindle systems using matched AS3 programming modules

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can KDA3.3-100-3-A00-W1 directly replace KDA3.2-100-3-A00-W1?
Do not assume so. Confirm the hardware design generation, AS3 software release, motor combination, control-supply loading, connector allocation and machine documentation before using a KDA3.3 unit in a KDA3.2 installation.
Why does the 70 A continuous rating matter when selecting KDA3.3-100-3-A00-W1?
The 100 A code identifies the rated-current class, while 70 A is the documented continuous capability. Base sustained spindle torque and cabinet heat calculations on the continuous rating and the actual duty cycle.
Can KDA3.3-100-3-A00-W1 support a spindle encoder for C-axis operation?
Not through the A00 option. A00 denotes analog command with no auxiliary encoder input and no auxiliary interface; a C-axis design requiring those functions needs the correct alternative option code.
Why can KDA3.3-100-3-A00-W1 fail to reach the ready state even when the 300 V DC bus is present?
The 300 V link does not supply all control electronics. Check that the DIAX supply delivers the model’s 1.4 A +24 V control load and 160 mA ±15 V measuring-supply load after all other modules and external loads are included; also inspect the control-bus connections for voltage drop or interruption.
Can a W1 blower be replaced by a mechanically similar U1 blower on KDA3.3-100-3-A00-W1?
No. W1 specifies 220 V at 50–60 Hz, whereas U1 denotes the 115 V blower arrangement. Match the suffix and blower nameplate to the cabinet supply.
Why can KDA3.3-100-3-A00-W1 lose its machine-specific setup after an electronics swap?
The software and user parameters reside in the matched AS3 programming module. A missing, incompatible or incorrectly identified AS3 module prevents the replacement from reproducing the original axis configuration.
What environmental condition most often invalidates a KDA3.3-100-3-A00-W1 cabinet installation?
The IP10 controller depends on a protected cabinet and non-condensing operation. Check temperature, altitude derating, humidity, contaminants and forced airflow rather than treating the drive as a sealed field device.
