DDS02.1-A050-R/S002

DDS02.1-A050-R/S002 is manufactured by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. It belongs to line 02 and is version 1. The controller has a rated current of 50 A and provides 50 A of continuous current. Its peak current and peak output current are also 50 A, indicating that its maximum output does not exceed its continuous-current rating. Resolver feedback supplies motor position and speed information for closed-loop control.

The DC bus operates at 300 VDC to supply the controller’s power stage. Its DC bus terminals require 3 Nm of tightening torque. The motor power connection uses an M6 terminal thread and requires 5 Nm of tightening torque for a secure electrical connection. The starting-lockout input consumes 1.5 W when used to inhibit drive startup.

The basic-unit current at both -15 V entries is 150 mA, while the current at both +15 V entries is also 150 mA. The two +24 V basic-unit current ratings are each 500 mA. External air from outside the control cabinet cools the unit. The IP20 protection category guards against finger contact and solid objects larger than 12.5 mm but does not provide water protection.

The controller operates from 0-45ºC and can be stored from -30-85ºC. Its maximum installation elevation is 1,000 m.
