1.3 SPECIFICATIONS:
This section contains the specifications for the brushless trapezoidal, sine/resolver and two or three
phase input current mode D.C. Servo Amplifiers. These specifications also include power supplies for the
amplifiers.
NOTE: All data in this section is based on the following ambient conditions: 120

maximum. Forced air cooling.
1.3.1 STAND ALONE ONE AXIS AMPLIFIER:
The stand alone one axis amplifier contains a single amplifier module, a DC power supply, a cooling
fan, fusing and shunt regulator in a sheet metal enclosure. The shunt regulator within the DC power
supply has a 50W internal load resistor bank which bleeds off excess DC Buss voltage when decelerating
a large load inertia. An external shunt regulator resistor can be connected (Consult with factory).
NOTE: Customer must specify the input AC voltage (105-120VAC/205-250VAC) when ordering (see
chapter 3: model numbering), so that the proper fan can be installed.
