tion terminals. For multi-speed control, the acceleration time / deceleration time, ro‐
tation direction for each stage can be configured via parameters [E2.35], [E2.37],
[E2.39], [E2.41], [E2.43], [E2.45], [E2.47] and [E2.49].
1. Only 5 external terminals digital inputs are available for the frequen‐
cy converter, so please properly assign these 5 terminals when ac‐
celeration / deceleration time terminal and FWD / REV terminal are
needed.
2. [b1.00] / [b1.16] frequency setting source should be set to 6 before
multi-speed control is activated.
3. The rotation direction of every stage depends not only on stage ac‐
tion selection but also on RUN command source, see more details in
fig. 8-43 "Rotation direction and Acc. / Dec. for multi-speed / Simple
PLC" on page
4. If the set frequency of next stage is lower than current stage, it will
decelerate to the next stage with the deceleration time of current
stage; If the set frequency of next stage is higher than current stage,
it will accelerate to the next stage with the acceleration time of next
stage.
● Simple PLC control
Simple PLC is an automatic running mode according to the preset acceleration / de‐
celeration time, running frequency, running time and rotation direction. One cycle of
simple PLC control is shown in the figure below.
