Product Description:
The TDA 1.3-100-3-AP0 is a main spindle controller from the TDA Main Spindle Controllers series manufactured by Bosch Rexroth Indramat. Designed for CNC and machining center spindles, it converts DC link energy into three-phase output and processes encoder feedback to regulate rotational speed and position. When paired with a compatible power supply and drive, the unit provides closed-loop control for cutting, drilling, and grinding operations. This arrangement supports stable spindle response during changing load conditions and repeated speed adjustments.
The drive section is rated for a peak line current of 100 A, while its DC link operates at 300 V. During continuous duty, the module holds a steady armature current of 70 A, which helps set cabinet thermal requirements and current handling for connected components. Speed commands enter on a differential input that accepts Analog ±10 V, allowing simple integration with PLC analog outputs or legacy motion cards. An IP10 housing limits ingress of larger objects and relies on the control cabinet for broader protection. Encoder inputs can accept either spindle feedback or a secondary motor channel, so the controller can support rigid-tapping spindles or dual-motor heads without external converter cards.
The logic stage draws 1.4 A from the 24 V machine supply, and operating temperature is maintained at a nominal level of +45 °C with derating up to +55 °C. At just 10.5 kg, the unit fits mid-sized control cabinets without additional bracing, and its construction supports installation heights up to 1000 m. Start-up diagnostics use a 15 V, 160 mA test line to check control functions before normal operation. Storage between -30 °C and +85 °C helps protect internal components during shipment or long-term downtime.
