Tuning procedure when L03 = "4: Tuning with motor stopped"
(1) Specify the rated speed (F03), base speed (F04), rated voltage (F05), control mode (F42), no. of
poles (P01), rated capacity (P02), rated current (P03), %R1 (P07), %X (P08), pulse encoder
selection (L01),
resolution (L02), ASR P constant at high speed (L36) and ASR P constant at
low speed (L38) to match the motor and pulse encoder specifications.
(2) Set function code L03 to "4". When a run command is set, tuning starts.
After tuning, the tuning result is written into L04 data. After tuning, the L03 data will be
automatically reset to 0.
(3) Enter run forward and run reverse commands to run the motor at the low speed at least one
rotation in the forward and reverse directions, respectively. (Note 1)
(4) Turn the power off and then turn it on again to confirm that the motor runs normally. (Note 2)
Note 1:
If the motor fails to run normally, the A and B phases of the pulse encoder may be
mistakenly connected in wiring. Once shut down the power and correct the wiring of the A and B
phases. After parameter-tuning of the motor, do tuning again with the procedure above.
Note 2:
If the motor fails to run normally, the wiring of the magnetic pole position detection signals
may be wrong. Correct the wiring.
For details, refer to the instruction manual of the corresponding option card.
L05
ACR P constant
L06
ACR I constant
When a synchronous and induction motor is used, P constant and I constant of ACR (Automatic
Current Regulator) are set by parameters L05 and L06 respectively.
- Data setting range (L05): 0.0 to 15.0
- Data setting range (L06): 0.01 to 5.00 (ms)
L07
Automatic pole tuning selection
The automatic magnetic pole position tuning operates before it begins to drive when the magnetic
pole position is unknown due to power shutdown or other causes.
For instance, the magnetic pole position is unknown immediately after turning ON the power supply
when a synchronous motor is driven by using the encoder of an ABZ type encoder (L01=1).
Therefore, before the first operation after power ON the magnetic pole position tuning is
automatically performed. After completing successfully the pole tuning, it begins to drive. In
second operation or following, because the magnetic pole position has been correctly detected, the
magnetic pole position tuning is not done.
Data for L07
Function
0
The automatic magnetic pole position tuning doesn't operate.
The tuning is activated by input terminal (configured to
PPT
) operates in mode
L03=4, and operation changes according to of the setting of L99 bit1.
1 to 4
The automatic magnetic pole position tuning operates.
The tuning activated by input terminal (configured to
PPT
) operates according
to the mode set in L07. L99 bit1 setting is not effective.
Refer to the explanation of
PPT
for details.
When the function of the automatic magnetic pole position tuning is set to be effective,
L04 is not used as a magnetic pole position offset.
When the function of the automatic magnetic pole position tuning is set to be effective,
the used magnetic pole position offset in this mode is confirmed by function code M58.
