R/L1
Main circuit power supply input
To connect a commercial
power supply.
S/L2
T/L3
U/T1
Drive output To connect a motor.V/T2
W/T3
B1
Braking resistor connection -
To connect a braking resistor
or braking resistor unit.
B2
+2
• DC power supply input
(+1 and -)
• DC reactor connection
(+1 and +2)
-
To connect peripheral
devices, for example:
• DC power input
• Braking Unit
• DC Link Choke
Note:
Remove the jumper
between terminals +1
and +2 to connect a DC
link choke.
+1
DC power supply input (+1
and -)
• DC power supply input (+1 and -)
• Braking unit connection (+3 and -)
-
+3 -
• 200 V: D class grounding (ground to 100 Ω or less)
• 400 V: C class grounding (ground to 10 Ω or less)
To ground the drive.
Note:
Use terminals - and B1 to connect a CDBR-type control unit to drive models 2004 to 2138 and 4002 to 4168 that have built-in braking
transistors.
