Basic Drive Setup Adjustments - YASKAWA A1000 Series Quick Start Manual

4 Start-Up Programming & Operation

◆ Basic Drive Setup Adjustments

This section explains the basic settings required for initial drive operation. Checking these basic parameter settings
during start-up will help to ensure a successful drive start-up. If more information is required for parameters not listed in
this section, Refer to Parameter List on page 131
A1-02: Control Method Selection
■
Selects the Control Method (also referred to as the "control mode") the drive uses to operate the motor. If the drive is set
up to run two motors, then A1-02 determines the control mode for motor 1.
No.

<1> Regional default settings
Setting 2: Japan (Model code: CIMR-AA A) and Asia (Model code: CIMR-AT A)
Setting 0: China (Model code: CIMR-AB A)
Control Modes for Induction Motors (IM)
Setting 0: V/f Control for Induction Motors
V/f Control is for simple speed control and multiple motor applications with low demands to dynamic response or speed
accuracy. This control mode should be used when the motor parameters are unknown and Auto-Tuning cannot be
performed. The speed control range is 1:40.
Setting 1:V/f Control with PG Speed Feedback
For general-purpose applications that do not require high dynamic response but high speed accuracy. This mode should
be used if the motor parameters are unknown and Auto-Tuning cannot be performed. The speed control range is 1:40.
Setting 2: Open Loop Vector Control
For general, variable-speed applications with a speed control range of 1:120 that require precise speed control, quick
torque response, and high torque at low speed without using a speed feedback signal from the motor.
Setting 3: Closed Loop Vector Control
For general, variable-speed applications that requiring precise speed control down to zero speed, fast torque response, or
precise torque control. A speed feedback signal from the motor is required. The speed control range is up to 1:1500.
Control Modes for Permanent Magnet Motors (SPM or IPM)
Setting 5: Open Loop Vector Control for PM
Use this mode for variable torque applications and take advantage of the energy saving capabilities of a PM motor. Using
this mode, the drive can control an SPM or IPM motor with a speed range of 1:20.
Setting 6: Advanced Open Loop Vector Control for PM
This control mode can be used to operate an IPM motor for constant torque applications. Using High Frequency
Injection, a speed control range as high as 1:100 is possible.
Setting 7: Closed Loop Vector Control for PM
This mode can be used for high precision control of a PM motor in constant torque or variable torque applications. The
speed control range reaches 1:1500. A speed feedback signal is required.
A1-03: Initialize Parameters
■
Resets parameters back to the original default values. After initialization, the setting for A1-03 automatically returns to 0.
No.
A1-03
Setting 1110: User Initialize
Drive parameters are reset to values selected by the user as User Settings. User Settings are stored when parameter o2-03
is set to "1: Set defaults".
