KDS1.1-30-300-W1

The Bosch Rexroth Indramat KDS1.1-30-300-W1 module from the KDS Servo Drive Modules series represents a precision Standard family solution featuring a Current Rating of 30 A and a single Differential Input. This drive incorporates an External Heat Exchanger paired with Forced Ventilation cooling to maintain stable operation under full load. Factory-installed is a MOD Programming Module (Model Code 1) alongside 2 Summing Inputs, enabling flexible torque-controlled or current-limited modes. Constructed to Humidity Classification F, this KDS1.1 variant upholds Bosch Rexroth’s strict quality and performance standards.

Electrical and thermal protections are deeply integrated. The module remains active for up to 300 ms after a power-off command, ensuring safe ramp-down of connected servomotors. When ambient temperatures rise between 45 °C and 55 °C, internal torque and current automatically derate by 2 % per degree, safeguarding against overheating. The drive must be mounted in a fully enclosed control cabinet and properly earthed before commissioning; a link-circuit bus bar facilitates power connections to adjacent drives while maintaining high-voltage isolation at terminals L1, L2, and L3.

Connectivity and maintenance considerations are equally robust. Feedback loops require a shielded cable not exceeding specified lengths, and the unit can interface with KDS and non-KDS devices alike in multi-axis installations. After power disconnection, a minimum 15-minute cooldown period is mandatory to preserve heat-exchanger integrity. To prevent electromagnetic interference, installation sites should avoid proximity to high-frequency radio transmitters, ensuring reliable drive performance over prolonged service life.
