1 Safety Instructions and General Warnings
CAUTION
Burn Hazard
Do not touch the heatsink or braking resistor hardware until a powered-down cooling period has elapsed.
NOTICE
Equipment Hazard
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 unit.
Failure to comply could result in damage to the sensitive devices within the drive. Use power off resistance checks to
determine shortcircuits.
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.
Do not use unshielded cable for control wiring.
Failure to comply may cause electrical interference resulting in poor system performance. Use shielded twisted-pair
wires and ground the shield to the ground terminal of the drive.
Only connect recommended devices to the drives braking transistor terminals.
Failure to comply could result in damage to the drive or braking circuit.
Carefully review instruction manual TOBP C720600 0 when connecting a braking option to the drive.
Do not modify the drive circuitry.
Failure to comply could result in damage to the drive and will void warranty.
YASKAWA is not responsible for modification of the product made by the user. This product must not be modified.
Check all the wiring to ensure that all connections are correct after installing the drive and connecting other
devices.
Failure to comply could result in damage to the drive.
Improper application of devices on drive output circuits can damage the drive
Do not connect unapproved LC or RC interference suppression filters, capacitors, ground fault circuits, or overvoltage
protection devices to the drive.
Check the motor rotation and elevator movement direction prior to starting up the drive.
The drive puts out voltage in phase sequence U-V-W with an Up command. Make sure the elevator moves up if the
motor is supplied with this phase sequence.
Always remove the ropes when performing Rotational Auto-Tuning.
During Rotational Auto-Tuning the drive turns the motor for a certain time. Not removing the ropes might result in
damage to the equipment.
When using a PM motor, make sure the motor can handle the maximum current delivered by the drive.
Operating the motor with too high current may result in demagnetization.
