Preparation For Operation; Settings Of Data Before Operation; Automatic Tuning - GE VAT2000 Instruction Manual

3-4 Preparation for operation

Always confirm the following points before turning ON the power after completing wire.
(1) Remove the coupling and belt coupling the motor and machine, so that the machine can be run as a
single unit.
(2) Confirm that the power supply wire is correctly wired to the input terminals (L1, L2, L3).
(3) When using the 400V Series (X45K0S), confirm that the auxiliary power supply terminal (TBA) short
right terminals to match the power supply voltage.
For 380 to 400V : Link between 2-3 (factory setting)
For 415 to 480V : Link between 1-2
(4) Make sure that the power supply is within the tolerable range.
(5) Make sure that motor is connected with the correct phase order.
(6) Fix the motor with the specified method.
(7) Make sure that none of the terminal board screws are loose.
(8) Make sure that there is no short circuit state in the terminals caused by wire scraps, etc.
(9) Always correctly install the front cover and outer cover before turning the power ON.
(10) Assign an operator, and make sure that the operator operates the switches.

3-5 Settings of data before operation

(1) Turn ON the MCCB, and then turn ON the inverter power.
All LEDs will light momentarily on the indicator, and then
" ", "
The "LCL" and "Hz" LED will also light.
(2) Refer to Section 4-5, and confirm the rating parameters.

3-6 Automatic tuning

Automatic tuning measures the constants of the connected motor, and automatically adjusts the
parameters so that the system is used to their maximum performance.
VAT2000 automatic tuning can be carried out independently for each of the following types of control.
V/f control (constant torque)
V/f control (variable torque)
IM speed sensor-less vector control (C30-0 = 3)
IM vector control with speed sensor (C30-0 = 4)
(Note 1) All parameters belong blocks "B" and "C" -like parameter C30-0- are not displayed as default.
Check setting in parameter A05-2 prior set parameter C30-0
(Note 2) The PM motor control, does not have a specific Automatic tuning. Refer to 6-8 for details
