8.0 LocoMotion CVs

8.1 Acceleration and Deceleration Rates

Acceleration and Deceleration rates are used to simulate operating a real train

with your throttle.

8.1.1 Acceleration Rate: CV03

Acceleration is the rate at which the decoder increases from one speed step to

the next in response to a new command to increase speed. CV03, acceleration,

lets you simulate train weight or inertia. The range of values for acceleration is

000 to 031. Setting CV03 to a value of 00 generates an immediate response to

a new command to increase speed. As you increase the CV value programmed

into CV03, the rate of speed step change is approximately 1/10 second per

increment in acceleration value.

For example, a value of 01 programmed to CV03 will cause the decoder to

change at 1/10 second per speed step (using the 28 speed step range). This

means that it would take approximately 2.8 seconds for the loco to go from

stopped to full speed if you command the loco to go immediately to full speed.

8.1.2 Deceleration Rate: CV04

Deceleration is the rate at which the decoder decreases from one speed step to

the next in response to a new command to decrease speed. CV04, deceleration,

lets you simulate locomotive braking action. The range of values for CV04,

deceleration, is 000 to 031. A value of 00 causes an immediate response to a

new command to decrease speed. As you increase the CV value programmed

into CV04, the rate of speed step change is approximately 1/10 second per

increment in deceleration value.

For example a value of 01 programmed to CV04 causes the decoder to change

at 1/10 second per speed step (using the 28 speed step range). This means that

it would take 2.8 seconds to decelerate from full speed to stop if you com-

manded the loco to go immediately to stop when it was moving at full speed.
