*7  Brake resistor (FR-ABR, MRS type, MYS 

type) 
Install a thermal relay to prevent an 
overheat and burnout of the brake resistor. 
Always install a thermal relay when using 
a brake resistor whose capacity is 11K or 
higher. 
(The brake resistor can not be connected 
to the 0.1K and 0.2K.)

*8  It is not necessary when 

calibrating the indicator 
from the operation panel.

*9  Operation and parameter setting can be 

done from the parameter unit (FR-
PU07) and the enclosure surface 
operation panel (FR-PA07). 
(Use the option cable (FR-CB2     ).) 
RS-485 communication can be utilized 
from a personal computer and other 
devices.
