Compact controller with a ColdFire CPU, with a base as big as a C5 envelope.
Description and equipment of our controller BES/S4 as pdf
Differences to the BES/C (not mentioned features as with BES/C, see info):
- The controller is limited to 4 stepping motor axes. (Four existing separate connectors with the signal outputs.)
No operation possible with usual servo motors, however it is possible to actuate motors with SERCOS III, so the possible number of axes increases to 8.
Stepping and servo axes are mixable in the case of an operation with SERCOS III. E.g. a machine with SERCOS servo motors may dispose of a tool changer with a stepping motor.
- No expansion capability of the existing outputs and inputs.
Apart from the essential ports for PC, keyboard, axes, reference switch, spindle and emergency stop, further available: 9 spared sensor inputs and 12 spared switch outputs (for tool changer, edge sensor etc.).
(In case of an operation of motors via SERCOS III additional sensor inputs are available, which are at the SERCOS power driver.)
- Maximum output frequency: 350 kHz (BES/C: 450 kHz).
Thereby e.g. speeds up to 10 m/min are reachable with micro stepping of 10.000 pulsings per motor rotation and a spindle with 5mm pitch.
The scale of the axes may differ here, too, divider head operation or rotary axis are possible.
(Up to 900 kHz output frequency are available on request.)
- Low wiring effort in the machine. E.g. direct connection of the reference switch to the controller (one plug terminal per switch) without a separate terminal strip.
The connectors to the PC and the keyboard are located at the front side. It is possible to mount the housing inside the machine in a way that the connectors are directly accessible from the outside.
(Connection to SERCOS drivers perhaps with a network cable.)
- Compact housing 220mm x 165mm x 51mm.
- Shared 24V-power adapter to power the controller and the machine components.
Included in the delivery: power adapter 24V, 2A for DIN rail assembling.
The controller including the keyboard M24 requires ca. 500mA. So 1.5A are still on hand for machine components. (The controller needs a higher supply current during the usage of other keyboards, a lower supply current without a keyboard.)
- As an option an operation without a machine keyboard M24/M25 is possible (cost saving)
Separate start- and stop-buttons are connectable to that end. But this leads to constricted operation options. The machine is then adapted via PC.
- Lower price.
- During the refitting/modernization of existing machines, advantages of the BES/S4 occur as opposed to other controllers.
- Cost-efficient but even so powerful.
- An easy connecting of the components (e.g. one plug terminal per limit switch). An easy connecting and trying during the refitting of deprecated milling controllers etc.).
- Flexible, multiple adjustment possibilities e.g. if different drive spindles are used in the axes (necessary e.g. during the refitting of Wissner machines).
- Because the BES/S4 is equipped with four axes, it is not just suited for simple machines, but also for machines
- which e.g. have a rotary axis,
- or machines with two Z-axes.
- It is even possible, that two Z-axes are used, that are making a depth detection separatly, and that enables in this way a double efficiency during the production by usage of an eletric depth detection.
