îš‹ Installation
Observe the following precautions when installing an Inverter.
îš„Installation in Enclosures
Install the Inverter in a clean location where it is not subjected to oil mist, dust, and other contaminants, or
install the Inverter in a completely enclosed panel. Provide cooling measures and sufficient panel space so that
the temperature surrounding the Inverter does not exceed the allowable temperature. Do not install the Inverter
on wood or other combustible materials.
îš„Installation Direction
Mount the Inverter vertically to a wall or other vertical surface.
îš‹ Settings
Observe the following precautions when making settings for an Inverter.
îš„Upper Limits
The maximum output frequency can be set up to 400Hz. Setting the output frequency too high can damage the
machine. So pay attention to the mechanical system and observe required limits for the output frequency.
îš„DC Injection Braking
If the DC Injection Braking Current or the Braking Time are set too high the motor can overheat what can
damage the motor
îš„Acceleration/Deceleration Times
The motor's acceleration and deceleration times are determined by the torque generated by the motor, the load
torque, and the load's inertial moment (GD
2
/4). If the stall prevention functions are activated during accelera-
tion or deceleration, it might be necessary to increase the acceleration or deceleration time.
To reduce the acceleration or deceleration times, increase the capacity of the motor and Inverter.
