Settings For The Control Methods - YASKAWA varispeed G7 CIMR-G7B series 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
NO
Vector control (A1-02 = 2, 3, or 4)
V/f control?
A1-02=0 or 1)
YES
V/f
PG?
NO
(Default:
A1-02=0)
Set E1-03. Set E1-03, E2-04, and F1-01.
V/f default: 200V/50Hz(400V/50Hz)
V/f default: 200V/50Hz(400V/50Hz)
Motor cable over
50 m or heavy load possibly
causing motor to stall
or overload?
NO
Stationary autotuning for
line-to-line resistance only
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 2 control.
* 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 1 control (A1-02 = 2).
* 4. If the maximum output frequency is different from the base frequency, set the maximum output frequency (E1-04) after autotuning.
