About the DM-20
The DM-20 is a brushless servo drive that is in control of providing system power and control that is typically needed to run an F-Series or S-Series Electro-Craft Motor. The user has the ability to separately purchase several suggested motors that can be paired with this drive. These motors are F-4030, S-4030, and S-3016. This drive is 120/240 VAC and has:
- a peak amperage of 20A
- a continuous amp rating of 10A
- a 141-340 DC bus that has the option of being 325 VDC when using a 230 VAC input
- a command signal range between +/-10 VDCs and 13.3k ohms impedance
- a 100W +dissipative shunt max power loss
- a normal power loss range typically around ½ the maximum amount
- a 50W continuous shunt and a 4.5 kW peak power shunt
There are four LED indicators on the faceplate of the DM-20. They are red and green and labeled numerically 1-4. There is a terminal strip that is located on the bottom left side of the faceplate. It has a very small green Ready LED indicator slightly below it. On the right side of the faceplate, there are six other connectors.
