Wiring Examples
This section provides wiring examples to connect a Braking Unit and other peripheral devices to the main
circuits, examples of wiring a transformer to Inverter I/O, and other aspects of Inverter wiring.
îš‹ Using a Braking Resistor Unit
This example shows wiring for a Braking Resistor Unit.
CIMR-G7A20P4 to -G7A2015 (200 V Class Inverters of 0.4 to 15 kW)
CIMR-G7A40P4 to -G7A4015 (400 V Class Inverters of 0.4 to 15 kW)
* 1. A transformer is not required for 200 V Class
* 2. Remove the short-circuit bar (normally connected) from 1 and 2 when connecting a DC Reactor (Optional).
* 3. Disable stall prevention during deceleration by setting L3-04 and using a Braking Resistor Unit. The motor may not stop within the decel-
eration time if this setting is not changed.
* 4. When connecting a separately-installed type Braking Unit (model CDBR) to Inverters with built-in braking transistor (200 V/400 V 15 kW
or less), connect the B1 terminal of the Inverter to the + terminal of the Braking Unit and connect the - terminal of the Inverter to the - ter-
minal of the Braking Unit. The B2 terminal is not used in this case.
