Note that when you enable a particular function input for analog mode
operation, it has the same effect as pressing the equivalent function key on
your DCC cab. Tsunami’s function mapping settings will ultimately determine
which output or sound effect is activated by the enabled function. Assuming
you have not changed the default function mapping, then enabling the F0(f)
function in analog mode will not only turn on the headlight, but the dynamo
sound as well.
Analog Mode Motor Control Parameters
CV 63, Analog Mode Motor Start Voltage
CV 63 allows you to increase the voltage difference between when the
decoder first powers up and when the locomotive starts to move.
Normally, Tsunami will power up in Analog mode around 5 volts or so and
the engine will begin moving around 7.5 volts. Under certain circumstances
you may experience a condition where the decoder cycles back and forth
between start up sounds and locomotive movement. The problem is usually
due to a poorly regulated power pack output. The sudden increase in load
due to the motor starting causes the track voltage to droop which in turn
resets the sound decoder. By increasing the setting of CV 63, you can
adjust the decoder so that when the motor starts, the track voltage will be
sufficiently high so that any droop that occurs will not turn off or reset the
decoder.
CV 63 may be set to any value between 0 and 255 corresponding to tenths of
a volt. Thus, a setting of 23 adds 2.3 volts to Tsunami’s default start voltage
of 7.5 volts.
CV 64, Analog Mode Maximum Motor Voltage
CV 64 allows you to set the maximum average voltage that will be applied
to the motor when operating in analog mode. This is useful for limiting a
locomotive’s top speed as well as providing some margin of safety against
burning out a motor whose voltage rating may be lower than your power
pack’s maximum output
CV 64 may be set to any value between 0 and 255 corresponding to tenths
of a volt. A setting of 180 therefore sets the maximum average motor to 18.0
volts.
Caution: Tsunami only limits the average voltage to the motor. The peak
voltage applied to the motor will still be the same as the track voltage.
