Setting procedure of PM sensorless vector control
(speed control)
This inverter is set for an induction motor in the initial setting. Follow the following procedure to change the setting for the PM
sensorless vector control.
Operating procedure
1.
Set the applied motor (
Pr.9, Pr.71, Pr.80, Pr.81, Pr.83, and Pr.84
). (Refer to
,
Set "8093" (IPM motor) or "9093" (SPM motor) in
Pr.71 Applied motor
. Set
Pr.9 Rated motor current, Pr.80 Motor
capacity, Pr.81 Number of motor poles, Pr.83 Rated motor voltage, and Pr.84 Rated motor frequency
according to the motor specifications. (Operation does not start when the setting values of
Pr.80 and Pr.81
are
"9999" (initial value).)
2.
Select the PM sensorless vector control (
Pr.800
). (Refer to
.)
The PM LED on the operation panel turns ON when the PM sensorless vector control is set by setting
Pr.800
= "10".
3.
Perform the offline auto tuning for a PM motor (
Pr.96
). (Refer to
Set "1" (offline auto tuning without rotating motor) in
Pr.96
, and perform tuning.
4.
Configure the initial setting for the PM sensorless vector control using
Pr.998
. (Refer to
.)
When the setting for the PM motor is selected in
Pr.998 PM parameter initialization
, all the parameters required
for PM sensorless vector control are automatically set.
5.
Set parameters such as the acceleration/deceleration time and multi-speed setting.
Set parameters such as the acceleration/deceleration time and multi-speed setting as required.
6.
Set the operation command. (Refer to
.)
Select the start command and speed command.
7.
Perform the test operation.
NOTE
• To change to the PM sensorless vector control, perform PM parameter initialization after offline auto tuning. If parameter
initialization is performed after setting other parameters, some of those parameters are initialized too. (Refer to
for
the parameters that are initialized.)
• To use a motor capacity that is one rank lower than the inverter capacity, set
Pr.80 Motor capacity
before performing PM
parameter initialization.
• The carrier frequency is limited during PM sensorless vector control. (Refer to
• The protective function may be activated due to insufficient torque in the low-speed range of 10% of the rated motor frequency
or lower. The toque limit is not activated.
• During PM sensorless vector control, the RUN signal is output about 100 ms after turning ON the start command (STF, STR).
The delay is due to the magnetic pole detection.
