Chapter 6 Configure and Start the Kinetix 5700 Drive System
6. Click the AC Line category.
Source Power is the kVA rating of the transformer feeding the
regenerative power supply. The default Source Power setting is 10 times
the power rating of the regenerative power supply.
When the transformer rating is less than the regenerative power supply
rating, enter the kVA rating of the transformer.
The Source Power attribute applies detuning and current limiting only
when Source Power is set lower than the rating of the regenerative power
supply (1/10 of default).
7. Click the DC Bus category.
External bus capacitance is the sum of all drive and accessory module
capacitance.
8. Manually calculate the sum of the drive and accessory module
capacitance values and enter the External Bus Capacitance value.
See Calculate System and External-bus Capacitance
on page 376 to
calculate external bus capacitance.
IMPORTANT
An accurate bus capacitance value is required for proper
operation.
