Finishing tuning
Stop the start command to finish tuning.
When the polarity reversible operation is not required, set
Pr.73
back to the previous value.
NOTE
• To finish tuning forcibly, perform any of the following:
Set "8" in
Pr.1219
.
Turn OFF the start signal.
Inverter reset
Turn ON the MRS signal.
Procedure of tension PI gain tuning (during operation)
POINT
POINT
• Perform tension PI gain tuning during stopping first, and then perform tension PI gain tuning during operation as required.
1
Parameter setting
Set the following parameter.
2
Starting operation
Start the inverter operation.
3
Starting tuning
Set "1" in
Pr.1219 Tension PI gain tuning start/status
or turn ON the Tension PI gain tuning start / forced end
(PGT) signal during operation to start tuning. To input the PGT signal, set "81" in any of
Pr.178 to Pr.189 (input
terminal function selection)
to assign the function.
The inverter returns to the normal operation after the tuning is completed. As a proof of normal completion, the
Pr.1219
setting changes to "13".
NOTE
• To finish tuning forcibly, perform any of the following:
Set "8" in
Pr.1219
.
Turn OFF the Tension PI gain tuning start / forced end (PGT) signal.
Turn OFF the start signal.
Inverter reset
Turn ON the MRS signal.
• If "1" is already set in
Pr.1219
or the PGT signal is ON when the power is supplied to the inverter, tuning does not start by
starting the start command.
CAUTION
When tension PI gain tuning is started, the motor is automatically started and the dancer roll starts
moving. If a too large value is set in Pr.1222 under dancer feedback speed control, the dancer roll
may hit against the system and result in damage.
