Yaskawa AC Drive Z1000 - Manual (Page 20)

Single-Phase Motor
Variable speed drives are not designed to operate with single phase motors. Using capacitors to start the motor causes excessive
current to flow and can damage drive components. A split-phase start or a repulsion start can burn out the starter coils because
the internal centrifugal switch is not activated. The drive is for use with three-phase motors only.
Motor with Brake
Take caution when using the drive to operate a motor with a built-in holding brake. If the brake is connected to the output side
of the drive, it may not release at start due to low voltage levels, so be sure to install a separate power supply for the motor
brake. Note that motors with built-in brakes tend to generate a fair amount of noise when running at low speeds.
u Drive Label Warning Example
Always heed the warning information listed in Figure i.2 in the position shown in Figure i.3 .
WARNING
Read manual before installing.
Wait 5 minutes for capacitor
discharge after disconnecting
power supply.
To conform to requirements,
make sure to ground the supply
neutral for 400V class.
After opening the manual switch
between the drive and motor,
please wait 5 minutes before
inspecting, performing
maintenance or wiring the drive.
Risk of electric shock.
Hot surfaces
Top and Side surfaces may
become hot. Do not touch.

AVERTISSMENT NPJT31470-1
Lire le manuel avant l'installation. Attendre 5 minutes après la coupure de l'alimentation, pour permettre la décharge des condensateurs. Pour répondre aux exigences , s assurer que le neutre soit relié à la terre, pour la série 400V. Après avoir déconnécte la protection entre le driver et le moteur, veuillez patienter 5 minutes avain d’effectuer une opération de montage ou de câblage du variateur.
Risque de décharge électrique.
Surfaces Chaudes Dessus et cotés du boitier Peuvent devenir chaud. Ne Pas toucher.
