Frequently Asked Questions
What do the letters L, M, F and E mean on the ASDA-B3?
L is the standard model with pulse input, analog command and RS-485. M adds CANopen. F adds DMCNET. E adds EtherCAT. The B3A sub-series adds STO safety and a PROFINET option.
Which motor pairs with ASD-B3-0721-L?
The Delta ECM-B3M series at the same power rating. For ASD-B3-0721-L that is the ECM-B3M-C20807 motor, available with or without a holding brake.
How is the ASDA-B3 different from the ASDA-B2?
The B3 is the newer generation. The encoder goes from 17-bit to 24-bit, the motor maximum speed rises from 5000 to 6000 rpm, peak torque rises from three times to three and a half times rated, and the motor sealing improves from IP65 to IP67.
Can ASD-B3-0721-L be used with an older ECMA motor?
No. The ASDA-B3 is designed for the ECM-B3M motor and its 24-bit encoder. ECMA motors belong with the ASDA-B2 or ASDA-A2 drives.
