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 111 .
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.
