Frequently Asked Questions
Which motor pairs with ASD-B2-0121-B?
It pairs with Delta ECMA motors carrying a 17-bit encoder, that is the C2, E2, F2 and G2 prefixes, at the same power rating. We can quote the drive and motor as a matched set with the power and encoder cables.
Can ASD-B2-0121-B run on single-phase 220 V?
Yes. The 21 in the model code means it accepts 200 to 255 V on either single-phase or three-phase.
Does ASD-B2-0121-B support CANopen or EtherCAT?
No. The ASDA-B2 has RS-485 Modbus only. If you need CANopen use the ASDA-A2 M model, and for EtherCAT use the ASDA-A2 E model or the ASDA-B3 E model.
What cables do I need with ASD-B2-0121-B?
A motor power cable and an encoder cable, both sized to the distance between the drive and the motor. Tell us the cable length you need and we will include them in the quotation.
