Application Notes - YASKAWA T1000V Technical Manual

Do not carry the drive by the front cover.
Failure to comply may result in minor or moderate injury from the main body of the drive falling.
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.
Never connect or disconnect the motor from the drive while the drive is outputting voltage.
Improper equipment sequencing could result in damage to the drive.
Do not perform a withstand voltage 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.
Install adequate branch circuit short circuit protection per applicable codes.
Failure to comply could result in damage to the drive.
The drive is suitable for circuits capable of delivering not more than 30,000 RMS symmetrical Amperes, 240 Vac
maximum (200 V Class) and 480 Vac maximum (400 V Class).
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.

Installing a Reactor
An AC or DC reactor can be used for the following:
• to suppress harmonic current.
• to smooth peak current that results from capacitor switching.
• when the power supply is above 600 kVA.
• when the drive is running from a power supply system with thyristor converters.
Note: A DC reactor is built in to 200 V and 400 V class models with a capacity of 22 kW and higher (HD rating).
Figure i.1
Drive Capacity
For specialized motors, make sure that the motor rated current is less than rated output current for the drive. When
running more than one motor in parallel from a single drive, the capacity of the drive should be larger than 1.1 times of
the total motor rated current.
