Frequently Asked Questions
Does ECMA-C20604SS have a holding brake?
Yes. The S in the shaft option field means a 24 V DC holding brake is fitted. The brake holds the load when power is removed; it is not a dynamic stopping brake.
Which drive do I use with ECMA-C20604SS?
Delta ASDA-B2, ASDA-A2 at the same power rating. We normally supply the drive, the motor, the power cable and the encoder cable together as a matched set.
What does the part number ECMA-C20604SS mean?
Reading the code: the letter after ECMA sets the voltage and rated speed, the next digit is the encoder type, the next two digits are the flange size in millimetres, the next two are the power, then the shaft and brake option letter, then the shaft diameter code.
What is the shaft size on ECMA-C20604SS?
The shaft is 14 mm h6 keyway with tapped hole.
