For details, see section 4.2.2 "Setting and
Auto-tuning of Motor Parameters".
4. Perform motor trial
running.
F0-08 = 5.00 Hz Trial running frequency
Start trial running in operation panel
control and monitor whether the output
current is normal. For details, see section
4.2.3 "Trial Running Check".
Note
Ensure that the overow valve is opened completely so that there is no load during trial running.
4.2.2 Setting and Auto-tuning of Motor Parameters
■
Parameter Setting
The IS580 controls the servo pump in closed-loop vector control (CLVC) mode. This mode requires accurate motor
parameters. To guarantee good driving performance and running efficiency, set the motor parameters strictly
according to the nameplate of the standard adaptable motor. The following table lists the parameters to be set.
Function Code Parameter Name Description
F1-00 Motor type
0: Common asynchronous motor
1: Variable-frequency asynchronous motor
2: PMSM
F1-01 to F1-05
Rated motor power
Rated motor voltage
Rated motor current
Rated motor frequency
Rated motor rotational speed

1: Obtain the value directly from the manual provided by the
motor manufacturer.
2: Obtain the value by means of dynamic auto-tuning if the value
cannot be obtained from the motor manufacturer.
