About the 9106-0081
The 9106-0081 is a 15 Amp Electro-Craft Servo Amplifier made by Reliance Electric for their BSA series. This servo amplifier may have also been mass-produced and sold by ABB and/or Baldor Reliance depending on what years it was actually in production. The alternate part number for this device is BSA-15.
The 9106-0081 is 108-132 VAC RMS, single-phase, 50/60 Hz with an internal DC bus of 152-187 VDCS or 170 VDCs with a 120 VAC input. It has a continuous drive current of 5 amps, a peak drive current of 15 amps, and a continuous shunt power of 50-1000 watts. It can be operated in temperatures between 0 to +50 degrees Celsius and a 5 to 95% non-condensing humidity. It also has a 22 K ohms VCS input impedance. It weighs right around 5.4 kg. This amplifier can be paired with an LD-2003, S-2005, or an S-3007 type motor.
The LED indicators on the 9106-0081 have the ability to detect the following faults. LEDs 1, 2, and 3 will glow in different patterns to alter the user to different faults. These faults include Bus over-voltage, output over-current, drive over-temp, motor over-temp, logic supply fault, and AC line loss. When none of these LEDs are glowing, it indicates that the drive is okay. This module also has three RS-232 connections. One is a female connection while two are male. The two male connections are for the encoder while the female is for the controller. There is also a terminal strip on the top of the faceplate. It has 6 total terminals.
