(3) Connection example
POINT
Connecting PR terminal of the brake unit to L terminal of the converter unit
results in a brake unit malfunction. Always connect the PR terminal of the
brake unit to the PR terminal of the resistor unit.
(a) Combination with FR-BR-(H) resistor unit
POINT
To use brake units with a parallel connection, use two sets of FR-BU2-(H)
brake unit. Combination with other brake unit results in alarm occurrence or
malfunction.
Always connect the master and slave terminals (MSG and SD) of the two
brake units.
Do not connect as shown below.

)
Note 1. For power supply specifications, refer to section 13.1.3.
2. Configure the circuit to turn OFF the forced stop (EM1) of the drive unit and the converter unit at the same time.
3. Always connect P
1 and P2 terminals (Factory-wired). When using the power factor improving DC reactor, refer to section 13.9.6.
4. Connect P/
and N/ terminals of the brake unit to a correct destination. Wrong connection results in the converter unit and
brake unit malfunction.
5. For the converter unit and the drive unit of 400V class, a stepdown transformer is required.
6. Contact rating: 1b contact, 110VAC_5A/220VAC_3A
Normal condition: TH1-TH2 is conducting. Abnormal condition: TH1-TH2 is not conducting.
7. Contact rating: 230VAC_0.3A/30VDC_0.3A
Normal condition: B-C is conducting/A-C is not conducting. Abnormal condition: B-C is not conducting/A-C is conducting.
8. Connect the thermal relay censor of the servo motor.
9. Do not connect more than one cable to each L
and L terminals of TE2-1 of the converter unit.
10. Always connect BUE and SD terminals (Factory-wired).
11. Connect MSG and SD terminals of the brake unit to a correct destination. Wrong connection results in the converter unit and
brake unit malfunction.
12. For connecting L
and L - terminals of TE2-1 of the converter unit to the terminal block, use the cable indicated in (3) (d) of
this section.
