Product description
The AdControl serves as an interface modification between a DriveControl 200/ DriveControl 300 and a RollerDrive
EC310. If the RollerDrive EC300 of a conveyor is replaced with a RollerDrive EC310, but the DriveControl 200/300
is to remain, the AdControl ensures that the signals (speed and direction of rotation) of a DriveControl 200/300
are converted in such a way that a RollerDrive EC310 can be connected that behaves in exactly the same way as a
RollerDrive EC300. The AdControl can also be used if the RollerDrive EC300 has been actuated without DriveControl.
Functions
Regenerative breaking
When the RollerDrive motor brakes, it acts as a generator and feeds energy back into the power supply. The
AdControl has a built in brake chopper (load resistor) to limit the DC voltage on the connection to a stable level.
Diagnostics
LEDs indicate the operating condition of the AdControl and the RollerDrive as well as the operating voltage (see
„Meaning of the LED”, page 20). An error signal can also be output.
Speed conversion
Because the RollerDrive EC310 has other gear phases just like the RollerDrive EC300, the RollerDrive EC310
would rotate at a different speed when actuated in the same way. The AdControl converts the speed signal of the
DriveControl 200/300 in such a way that the RollerDrive EC310 rotates at the same speed as a previously used
RollerDrive EC300.
Energy feedback
When the speed of a rotating RollerDrive is abruptly reduced (e. g. by removing or reducing the start signal at the
DriveControl), the RollerDrive continues to rotate briefly (depending on the weight of the conveyed goods being
stopped) and thus functions as a generator. The voltage generated in this way increases the supply voltage of the
RollerDrive. This increased voltage is partly fed to the DC supply (to max. 30 V) and partly converted to heat via a
brake chopper resistance on the DriveControl. The regenerated power is then available for other consumers. The
more precisely 24 V are complied to in the voltage supply the greater the voltage range in which the DC network can
be fed back to.
