times as well as the PID control [(
P) Proportional Gain
and/or the
(I) Integral Time (see STEP 11)
directly control the
system dynamic response.
The longer the acceleration and deceleration time, the slower the system response, and the
shorter time, the faster the response. An excessive amount of time can result in sluggish
system performance while too short of a time may result in system instability.
The starting values suggested by this guide normally result in good system performance for
the majority of fan and pump applications. If the values need to be adjusted, caution
should be exercised, and the changes should be in small increments to avoid system
instability.

Parameters
Bn-01 (Acceleration)
and
Bn-02 (Deceleration)
are
both
set at the factory for
10.0 seconds.
For fan and pump applications, the recommended starting values are
30
seconds.
To change these parameters, follow the keypad navigation procedure as shown
next.
