3.9 Braking Resistor Installation
SIEPYEUOQ2A01G AC Drive Q2A Technical Manual
103
Figure 3.52 Install a Braking Resistor Unit: LKEB-Type
To install a braking resistor unit, set
L8-01 = 0 [3%ERF DBR Protection = Disabled]
.
Models 2004 to 2138 and 4002 to 4168 have a built-in braking transistor.
To prevent overheating the braking resistor unit, set a sequence to de-energize the drive at the trip contacts of the
thermal overload relay.
◆
Install a Braking Unit Connection: CDBR-Type
To install a CDBR type braking unit, connect te3 on the drive to te on the braking unit. Then
connect terminal - on the drive to terminal - on the braking unit. Te2 on the drive is not necessary for
CDBR-type braking unit connections.
Figure 3.53 Install a Braking Unit: CDBR-Type/Braking Resistor Unit: LKEB-Type
Set
L8-55 = 0 [DB IGBT Protection = Disable]
.
Note:
To install a CDBR-type braking unit to the drive models 2004 to 2138 and 4002 to 4168 that have a built-in braking transistor, connect
drive terminal B1 to te on the braking unit.
◆
Connect Braking Units in Parallel
To connect two or more braking units in parallel, wire and select connections as shown.
