== Overview ==

Brushed DC servo amplifiers, supports current mode or tachometer feedback for velocity mode. The settings are set using resistors and capacitors across SIP sockets, though sometimes they are soldered to a monolithic PCB that is mated to the sockets instead.

== Model Numbers ==

Page 7 in the "MAN_SSA_UG_EN_0698.pdf" (SSA Series manual) describes the model number scheme ("type designation").

== Wiring Diagram ==

In the "MAN_SSA_UG_EN_0698.pdf" (SSA Series manual):

Page 14 shows the block diagram of the amplifier, showing where the external resistors/capacitors are being inserted into the circuitry.

Page 15 shows the physical layout of the user configurable resistors/capacitors, the potentiometers, and the connectors.

Page 16-17 describe the connector pinouts. More detailed information is in subsequent pages.

== Resistor/Capacitor Settings ==
