2: Enabled (motor in rotate status)
Before the auto-tuning, be sure to enter the correct nameplate parameters of the controlled motor.
During the rotation setting, the asynchronous motor is in static state first. P03.07, P03.08, P03.09
parameter of the asynchronous motor will be automatically measured. And then the asynchronous motor
will turn into the rotation state, and the mutual inductive reactance P03.10 and no-load current (I
0
) P03.11
of the motor will be automatically measured. The measured parameter values will be automatically
written into P03.07~P03.11.
Auto-tuning steps:
1) Set the P07.07 torque increase of motor as 0.
2) Properly set the function code parameters of P03.00~P03.05 for motor.
3) Properly set P02.16 (upper limit frequency). The set value of P02.16 shall not be lower than the rated
frequency.
4) a. Set P03.25 to 1, select the static tuning
b. Set P03.25 to 2, select the rotation tuning (disconnect the motor shaft from the loads, and the motor
idles driven by the drive).
5) Press the ENTER/DATA key and the RUN key, and then the auto-tuning will be started.
6) When the running LED on the operation panel is off, it indicates that the auto-tuning is finished.
P03.25
will automatically be set to 0.
Note
1. When P03.25 is set as 2, if over-voltage or over-current occurs during the auto-tuning, properly increase
the acceleration/deceleration time (P02.13 and P02.14).
2. When P03.25 is set as 2 for rotation setting, disconnect the motor shaft from the loads. It is prohibited to
carry out rotation setting when the motor is connected to loads.
3. Before the auto-tuning, the motor shall be in static status, otherwise, the auto-tuning cannot be normally
conducted.
4. In certain situations (for instance, the motor cannot be disconnected from the loads) where it is
inconvenient to conduct rotation setting, or the user does not have high motor control performance
requirement, static tuning can be selected, or the tuning can be exempted. If the tuning is not performed, be
sure to enter the correct nameplate parameters of the motor.
5. If the auto-tuning fails, Er.TUN error will be reported.
4.3 Speed control parameters (Group P05)
0: Zero servo is disabled
1: Zero servo is always enabled
2: Zero servo is enabled under conditions (terminal enabled)
“Zero servo is enabled under conditions” means “zero servo enabled” can be realized through NO. 54
function of terminal Xi.
