Product Description:
The TDM 3.2-20-300-W1 is a servo drive module produced by Bosch Rexroth Indramat for the TDM Servo Drive Modules series. This unit converts the regulated DC link from a supply module into controlled three-phase power that actuates synchronous or induction motors on automated machinery. Within a multi-axis cabinet, it handles current loop regulation and fault monitoring, allowing the machine controller to command speed and torque through analog or fieldbus references. By integrating feedback evaluation and drive protection, the module supports precise positioning tasks commonly found on packaging lines, gantries, and material-handling stations. It is intended for cabinet-based motion systems that use a shared DC bus and a centralized supply module.
The drive provides auxiliary power for control sensors through three independent rails of +24 V, +15 V, and −15 V. The +24 V rail can deliver up to 50 mA, which is sufficient for encoder reference signals or small relays. The dedicated +15 V output is limited to 15 mA, supporting low-power analog devices, while the negative rail shares the same current limit. A ready output contact is rated for 24 V logic at 1 A, allowing status feedback to connected control circuitry. These low-current outputs can support small interface devices without requiring a separate auxiliary supply for every signal function. Cabinet ingress protection is limited to IP10, so the module must be installed inside a closed panel with directed airflow.
Environmental and insulation parameters limit the operating location of the module. A maximum installation height of 1000 m above sea level maintains adequate cooling and dielectric spacing. For airborne moisture, the electronics follow humidity class F, while conductor spacing follows insulation category C for mains potentials within the design voltage group. These limits suit climate-controlled production areas rather than humid washdown zones. Indoor industrial service with controlled moisture is appropriate for this module.
