Replacement & Alternative Selection

1. Direct drop-in replacement: Same-series CDE32.004.C2.x. Hardware compatible for all C2.x revisions, firmware V.3 preferred. Discontinued, only NOS / used spare parts available.
2. Domestic Chinese alternatives

Keep CANopen bus: Inovance SV660PS2R8I (220V,4.4A CANopen). Complete re-wiring and full reprogramming required.

Upgrade to EtherCAT allowed: Inovance SV680, HCFA X3EA. Motion logic must be migrated; LUST project files cannot be imported directly.

⚠️ Important: DriveManager project files are incompatible with third-party servo drives. Motion PLC and CAM profiles need full redevelopment.

LTi-LUST CDE32.004.C2.3 Physical Hardware & Interface Description (corresponding to reference diagram)

Diagram shows CDE3000 series layout; mechanical layout fully matches CDE32.004.C2.3 (BG1 size)

Physical Layout Top-to-Bottom

1. Heatsink for optional internal brake resistor: Brake chopper integrated on drive. High-energy applications need external brake resistor connected to BR+ / BRpower terminals.
2. DIP switch S1: CANopen termination resistor. Set ON = activate 120Ω termination resistor. Terminate only at physical bus end-nodes.
3. Expansion Slot X8: For optional Profibus-DP board. No EtherCAT option. Blank slot = CANopen-only configuration.
4. X4 SIO-RS232 Debug (9-pin D-Sub): KP200-XL panel or USB-RS232 converter to PC. Only DriveManager V3 supported; V4 software cannot communicate with this hardware.
5. X5 CANopen DS402 (9-pin D-Sub): CAN_HIGH, CAN_LOW, CAN_GND; PDO / SDO multi-axis networking. Bus termination controlled via S1 DIP switch.
6. X7 Primary Motor Encoder (15-pin D-Sub): TTL/HTL incremental, SSI absolute motor encoder. +5V output max total 150mA, watch for cable voltage drop; supports PTC / KTY motor temperature input.
7. X6 Resolver Interface (9-pin D-Sub): Direct resolver connection without external converter; multiplexed for motor temperature sensing.

Front-panel LED Indicators

RDY: Green, Drive Ready

ERR: Red, Fault present; read fault history with DriveManager

COM: Blinking, CANopen bus communication activity

Critical Wiring Notes (Common field pitfalls during repair-replacement)

1. Control 24V must be isolated external supply (≥30W rating). Never derive from main-circuit rectified bus.
2. Set DIP-switch S1=ON only for first and last physical node of CANopen bus; intermediate nodes set S1=OFF.
3. Total +5V encoder supply limit 150mA at X7; avoid over-loading with dual high-current encoders.
4. Brake resistor minimum resistance:100Ω, power rating ≥100W. Never use resistor below 100Ω, risk of destroying on-board brake chopper.
5. Max motor-cable length for TTL encoder:50m. Install output reactor for longer cables; all signal shielding single-end grounded inside control cabinet.
