Product Description:

KDA 3.2-050-3-L0S-W1 is a modular KDA series spindle drive. It is produced by Bosch Rexroth. The drive has a slot for a programming module. Drive software and its operating parameters are stored on this module. This module can be easily inserted and removed. In case of a drive fault, operators can move the module to another drive. This helps to reduce downtime and speeds up commissioning of the replacement drive. The overall effect is faster troubleshooting and higher productivity, which leads to higher profitability. KDA series drives units are fitted with a blower that helps to improve cooling. The blower increases the airflow over the rear-mounted heat sink. The heat sink itself is outside the drive enclosure, which reduces the size and cost of the drive enclosure. This also saves costs by requiring enclosures without internal cooling units.

Power supply for the blower is 220 Volts AC. The rated and continuous output current ratings for the KDA 3.2-050-3-L0S-W1 drive are 50 Amps and 35 Amps respectively. The DC bus voltage for the drive unit is 300 Volts DC. Speed command values for connected 2AD or 1MB motors can be sent to the drive via a SERCOS high-speed communication interface. The drive is also equipped with an auxiliary RS 232 serial interface for serial connectivity. To aid drive identification, Bosch attaches a sticker to the side of the unit and a rating plate in front of the unit. The rating plate is visible even after the drive is installed inside an enclosure. The permissible temperature ranges for operation and storage of this KDA series spindle drive are 5 to 45 ⁰C and -30 to 85 ⁰C.
