II. Electrical Specifications (Uniform Power for W050A)

Main Power Supply: Three-phase AC 230V ± 10%, 50/60Hz, control auxiliary power single-phase AC 230V

DC Bus: DC 310V, PWM carrier 18kHz; Version A has no built-in braking, large power braking requires external external braking resistor / braking unit

Overall Size: 355×115×230mm, Net Weight 2.85kg, IP20 cabinet installation

Operating Environment: 0~45℃ full load, >45℃ reduced power usage, altitude ≤ 1000m without derating

III. Unique Features of DA01 Board

Only Analog Control: Upper PLC / frequency converter sends ±10V voltage for speed regulation, pulse + direction for point operation, old-style numerical control retrofit standard configuration

Encoder Interface: Compatible with TTL incremental encoder, rotary transformer for two types of motor feedback

No Fiber SERCOS Port, cannot form multi-axis fiber serial networking, unable to connect to Schmersal MTX bus system

Fault Passive Alarm Contacts, Brake Control Output Integrated in the Board

IV. -01 Suffix Explanation

-01 = Built-in V01 firmware card, same model DA01-01 complete machine can be directly replaced; replacing DA01-02 requires checking motor parameters, firmware can be downward compatible with hardware

If you need to change the bus control: directly replace the same base DL/RL board card, shell power is universal

V. Applicable Equipment

Old-fashioned ordinary CNC lathes, grinders, non-standard single-machine automation, old-fashioned hydraulic to servo equipment (upper level only has analog output, no SERCOS bus)

VI. Replacement Maintenance Key Points

W050A (without built-in brake) ≠ W050B (with built-in brake), A cannot be directly substituted for B, braking circuit configuration is different

Power off static ≥ 20 minutes, fully discharge bus capacitor before disassembling for maintenance

DA01 can be non-destructively replaced with the same W050 base RL/DL/RS board, after replacing the board, the corresponding firmware should be reinstalled as needed
