Frequently Asked Questions
What does the E suffix mean on ASD-A2-0421-E?
EtherCAT model. EtherCAT fieldbus control, internal position (PR) control and electronic cam. No analog or pulse command inputs.
Which motor pairs with ASD-A2-0421-E?
ECMA motors with a 20-bit encoder, that is the C1, E1 and F1 prefixes, or a CA series absolute encoder motor, at the same power rating.
Does ASD-A2-0421-E support absolute encoder motors?
Yes. The ASDA-A2 works with the ECMA CA series absolute encoder motors, which keep position through a power cut with a battery fitted, so the machine does not need to re-home.
How is the ASDA-A2 different from the ASDA-B2?
The A2 is the high end family. It adds a 20-bit encoder instead of 17-bit, internal position control with an electronic cam, full closed loop with a second encoder, and fieldbus options including CANopen, DMCNET and EtherCAT.
