TOSHIBA
An input reactor, radio noise reduction filter, braking resistor, and operation
panel extension cable are all available as externally installed options.
15.1 Input Reactor
This device is installed to improve the power factor, or suppress the harmonic
currents and line surges. This device is also recommended when the drive is
connected to a large capacity power supply (over 200 KVA), or when any distortion
source such as large power thyristors or arc furnaces are connected to the same
power grid, or a large capacity inverter is connected to the grid.
15.2 Radio Noise Reduction Filter
This device is installed to block radio frequency harmonics that the inverter
radiates outward to sensitive equipment, causing humor static on remote devices,
such as radios, portable telephones, or other nearby communication devices.
15.3 Braking Resistor
This device is used whenever very rapid deceleration of a load is required, or
to increase the braking torque during deceleration of a large inertia load.
The braking resistor can become very hot during repeated braking applications.
Be sure it is properly ventilated, and do not locate this device near any
combustible material.
15.4 Connection Cabie
Use this connection cable for an extension from the drive unit to the touchpad
operation panel, if it is ever required to mount these two devices separately
from each other.
