Introduction Due to its construction, the rotational speed of a 3-phase AC motor is directly dependent on the frequency of the voltage and the number of poles. In case of a 3PH 50Hz voltage and a 2-pole motor, the nominal speed would be 50 rps * 60 = 3000 rpm. In case of BLDC motors (brushless dc), the speed is directly dependent on the voltage applied. 3-phase AC motors provide numerous benefits in industry, such as brushless operation, freedom from wear and tear, favorable capacity/weight ratio, high-speed capability, and much more. These motors can be used many different application...

Start/Stop Interface for periodical tests or remote control Operating panel is detachable and can be used as remote control together with an extension cable Designed for roughest use in industrial environment The housing of SSE is realized without ventilations slots and an outside mounted heatsink. preventing by this the intrusion of dirt and chips of tooling. Very compact case style makes easy cabinet mounting possible Several case options for cabinet mounting (SSE) , 19" rack style and desktop, or special designs on request User friendly Screw-plug connector system for power-, spindle-...

S Operation of Asynchronous AC und BLDC Motors S The high frequency converter SFU-0303 makes possible output frequencies 3.3 kHz / 200.000 Upm with 2pole AC-Motors and with BLDC-Motors up to 100.000rpm S High output power ( 3,6kV @ 230V / 2kVA @ 115V ) in compact style S The core of SFU-0303 is a Digital Signal Processor (DSP) which produces all output signals and collects all input signals S All parameters like current, voltage and frequency are collected in real time and are regulated by the implemented vector control depending on the load condition. S High precision sinusoidal output...

Operating conditions 5 - 40°C / rel. Humidity of air max. 85% A The operation of a spindle with a wrong characteristic may harm the spindle severely! Please ensure to have the proper characteristic selected always!

Safety- Precautions and Warnings This device produces dangerous electrical voltages and is used for the operation of fast spinning tools. Because of their high rotational speed, it may be dangerous in case of improper handling. For this reason, only professionally trained and qualified personnel should be allowed to work with and setup this device! Before the first commissioning can be carried out, it should be ensured that the spindle and the tool are fixed properly, to eliminate all dangers because of uncontrolled movement of the spindle. Safety regulations being valid for the country...

Connections, Interfaces and Pinouts For embedding into PLC and controls the SFU0303 has several input and outputs. They are realized as pluggable screw terminals and are located at the front or rear panel (depending on case option). All contacts are separated galvanically from high voltage carrying circuits. Operational parameters and outputs: The SFU-0303 captures all current important operational parameters and operating data. Up to 6 digital outputs can be used for signaling and up to 2 analogue values can be output to the analogue outputs (0-10V) . Remote Control and Outputs: 6 digital...

The Default-settings of the functions for the outputs can be set up freely with the help of the PC-Software SFU-Terminal. An exception is the signal "Power Stage Pulse Lock", which is linked fix with Relay 6. According to the switch state it will be output 0V / GND or +24V via 10kQ referring to GND (X2.9) (-> 8.2 / 8.7) +24V: Output Power Stage released 0V: Output Power Stage locked. S Relay Output: 1) default = "not energized" corresponds to "not active" o inactive condition at opener (NC contact) -> Contact closed o inactive condition at closer (NO contact) -> Contact opened...

The Default-settings of the functions for the inputs can be set up freely with the help of the PC-Software SFU-Terminal. The inputs of the encoder and the PTC are fixed wired. ✓ The spindle interface is separated with optocouplers from all other signals. It can be used for an automatic spindle detection, if activated. The logic levels are low-active by default: ✓ "HI" > PIN connected with Spindle-GND, "LO"- > PIN unwired In the menu "Digital Inputs" this can be changed. ✓ GND signal X4 is electrically isolated from GND X2 ✓ The input "PTC" is provided for detection of excess temperature of...
