More Information

Overview Manuals MOD17/MOD18 TDM4 Interface Natural Cooling Application
  • Retain the TDM4-specific MOD17/MOD18 programming module
  • Maintain the W0 vertical natural-convection path and applicable baffle
  • Reproduce the TDM4 controller and feedback wiring rather than copying a TDM3 layout

TDM4.1-020-300-W0 is the 20 A natural-convection member of the TDM4 servo-drive family.

It sustains 15 A and 6 kW from the 300 V DC link, with 110 W of loss at continuous duty.

The TDM4 interface, MOD17/MOD18 identity, motor feedback and cabinet baffle position must all be preserved during replacement.

Description
TDM4.1-020-300-W0 is a naturally cooled Bosch Rexroth/INDRAMAT AC servo drive module designed for operation from a 300 V DC link.

The exact TDM4.1 technical-data entry specifies 6 kW continuous power, 110 W power loss at continuous current and a W0 natural-convection cooling arrangement.

This model must retain the TDM4-specific controller connections and the correct MOD17 or MOD18 programming module. Motor identity, feedback wiring and cabinet clearances must be checked before replacing a TDM3 or another drive generation.

Technical notes
TDM4.1-020-300-W0 shares some ratings and enclosure dimensions with TDM3 products, but its controller interface and MOD17/MOD18 programming-module family are different. W0 remains a natural-convection configuration and cannot be uprated by fitting a fan.

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 TDM4.1-020-300-W0 use a MOD13 module from TDM3.2?
No. TDM4 uses the documented MOD17/MOD18 programming-module family. Keep the module, motor and machine-function identity tied to the original TDM4 axis.
Is TDM4.1-020-300-W0 interchangeable with TDM3.2-020-300-W0 because both are 20 A W0 units?
No. The interface and programming-module families differ. Verify controller wiring, feedback, MOD identity and machine logic rather than comparing current and cooling codes alone.
Can a fan be fitted to TDM4.1-020-300-W0 to increase its continuous rating?
No. W0 is the documented natural-convection variant. A fan retrofit does not create the separately defined W1 electronic configuration or change its official current table.
Why can TDM4.1-020-300-W0 remain in current reduction after replacement?
Check the Ired input, controller assignment, programming module, reference potentials and saved machine logic. The symptom is often an interface or parameter issue, not a power-stage fault.
What prevents TDM4.1-020-300-W0 from cooling correctly at the left edge of a drive package?
A missing cooling baffle can allow the natural convection path to bypass the heatsink. Apply the documented baffle rule and maintain vertical clearance.
Can TDM4.1-020-300-W0 operate as a standalone mains drive?
No. It requires the DIAX 300 V DC link and control supplies from the compatible system supply module, plus the matched motor and programming module.
Why can TDM4.1-020-300-W0 show unstable speed after moving the original electronics?
Recheck zero-point adjustment, command reference, feedback polarity, shield termination and MOD17/MOD18 identity. Mechanical fit does not preserve the TDM4 control-loop setup.
