Product Description

The DM-100 is a model of the Reliance Electric BRU-500 series of Servo Drives. It could be also sold under the Baldor Reliance and ABB production lines depending on when it was created.  It is no longer being supported by any of these companies and is a legacy series drive. AX Control attempts to keep it stocked.

The DM-100 has a 125/375 VDC bus voltage or a value of 325VDCs with a 230VAC input. It has a continuous and peak amperage of 50A and 100A respectively. It has a wattage loss of 275W maximum. This drive’s purpose is to provide an Electro-Craft motor with the necessary power and control to function. It is suggested to use an S-Series, F-series, or I-series motor with this drive. The motors that this includes are the S-6200, S-8350, F-6200, F-6300, or I-5300 TEAO. TEAO stands for "totally enclosed air over."

The DM-100 has 4 LED indicators on its faceplate. They are labeled 1-4 and show a user that either the drive is functioning as it should be or that it has errors present. There is a set of connection ports that are labeled P1 Communication, P2 I/O, P3 Encoder Off, P4 Encoder In, P5 Monitor, P6 Serial. This drive has two exposed fans on its bottom. It should be mounted vertically onto a totally flat surface like a panel or backplane. Nothing should be mounted directly above, below, or next to it to keep the drive components from overheating. It has brackets that can be used along with a set of bolts and washers to mount it to the panel.
