OPERATION
4.3.3 Input terminal function selecttion (Pr.2, Pr.3)
Relationship between the setting value and terminal function
* If BUE signal (brake operation enable) is not assigned, brake operation is always allows.
Use these parameters to select/change the input terminal functions.

Setting Signal Function Description
0 RES Brake unit reset
Used to reset alarm output provided when
protective circuit is activated.
Turn on the RES signal for more than 0.1s,
then turn it off.
(Reset operation is made both at a normal
operation and an alarm.)
1 BUE
*
Brake operation
permission signal
Input operation permission signal from
outside. Turning off the signal shuts off
power and turning on the signal allows
brake operation.
When other regeneration units such as a
power regeneration converter are installed,
use this signal to allow or limit operation of
the brake unit.
2 OHB
Brake resistor
overheat
(NC contact)
Input contact when using an external
thermal relay to protect resistor from
overheat, etc.
Turning off the signal results in resistor
overheat alarm (OHT).
Available when the FR-BR is connected.
3 OHA
Brake resistor
overheat
(NO contact)
Input contact when using an external
thermal relay to protect resistor from
overheat, etc.
Turning on the signal results in resistor
overheat alarm (OHT).
Available when the MT-BR5 is connected.
