Product Description:

The TDM1.3-100-300-W1 is a servo drive module from Bosch Rexroth Indramat and belongs to the TDM Servo Drive Modules series. It interfaces with the MAC 112D-.-FD-.-C synchronous motor, converting low-level velocity commands into regulated three-phase output so closed-loop axes can reach commanded speeds with stable regulation. Within an automation cell, this module forms the link between the CNC or PLC motion card and the rotary load, delivering controlled current while also reporting operating status for system diagnostics. This arrangement allows the motion system to supervise drive response and fault status during operation.

The power stage uses a DC link of 300 VDC, providing enough headroom for deceleration energy to return to the common bus. Command inputs E1 through E4 share a scaling factor of 2000 rpm/10 V, allowing uniform velocity tuning across multiple channels. Peak and continuous current capability is listed as 100/75 A, and thermal loading is monitored through the MA test point, which produces 0.05 V/A so external meters can read real-time phase current. An auxiliary blower fed from 220 VAC moves air directly across the heat sink, and the module has a panel depth of 390 mm so space can be reserved behind the drive for airflow.

The installation requires a minimum frontal clearance of 80 mm and a cabinet height of at least 400 mm so the fan can exhaust warmed air without recirculation. The ASQ relay contact inside the drive is rated at 24 V, 1 A for interfacing with external fault lamps or interlocks. Additional protection includes a starting-lockout threshold of 20 mA or 0.5 W to prevent accidental restart, and the logic accepts velocity references within the operating range of the connected motor. A unit width of 105 mm lets multiple modules sit side by side on a standard mounting rail without exceeding typical enclosure spans.
