Output Sharing Chokes (for motoring drives only)

The following section covers the output sharing chokes which are currently available for Unidrive SP. These being used for the motoring drives in a
regen system only (between drive and motor).

OTL: Output sharing choke
Voltage rating
4: 380V to 480V
6: 500V to 690V
0: Single
1: Dual
Current rating step
NOTE
For the 200V SPMx modules used in parallel configurations and where output sharing chokes are required the 400V OTL output sharing chokes
should be used.
The following tables detail the output chokes required for the various configurations of paralleled SPMA and SPMD power modules.
When connecting either SPMA or SPMD drives in parallel
they must be de-rated by 5%
CAUTION
NOTE
In order to achieve the best possible current sharing between paralleled Unidrive SPM modules, sharing chokes must be fitted.

The OTLX1X centre tapped output sharing chokes can only
be used when two Unidrive SPM drives are paralleled
together. For all other combinations the OTLX0X output
sharing choke must be used.
