NOTE
• Normally, set
Pr.7 Acceleration time
and
Pr.8 Deceleration time
to "0 s". When the
Pr.7
and
Pr.8
settings are large, dancer
control response becomes slow during acceleration/deceleration.
• The
Pr.127 PID control automatic switchover frequency
setting is enabled. The larger setting value between
Pr.7
and
Pr.44
is used as the acceleration time during normal operation. For the deceleration time, the larger setting value between
Pr.8
and
Pr.45
is used. (For the details of
Pr.127
, refer to
.)
• If an automatic restart after instantaneous power failure is activated during dancer control, E.OC[] or E.OV[] is likely to occur.
In such case, disable the automatic restart after instantaneous power failure function (
Pr.57
= "9999").

Dancer control operation selection (Pr.128)
When
Pr.133
"9999", the
Pr.133
setting is valid.
• To enable dancer control, set "40 to 43" in
Pr.128 PID action selection
.
• Dancer control is enabled only when the PID control valid terminal (X14) signal turns ON when "14" is set in one of
Pr.178
to Pr.182 (Input terminal function selection)
and X14 signal is assigned.
When the X14 signal is not assigned, dancer control is enabled only by the
Pr.128
setting.
• Input the main speed command (External, PU, Communication). Dancer control is also supported by the main speed
command in all operation modes.
• Input the set point between the terminals 2 and 5 (the setting can be selected using
Pr.133
or
Pr.609
) and input the
measured value signal (dancer roll position detection signal) between the inverter terminals 4 and 5 (the setting can be
selected using
Pr.610
).
• The action of
Pr.129 PID action selection, Pr.130 PID integral time, Pr.131 PID upper limit, Pr.132 PID lower limit
and
Pr.134 PID differential time
is the same as PID control action. In the relationship between the control amount (%) and
frequency in PID control, 0% and 100% are equivalent to the frequencies set to
Pr.902
and
Pr.903
, respectively.

The main speed command differs according to each operation mode (External, PU, communication).
The output signal terminal to be used differs according to the
Pr.190 to Pr.196 (Output terminal function selection)
setting.
The input signal terminal to be used differs according to the
Pr.178 to Pr.189 (Input terminal function selection)
setting.
The AU signal need not be input.
