Accel/Decel Selection
The Accel/Decel rate can be obtained by a variety of methods. The
default rate is determined by P039 [Accel Time 1] and P040 [Decel Time
1]. Alternative Accel/Decel rates can be made through digital inputs,
RS485 (DSI) communications and/or parameters. See the chart below
for the override priority.
