Product information

3.1

Product description

The DriveControl is a control system for conveyor systems that regulates the speed and rotational direction of anInterroll RollerDrive.
Control system

RollerDrive to be used

DriveControl 20 NPN

EC 310, EC 5000 AI 24 V DC (20 W and 35 W)

Energy recovery/overvoltage protection
If the RollerDrive is stopped or the speed is abruptly reduced, the kinetic energy of the conveyed material in the
RollerDrive is converted into electrical energy, akin to a generator. This energy is fed back into the system, where it
can be used by other RollerDrive units.
If more energy is fed back than can be used, the excess energy is converted into heat via a brake chopper in the
DriveControl. The brake chopper becomes active when the voltage increases to over 26.5 V. This prevents excessively
high voltages within the system.

Overload protection
The brake chopper resistance is monitored in terms of temperature. If the brake chopper resistance is frequently
activated due to certain application properties (e.g. high weight of material to be conveyed or high conveyor speed),the DriveControl will be switched off whenever it gets too hot (an internal temperature of approx. 90 °C). Whenever
the temperature protection is active, this will be indicated via the LEDs and a start signal will no longer be sent to theRollerDrive. Once the DriveControl has cooled down, the RollerDrive will automatically switch on again whenever a
start signal is issued.
The DriveControl will cool down faster if it is mounted on a level surface, ideally one made of metal.

NOTE
Irreparable damage to the DriveControl through overheating¾

Do not carry out a power reset while the overload protection is active, as this causes faults to reoccur.

Blocking time for signal changes
The following signals are protected by the firmware to guarantee their functionality in the event of bouncing andinstability. This means that once a signal has been changed, the next signal change will only be processed after 20 ms.
• DIP switch SPEED A, SPEED B, SPEED C, SPEED D, DIR, RAMP
• Inputs for RollerDrive ERROR, SPEED A, SPEED B, SPEED C, DIR

When the operating voltage is switched off, the ERROR output will switch to the "error" state. This guarantees acorrect error message even when the error signal has been linked from multiple DriveControl units and the operating
voltage of a DriveControl unit is switched off, or a cable error has occurred (detached contact, cable break).
When the operating voltage is switched on, the error signal is issued until the internal microcontroller has assumed
control. If no error is present, the error signal is terminated approx. 400 ms after the operating voltage has beenswitched on.

NOTE
Incorrect polarity will irreparably damage the DriveControl.
Ensure that the polarity of the supply voltage VEXT is correct.

Start-up and operation

6.1

Start-up

Check before the initial start-up¾

Ensure that the base plate of the DriveControl has been correctly attached to the profile and that all screws
have been properly tightened.

¾

Ensure that no additional hazards are formed through the interfaces to other components.

¾

Ensure that the wiring conforms to the specifications and legal provisions.

¾

Check all protective equipment.

¾

Ensure that no persons are in the hazardous areas by the conveyor system.

6.2

Configuration options

Setting the speed
The speed of the RollerDrive can be adjusted via the DriveControl in two ways:• Internally, via a DIP switch. This method is given priority and allows for finer increments.
• Externally, via three digital inputs in eight levels (speed changes are also possible during operation, whereby aquasi ramp function can be implemented via corresponding circuitry of a PLC).
This speed setting is converted into an analogue control voltage by the DriveControl, which is then interpreted by
the RollerDrive as a target value setting. This target value setting is independent of the RollerDrive gears and theirdiameters.
The acceleration and deceleration characteristics of the RollerDrive are determined by their own moment of inertia,
the gears used, the conveyor speed, the moment of inertia of the connected conveyor rollers, the selected operating
medium and the transported mass.
The varying rated speeds and gear stages of the RollerDrive units used will result in different speeds.
• RollerDrive EC310 = rated speed 6000 rpm• RollerDrive EC5000 AI = rated speed 6900 rpm

29 of 42Start-up and operation

Speed preselection via digital inputs
Requirement: All DIP switches must be set to OFF.
¾

Set the external inputs for SPEED A, B, C to a logic level of (H)igh or (L)ow in accordance with the table below,
in order to start the RollerDrive at the desired speed.

¾

To adjust the speed, change the signals on the inputs SPEED A, B, C accordingly.

¾

To stop the RollerDrive, switch all the inputs SPEED A, B, C to a logic level of (L)ow.
The internal speed setting is given priority. If one or more of the internal DIP switches SPEED A, B, C, D
are set to ON while the speed is specified externally, the RollerDrive will rotate at this internally set speed,
independent of the signals from the external inputs. If all internal DIP switches SPEED A, B, C, D are set toOFF, the RollerDrive will once again rotate at the speed that is set through the external inputs.
