Settings For The Control Methods - Omron VARISPEED G7 Instruction Manual

Settings for the Control Methods

Autotuning methods depend on the control method set for the Inverter. Make the settings required by the con-
trol method.
Overview of Settings
Make the required settings in quick programming mode and autotuning mode according to the following flow-
chart.
START
V/f control?
YES
(A1-02 = 0 or 1)
V/f
PG?
NO
(Default: A1-02 = 0)
Set E1-03.
V/f default: 200 V/60 Hz(400 V/60 Hz)
Motor cable over
50 m or heavy load possibly
causing motor to stall
or overload?
NO
END
Note If the motor cable changes to 50 m or longer for the actual installation, perform stationary autotuning for the line-to-line resistance only on-site.
* 1. Use rotational autotuning to increase autotuning accuracy whenever it is okay for the motor to be operated. Always perform rotational autotuning when
using open-loop vector control 2.
* 2. If there is a reduction gear between the motor and PG, set the reduction ratio in F1-12 and F1-13.
* 3. The default setting of the Inverter is for open-loop vector control 1 (A1-02 = 2).
* 4. If the maximum output frequency and base frequency are different, set the maximum output frequency (E1-04) after autotuning.
NO
Vector (A1-02 = 2, 3, or 4)*3
YES
(A1-02 = 1)
Set E1-03, E2-04, and F1-01.
V/f default: 200 V/60 Hz(400 V/60 Hz)
YES
