- 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.

- 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
