5. Function Selection
·
When the retry function is selected, the inverter may restart automatically after tripping.
(Design the machine to ensure personal safety in the event of restart)
Accident may result.
· When the torque limiting function is selected, operating conditions may differ from preset conditions
(acceleration/deceleration time or speed). In this case, personal safety must be assured.
Accident may result.
·
If AUTO RESTART is selected in the restart mode after momentary power failure (function code F14), the
inverter restarts automatically starting the motor rotation when the power is re-supplied.
Accident may result.
· When auto tuning (function code H01) is started, the motor, machine or equipment starts and stops
repeatedly. Ensure safety before performing auto tuning.
Accident may result.
·
If the user set the function codes wrongly or without completely understanding this user’s manual, the
motor may rotate with a torque or at a speed not permitted for the machine.
Accident or injury may result.
· During pre-excitation, the speed adjuster does not function and the motor may be rotated by load
disturbance. When using pre-excitation, therefore, also use the machine brake.
Injury may result.
·
If improper data is set at the function code related with speed adjuster as in the case of setting high gain
abruptly, the motor may hunt.
Injury may result.
