Safety Precautions

DriveProgramming User’s Manual (I622-E1)
Caution
Do not connect resistors to the terminals (PD/+1, P/+, N/-) directly.
Doing so might result in a small-scale fire, heat generation, or damage to the unit.
Install a stop motion device to ensure safety.
Not doing so might result in a minor injury.
(A holding brake is not a stop motion device designed to ensure safety.)
Be sure to use a specified type of braking resistor/regenerative braking unit.
In case of a braking resistor, install a thermal relay that monitors the temperature of the resistor.
Not doing so might result in a moderate burn due to the heat generated in the braking resis-
tor/regenerative braking unit.
Configure a sequence that enables the inverter power to turn off when unusual over eating is
detected in the braking resistor/regenerative braking unit.
The inverter has high voltage parts inside which, if short-circuited, might cause damage to itself
or other property. Place covers on the openings or take other precautions to make sure that no
metal objects such as cutting bits or lead wire scraps go inside when installing and wiring.
Take safety precautions such as setting up a molded-case circuit breaker (MCCB) that
matches the inverter capacity on the power supply side.
Not doing so might result in damage to property due to the short circuit of the load.
Do not dismantle, repair or modify the product.
Doing so may result in an injury.
If a parameter is set incorrectly when starting up, adjusting, maintaining, or replacing, an unex-
pected operation may occur.
If the DriveProgramming stops during multi-function output, the output status is held. Take
safety precautions such as stopping peripheral devices.
