Product Description:

The DDS02.1-A150-DL01-01-FW belongs to the DDS Drive Controllers series from Bosch Rexroth Indramat. It is a digital AC servo drive controller that regulates current and velocity for synchronous and induction motors in factory automation cells, material-handling lines, and packaging machines. By processing encoder signals and issuing timed pulse patterns to the power stage, the unit closes the electrical loop between the PLC and the mechanical load. In automated equipment, this controller serves as the link between the higher-level command system and the motor's electrical behavior, allowing the connected axis to respond accurately during positioning and speed-controlled operation.

The drive can supply up to 150 A of continuous output current, allowing it to pair with high-torque servo motors without losing dynamic response. Command data reach the controller through single-axis position control, so each unit governs one motor and keeps the control structure straightforward. Motion feedback is returned through digital servo feedback, which supports high-resolution position verification and automatic parameter matching. Because the feedback channel is digital, the drive can evaluate rotor position data directly and adjust output with stable repeatability during changing load conditions. Thermal energy is removed by air from outside the control cabinet, so cooling airflow is drawn directly from the plant environment rather than recirculated inside the enclosure, which helps reduce heat buildup around nearby electronics.

The controller carries Function ID 01 and Function ID Version 01, which identify the installed function set for this unit. It is part of Line 02, indicating the second DDS product line and its matching back-plane format. Within a modular drive assembly, these codes help distinguish this controller from similar units that use a different function set or product line. They also keep the unit description clear when the controller is integrated with other compatible DDS components in the same drive arrangement.

Fault / Error Code What it Means Typical Corrective Action
F205 Cam-shaft (operating-mode) data invalid when drive tries to start. Reload or re-create the cam-shaft data set, store it in parameters S-0-0032…35, then press S1 (or issue Reset Class 1 Diagnostics) and re-enable.
F207 Drive was commanded to switch into an un-initialised operating mode. Enter a valid mode in S-0-0032…35 before enabling; save, reset, then apply Control Enable again.
F218 Heatsink over-temperature shutdown. Lower cabinet temperature (< 45 °C), clear airflow, clean or replace blower; wait for cool-down and reset.
F219 Motor over-temperature (thermistor > 155 °C). Reduce load or duty-cycle, verify external blower, inspect thermal-sensor wiring; re-enable after motor cools.
F220 Internal brake / bleeder resistor overload—too much regenerated energy. Lengthen decel ramps or install external brake resistor; clear fault after temperature normalises.
F226 DC-bus undervoltage in power stage. Check mains for brown-outs and be sure Drive Enable is removed before AC power is lost; restore supply, then reset.
F228 Excessive deviation—axis cannot follow command (following-error too large). Reduce commanded acceleration/velocity, check mechanics for binding or backlash, retune velocity/position loops.
F229 Encoder 1 quadrant error—motor-feedback plausibility fault. Inspect encoder cable/shielding, reroute away from power lines, replace encoder or interface if error persists.
F230 Encoder 1 signal frequency exceeded interface limit. Limit maximum speed, fit lower-PPR encoder, or use a higher-bandwidth feedback card; clear fault and restart.
F234 Emergency-Stop activated (+24 V lost at E-Stop input). Find and clear E-Stop cause, restore +24 V chain, then perform Reset Class 1 Diagnostics before enabling.
