+CICO: INPUT CONTACTOR
This option makes it possible for you to connect or disconnect the drive from mains. To do it,
use a control switch on the control compartment door, or connect an external switch to
terminals –XD0. To connect the external switch, refer to the electrical drawings.
The option includes the fuse switch (+CIFD) for safety reasons.
When your product is MR10 with minimum 416 A, the option includes additional cabinet
sections.
The wiring of the option can be seen in chapter 5.1.1 Main circuit diagrams of the cabinet.
The requirements: +CAPU Auxiliary AC supply terminals or +CAPT Auxiliary voltage
transformer
+DBIN: BRAKE CHOPPER
The power unit has a dynamic brake chopper. The external brake resistor is connected
directly to the brake resistor terminals of the power unit, see chapter 5.4.1 Installing the
cables. The brake resistor is not included in the option.
+POCM: COMMON MODE FILTER
The option includes an output filter that decreases the common mode voltage. The filter is
connected between the motor cable terminals of the power unit and the motor cable
terminals of the drive. The filter does not have an effect on the connection of the external
motor cables.
The wiring of the option can be seen in chapter 5.1.1 Main circuit diagrams of the cabinet.
+PODU: DU/DT FILTER
The option includes an output filter that increases the rise time of the voltage pulse, and thus
decreases the voltage stress on the motor winding insulation.
The filter is connected between the motor cable terminals of the power unit and the motor
cable terminals of the drive. The filter does not have an effect on the connection of the
external motor cables. With this option, the maximum length of motor cables is 150 m. If the
cables are longer than 150 m, use a sine filter option.
The wiring of the option can be seen in chapter 5.1.1 Main circuit diagrams of the cabinet.
The requirements: Not +COSI Sine filter.
+COSI: SINE FILTER
The option includes an output filter that removes the switching frequency. The output filter
leaves only the output frequency and thus eliminates all voltage stress on the motor. The
filter is connected after the motor cable terminals of the AC drive. The filter is located in an
additional cabinet section. The option is necessary if the motor requires filtering, and if
longer than 150 meter cables are used. The option can also be used with shorter cables if
necessary. If you use long cables, we recommend you to use the common mode filter option
(+POCM) also.
