P129: Vector Control Select - Panasonic VF100 Instruction Manual

P129£º Vector control select
When large starting torque or sufficient torque is required at low speed, this function is valid in the
case that the load changes sharply.
It's not applicable to the load that minor rotation may lead to problems at low speed.
¡ö When using vector control mode, the specifications below should be met.
•E The motor is general-purpose cage type or induction motor.
•E The motor capacity is "the same as" or "one level lower than" the inverter capacity,
and it is 0.4kW or more.
•E One level lower refers to the motor with the same rated value as that of the inverter capacity.
Other motor capacity accords to the rated value that is close to host one.
•E Motor polarity is 2, 4, or 6 poles.
•E Signal-unit operation. (One motor is applied in one inverter.)
•E Max. wiring length between inverter and motor is 30m or less.
•E Carrier frequency is 2.5 kHz or more.
Under other conditions, good operating characteristics may not be achieved.
¡ö In the vector control mode, carrier frequency may automatically change in the area where
output frequency is relatively low.
[Setting procedure when vector control is selected]
1) Control method select : Vector control is selected. (P129 is set to "1".)
2) Motor capacity setting : Motor capacity in use is set to "P130: Motor capacity". (0.2~3.7kW)
Motor capacity and inverter capacity are the same at factory setting.
If motor capacity and inverter capacity are the same, setting is not required.
3) Motor polarity setting : Motor polarity in use is set to "P130: No. of motor poles". (2, 4, 6 poles)
Motor polarity is set to 4 poles at factory setting.
If motor polarity is set to 4 poles, setting is not required.
4) Operation on trial : If the required motor characteristics are achieved, setting is completed till now.
(Operation under motor constant recommended by our company.)
If the required motor characteristics are not achieved, the setting below will be applied.
5) Motor constant setting : When motor constant is known beforehand,
"P133: Voltage compensation constant" setting
"P134: Slip compensation frequency" setting
When motor constant is unknown beforehand, automatic tuning is applied.
"P132: Measurement function of motor constant" is set to "1",
and measure voltage compensation constant.
"P132: Measurement function of motor constant" is set to "2",
and measure the slip compensation frequency.
6) Operation on trial : If the required motor characteristics are achieved, the setting is completed till now.
After motor constant is set with P133 and P134, the required motor characteristics are still not
achieved, automatic tuning will be applied.
