*1 Vector control is not applicable. When using an encoder in explosive
area, use an explosion-proof encoder.
*2 High-duty brake resistor (FR-ABR) can be used for 22K or less.
To use, change the following parameters.
(Applies to the products manufactured in September 2008 or later.)
• Set [Pr. 30 = 1].
• Set [Pr. 70] as follow.
7.5K or less ......10%
11K or more .....6%
*3 Motors with frame number 250 or higher can be used in combination
with MT-BR.
*4 Explosion-proof test by the Ministry of Health, Labour and Welfare is
separately required. For that purpose, inverter needs to be a special
model.
