SW1 determines the lead lag compensation networks, and is usually only modified to
achieve stability on high inertia loads.
SW2 is used to alter the operation of the R-D converter and is preset to the 12-bit mode.
This switch setting is only altered to achieve higher line density simulated encoder
selections or higher TAC gradients.
SW3 is used to alter the TAC gradient and works in conjunction with SW1 to achieve
stability on high inertia loads.
S2 switches 1-2 are used to determine the commutation of motors and are set for 6-pole
operation. When S2 switch 3 is ON (default), torque linearization to sine wave motors is
provided. When S2 switch 3 is OFF, torque linearization is not provided; this is typical for
trapezoid wound motors. S2 switch 4 can be used to invert the fault output to be normally
ON instead of OFF.
S3 is available to configure the operation of the I/O.
S4 is available to select the simulated encoder line density. The default setting is 1024
lines.
