RollerDrive EC310
Product information
Product Description
The RollerDrive EC310 is an electronically commutated drive roller. The motor
electronics, motors and gears are installed in the RollerDrive . It has nine gear
stages and can be operated at a constant conveying speed.
Overload protection device There are several overload protection systems.
• Stall timing device: If the RollerDrive is stalled while there is a run command,
the motor tries to restart ten times every three seconds for one second. If the
stall persists after these ten attempts, a failure signal is set and the
RollerDrive tries to restart with a 60:1 cycle (restart for one second every 60
seconds) until the stall is eliminated. The RollerDrive will not be damaged if
the system operates in a stall time device mode for a long period of time. If the
RollerDrive is running at the selected speed again or the run command is
withdrawn, the failure signal will be cancelled.
• Slow running: If there is a speed deviation of +/- 20% from the chosen value
for more than 10 seconds, the motor will be switched off and the failure signal
will be set. The RollerDrive will try to start again after 60 seconds. If the
RollerDrive is running at the selected speed again or the run command is
withdrawn, the failure signal will be cancelled.
• Temperature monitoring: The temperature of the motor and electronic
assemblies is monitored.
If used appropriately, the roller can be installed in the conveyor with the required
controls and then operated maintenance-free throughout the service life of the
product.
Holding brake
(Zero Motion Hold)
The RollerDrive EC310 is fitted with an electronic holding brake that allows it to
be used on conveyors on a gradient or incline. The motor's rotor is held in
position if no travel signal is pending. In the event of failure of the supply voltage,
the holding brake becomes ineffective as it is not a mechanical brake.
Energy feedback The RollerDrive EC310 feeds energy back when the goods being conveyed
brake. This results in the motor heating up less in operation and improves the
energy efficiency of the system. Interroll DriveControls are fitted with a switch
that prevents the voltage rising above 28 V in the supply voltage. When installing
the system, ensure that the power units are capable of feedback.
