Frequently Asked Questions
Q: What is the main advantage of the 24-bit absolute encoder?
A: The 24-bit resolution (16,777,216 pulses/rev) provides sub-micron positioning accuracy and eliminates the need for homing after power loss. Position data is retained even when power is disconnected, reducing downtime and improving operational efficiency.
Q: Does this motor include a holding brake?
A: No, the "RS1" suffix indicates this model is without brake. For applications requiring position holding (such as vertical axes), select the ECM-B3M-EA1315SS1 variant with integrated brake.
Q: What is the IP rating of this motor?
A: IP65 protection rating means the motor is dust-tight and protected against low-pressure water jets from any direction when used with proper waterproof connectors and the integrated oil seal.
Q: What drives are compatible with this motor?
A: This motor is designed for Delta ASDA-B3 series servo drives, including ASD-B3-1521-L (pulse train), ASD-B3-1521-M (CANopen), ASD-B3-1521-F (EtherCAT), and ASD-B3-1521-E (EtherNet/IP).
Q: What is the operating temperature range?
A: The motor operates reliably in ambient temperatures from -20°C to 60°C, suitable for a wide range of industrial environments.
Q: What torque does this motor deliver?
A: Rated torque is 4.77 N*m at 2000 rpm, with peak torque of 14.32 N*m (3x overload capacity) for dynamic acceleration and load handling.
Q: What is the difference between EA1315RS1 and EA1315SS1?
A: The "RS1" suffix indicates resolver/absolute encoder without brake; the "SS1" suffix indicates the same encoder with integrated holding brake. Choose based on application requirements for position holding.
Q: Is this motor suitable for continuous high-speed operation?
A: With a rated speed of 2000 rpm and maximum speed of 3000 rpm, it is well-suited for many high-speed applications. Continuous operation at peak torque may require thermal management considerations.
