Product Description:
The TDM 3.2-100-3-A0S-W1 is a servo drive module produced by Bosch Rexroth Indramat as part of the TDM Servo Drive Modules series. Within an automation cell, this module closes the current and velocity loops for an Indramat synchronous motor, translating motion commands into regulated armature current while monitoring internal temperature and supply status. Its analog ±10 V speed interface allows direct coupling to PLC or motion card outputs, and the built-in RS-232C auxiliary port supports parameter exchange and diagnostic readback over a serial link.
The drive draws power from a shared DC bus operating at 300 V DC and delivers a rated armature current of 100 A for rapid torque demands. Continuous operation is limited to 70 A, so thermal loading stays within limits during sustained use. Forced-air cooling is provided by an integral blower that moves 32 l/s of air across the fin stack against a back pressure of 30 Pa; the fan is supplied from an external 220 VAC, 50/60 Hz line. Vertical mounting keeps the airflow path unobstructed, while the IP10 housing is intended for installation inside an electrical cabinet. A ±15 V internal rail powers feedback electronics, and the unit accepts speed commands through the analog interface without additional conversion hardware.
Control electronics receive system power through a 24 V utility connection that can source up to 1.4 A, and analog sensing circuits require only 160 mA from the ±15 V measuring supply. The module can operate at ambient temperatures up to 55 °C and at installation altitudes up to 1000 m without derating. With a mass of 17.1 kg, the unit is suitable for panel mounting when enough space is left around the heat sink exhaust. This layout helps maintain steady airflow through the cooling path and keeps nearby components from blocking ventilation.
