Drive Set-up
Typically the system will contain an AC30P/AC30D regen drive providing 4-Q power supply, and one or more drives on the common DC bus.
ALL drives in the system MUST
have their internal EMC “Y” caps to earth disconnected.
A 4-Q regen drive is set into AFE control mode by setting the
Control Mode “Motor Type or AFE”
parameter to AFE as shown in picture below.
This setting must be accompanied by selection of an appropriate AFE macro from the default application:
If the
“Motor Type or AFE” and “Selected Application” do not match, it would not be possible to operate the drive correctly.Both these settings are
necessary for proper configuration of the drive to work as an active front end.
When drive is in AFE mode, its current rating is limited to 85% of the equivalent set up current rating when in one of the motor modes.
The standard set of AFE parameters required to finalise the drive AFE configuration are located within Setup/Regen Control menu. Based on the
“AFE Current Control” bit, AFE would operate in voltage control mode (left), or current control mode (right):
