605 Series Frequency Inverter
AUTOTUNE
This is an automated sequence by which the
Inverter can identify the motor parameters
necessary for correct operation in the
Sensorless Vector Fluxing mode.
Refer to Chapter 4: “Operating the Inverter”
- Set-up using the Sensorless Vector
Fluxing Mode.
Functional Description
The Autotune sequence takes a maximum of 10 seconds to indentify four cirtical parameters:
1.
No-load rms line current
2.
Per-phase stator resistance
3.
Per-phase leakage inductance
4.
Per-phase mutual inductance
The value of 1 above is stored in the CURRENT FEEDBACK block. The values for 2, 3 & 4 are
stored in the VECTOR FLUXING block. Autotune will overwrite any previous entry made for
these parameters.
Autotune can only be initiated from the “stopped” condition. The function block cannot be
changed whilst the drive is running. When the test is complete, the stack is disabled and the
motor left to coast.

Parameter Descriptions
ENABLE
Range: FALSE / TRUE
Determines whether the Autotune sequence is operational or not. The Autotune sequence is
operational when set to TRUE.
MODE
Range: Enumerated - see below
If set to USER NO LOAD I, the known value (NO LOAD CALIB) is used from the
CURRENT FEEDBACK block. If set to CALC NO LOAD I, this block will calculate a value
for NO LOAD CALIB and update it in the CURRENT FEEDBACK block.
Enumerated Value
:
Mode
0 : USER NO LOAD I
1 : CALC NO LOAD I
ACTIVE
Range: FALSE / TRUE
This indicates the current state of the Autotune sequence. The Autotune sequence is operational
when displaying TRUE.
