TOEPYAIH6B01A HV600 AC Drive Narrow Bypass Installation & Startup
Note:
Better performance is possible when you use a motor with a rated voltage that is less than the input supply voltage (by 20 V for 208/240 V
models or by 40 V for 480 V models). This is very important when operating the motor at more than 90% of base speed, where high torque
precision is necessary. If the input power supply is equal to the motor rated voltage, the drive output voltage will not be sufficient, and
performance will decrease.

on the keypad to cancel Auto-Tuning.
•
If a Safe Disable input signal is input to the bypass during Auto-Tuning, Auto-Tuning measurements will not
complete successfully. If this occurs, cancel the Auto-Tuning, then do it again.

is assigned functions the same as during usual operation.
WARNING!
Crush Hazard. Wire a sequence that will not let a multi-function output terminal open the holding brake during
Stationary Auto-Tuning. If the holding brake is open during Stationary Auto-Tuning, it can cause serious injury or death.
WARNING!
Sudden Movement Hazard. Before you do Rotational Auto-Tuning, disconnect the load from the motor. The load can
move suddenly and cause serious injury or death.
WARNING!
Injury to Personnel. Rotational Auto-Tuning rotates the motor at 50% or more of the motor rated frequency. Make sure
that there are no issues related to safety in the area around the drive and motor. Increased motor frequency can cause serious
injury or death.
WARNING!
Electrical Shock Hazard. During Auto-Tuning, the motor will receive high voltage when the motor is stopped. Do not
touch the motor until Auto-Tuning is complete. If you touch a motor that is energized, it can cause serious injury or death.

Precautions before Rotational Auto-Tuning
WARNING!
Electrical Shock Hazard. During Auto-Tuning, the motor will receive high voltage when the motor is stopped. Do not
touch the motor until Auto-Tuning is complete. If you touch a motor that is energized, it can cause serious injury or death.
•
Before you do Rotational Auto-Tuning, to prevent drive malfunction, uncouple the motor from the load. If you do
Rotational Auto-Tuning with the motor connected to a load that is more than 30% of the motor duty rating, the
bypass will not correctly calculate the motor parameters and the motor can operate incorrectly.
•
When the load is 30% or less of the motor duty rating, you can do Auto-Tuning with the motor connected to a load.
•
Make sure that the motor magnetic brake is released.
•
Make sure that external force from the machine will not cause the motor to rotate.
■
Precautions before Stationary Auto-Tuning
•
Make sure that the motor magnetic brake is not open.
•
Make sure that external force from the machine will not cause the motor to rotate.
WARNING!
Electrical Shock Hazard. During Auto-Tuning, the motor will receive high voltage when the motor is stopped. Do not
touch the motor until Auto-Tuning is complete. If you touch a motor that is energized, it can cause serious injury or death.
■
Precautions before Stationary Auto-Tuning for Line-to-Line Resistance and Stator
Resistance Auto-Tuning
In V/f control, when the motor cable is 50 meters (164 feet) or longer, do Stationary Auto-Tuning for Line-to-Line
Resistance.
WARNING!
Electrical Shock Hazard. During Auto-Tuning, the motor will receive high voltage when the motor is stopped. Do not
touch the motor until Auto-Tuning is complete. If you touch a motor that is energized, it can cause serious injury or death.
