YASKAWA U1000 Quick Start Manual page 7

Observe proper electrostatic discharge procedures (ESD) when handling the drive and circuit boards. Failure to
comply may result in ESD damage to the drive circuitry.
Do not perform a withstand voltage test or megger test on any part of the drive.
Failure to comply could result in damage to the sensitive devices within the drive.
Do not operate damaged equipment.
Failure to comply could result in further damage to the equipment. Do not connect or operate any equipment with visible
damage or missing parts.
If a fuse is blown or a Ground Fault Circuit Interrupter (GFCI) is tripped, check the wiring and the selection of the
peripheral devices.
Check for short circuits or ground faults on the secondary side of fuses and GFCIs and check the wiring and the selection of
peripheral devices. Remove the cause of the problem and then turn the power supply off and on again. If the cause cannot
be identified, do not turn on the power supply or attempt to operate the equipment.
Do not restart the drive immediately operate the peripheral devices if a fuse is blown or a GFCI is tripped.
Check the wiring and the selection of peripheral devices to identify the cause. Contact your supplier before restarting the
drive or the peripheral devices if the cause cannot be identified.
Do not expose the drive to halogen group disinfectants.
Failure to comply may cause damage to the electrical components in the drive.
Do not pack the drive in wooden materials that have been fumigated or sterilized. Do not sterilize the entire package after
the product is packed.
n General Application Precautions
Selection
Drive Rated Output Current
Make sure that the motor rated current is less than the rated output current for the drive.
When 2 Seconds is Required for Momentary Power Loss Ride-Thru Time
Use the units listed below when continuing drive operation after the power is restored even after a momentary loss of power
of 2 seconds occurs:
• 200 V class Momentary Power Loss Ride-Thru unit: Model no. P0010
• 400 V class Momentary Power Loss Ride-Thru unit: Model no. P0020
Drive Start-Up Time
The drive requires 1.5 seconds to prepare for operation after the power is turned on. Be mindful of this delay when using an
external reference input.
Note: 1.5 seconds is the required time when no optional devices are used with the drive. When using an optional communication device, the time
required for the drive to be ready for operation will vary in accordance with the start up time of the communication card.
Selection of Power Supply Capacity
Use a power supply greater than the rated input capacity (kVA) of the drive. If the power supply is lower than the rated capacity
of the drive, the device will be unable to run the application properly and will trigger a fault.

Connection to Power Supply
The total impedance of the power supply and wiring for the rated current of the drive is %Z = 10% or more. Power voltage
distortion may occur when the impedance of the power supply is too large. When wiring over long distances, be sure to take
preventative measures such as using thick cables or series wiring to lower the impedance of wiring. Contact Yaskawa or your
Yaskawa agent for details.
