Installation
Observe
the following precautions when installing an Inverter.
n
Installation in Enclosures
Either
install the Inverter in a clean location not subject to oil mist, airborne matter, dust, and other contami-
nants,
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 go beyond the allowable temperature. Do not
install
the Inverter on wood or other combustible materials.
n
Installation Direction
Mount
the Inverter vertically to a wall or other horizontal surface.

Settings
Observe
the following precautions when making settings for an Inverter.
n
Upper Limits
The
Digital Operator can be used to set high-speed operation up to a maximum of 400 Hz (depends on the car-
rier
frequency). Incorrect settings can be dangerous. Use the maximum frequency setting functions to set
upper
limits. (The maximum output frequency is factory-set to 60 Hz.)
n
DC Injection Braking
The
motor can overheat if the DC injection braking voltage or braking time is set to a large value.
n
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, increase the acceleration or deceleration time. The stall prevention functions will increase
the
acceleration or deceleration time by the amount of time the stall prevention function is active.
To
reduce the acceleration or deceleration times, increase the capacity of the motor and Inverter.
