Dancer roller position detection signal adjustment
When terminal 4 input is voltage input, 0V is the minimum position and 5V(10V) is the maximum position. When current is
input, 4mA is the minimum position and 20mA is the maximum position. (initial value) When 0 to 7V is output from the
potentiometer, it is necessary to calibrate
C7 (Pr .905)
at 7V.
(Example) Control at a dancer center position using a 0 to 7V potentiometer
1) After changing the current/voltage input switch to "V", set "2" in
Pr. 267
to change terminal 4 input to voltage input.
2) Input 0V to across terminal 4 and 5 to calibrate
C6 (Pr. 904)
. (% display displayed at analog calibration is independent
to % of the feed back value.)
3) By inputting 7V to across terminal 4 to 5, calibrate
C7(Pr. 905)
(% display displayed at analog calibration is
independent to % of the feed back value.)
4) Set 50% in
Pr.133
.
NOTE
When the
Pr. 267
setting was changed, check the voltage/current input switch setting. Different setting may cause a
fault, failure or malfunction. (

REMARKS
PID control stops when RH, RM, RL, and REX signals (for multi-speed operation) or JOG signal is input during normal PID
control. However, PID control continues when those signals are input during dancer control since these are treated as speed
commands.
During dancer control,
Second acceleration/deceleration time
of
Pr.44
and
Pr.45
are the parameters for acceleration/deceleration
time setting to the main speed command source. These do not function as the second function.
When switchover mode is set with "6" in
Pr. 79
, dancer control (PID control) is invalid.
Speed command to terminal 4 by turning AU signal ON is invalid during dancer control.
Acceleration/deceleration of the main speed command is the same operation as when frequency command is increased/
decreased by analog input.
Therefore, SU signal remains ON even if the starting signal is turned ON/OFF.(always in the constant speed state)
The DC brake operation starting frequency when turning OFF the starting signal is not
Pr. 10
but a smaller value of either
Pr. 13
or 0.5Hz.
The set frequency monitor is always variable as "main speed PID control".
The main speed setting frequency accelerates for the acceleration/deceleration time set in
Pr. 44
and
Pr. 45
and the output
frequency accelerates/decelerates for the acceleration/deceleration time set in
Pr. 7
and
Pr. 8
. Therefore, when the set time of
Pr. 7
and
Pr. 8
is longer than
Pr. 44
and
Pr. 45
, the output frequency accelerates/decelerates for the acceleration/deceleration
time set in
Pr. 7
and
Pr. 8
.
For the integral term limit, a smaller value of either the PID manipulated variable (%) value converted from the linear
interpolated
Pr. 1 Maximum frequency
with
Pr. 902
and
Pr. 903
, or 100% is used for limit.
Although the output frequency is limited by the minimum frequency, operation limit of the integral term is not performed.
