6️⃣ How to Use 

Step 1: Mount the Drive and Motor
Install the ASD-B3-0721-L or -E vertically inside a shielded control cabinet. Leave at least two inches of clearance above and below for airflow. Mount the ECM-B3M-C20807RS1 motor securely on a solid surface. The 80mm frame with 90mm mounting hole spacing fits standard brackets . Align the 19mm shaft properly with your load to prevent vibration.

Step 2: Wire the System
Connect the motor power cables (U, V, W) to the drive outputs. Attach the encoder cable to the designated feedback port. Connect your 220VAC power supply to the drive input terminals . Wire control signals from your controller to the CN1 connector. For the -E model, connect EtherCAT communication cables.

Step 3: Configure Parameters
Use the digital keypad or ASDA-Soft software to set motor type and control mode . Access parameter P1.001 to select control mode: 0 for position (PT), 1 for position (PR), 2 for speed, and 3 for torque . Run the auto-tuning function to optimize gain settings. Configure the five notch filters for resonance suppression.

Step 4: Perform a Test Run
Before connecting the load, run a low-speed JOG test to verify proper motor rotation. Check for unusual noise or vibration. Confirm that all alarms are clear and the system responds correctly to commands.

Safety Tips
Always disconnect power before wiring or maintenance. Ground the drive and motor properly to a class-3 ground system with resistance under 100Ω . Never touch the motor shaft during operation. The STO function protects personnel but does not replace proper safety procedures .

Maintenance Guidance
Keep the drive ventilation slots clean and dust-free. Check cable connections periodically for tightness. Inspect the oil seal for wear and replace if needed. Store spare components in dry conditions. Do not disassemble the drive when power is on.
