YASKAWA Europe TOEP C710606 96A - AC Drive A1000 IP54 Wallmount - Quick Start Guide
Normal / Heavy Duty Selection (C6-01)
The drive supports two ratings, Normal Duty and Heavy Duty. Both have different output current ratings (refer to the
catalog or the Technical Manual). Set the Duty mode in accordance with the application.
Auto-Tuning (T1-
)
Auto-Tuning automatically sets up the motor data relevant drive parameters. Three different modes are supported.
Open Loop Vector Control
for PM
A1-02 = 5
Derated torque-load applications employing permanent magnet motors (SPM, IPM) and energy
savings.
Advanced Open Loop
Vector Control for PM
A1-02 = 6
This control mode can be used to operate an IPM motor for constant torque applications.
Closed Loop Vector
Control for PM
A1-02 = 7
• This mode can be used for high precision control of a PM motor in constant torque or variable
torque applications.
• A speed feedback signal is required.
<1> For explanations of these control modes, refer to the Technical Manual.

Application
Applications with a constant torque like extruders,
conveyors and cranes. High overload capability
might be needed.
Applications where the torque increases with the speed
like fans or pumps. High overload tolerance is normally
not needed.

Rotational Auto-
Tuning
T1-01 = 0
• Motor can be decoupled from the load and rotate freely
while Auto-Tuning is performed.
• Motor and load can not be decoupled but the motor load
is below 30%.
• Rotational Auto-Tuning gives the most accurate results,
and is therefore highly recommended if possible.
N/A

YES
YES
Stationary Auto-
Tuning 1
T1-01 = 1
• Motor and load can not be decoupled and the load is
higher than 30%.
• A motor test report listing motor data is not available.
• Automatically calculates motor parameters needed for
vector control.

YES
YES
Stationary Auto-
Tuning 2
T1-01 = 4
• Motor and load can not be decoupled and the load is
higher than 30%.
• A motor test report is available. Once the no-load current
and the rated slip have been entered, the drive calculates
and sets all other motor-related parameters.

YES
Stationary Auto-
Tuning for Line-to-
Line Resistance
T1-01 = 2
• The drive is used in V/f Control and other Auto-Tuning
selections not possible.
• Drive and motor capacities differ.
• Tunes the drive after the cable between the drive and
motor has been replaced with a cable over 50 m long.
Assumes Auto-Tuning has already been performed.
• Should not be used for any vector control modes unless
the motor cable has changed.
