1. Introduction Due to its construction, the rotational speed of a 3‐phase Asynchronous‐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 Synchronous‐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, ...

Operating panel is detachable and can be used as remote control together with an extension cable. Cloning capability of the whole project setup with the help of the Operating Panel Designed for roughest use in industrial environment Specific construction of the SSE‐housing realized without ventilations slots and an outside mounted heatsink prevents intrusion of dirt and chips of tooling into the control unit. Very compact case style makes easy cabinet mounting possible ...

High operational safety: All operating conditions like acceleration, operation with nominal rotational speed, deceleration is monitored and critical conditions are intercepted.

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. ...

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: ...

S Analogue input range: 0.10V S The +24V at Pin 10 can be used as auxiliary voltage supply for Start / Stop signal with the help of a relay or for an electronic spindle interface.

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 10kΩ referring to GND (X2.9) (‐> 8.2 / 8.7) +24V: Output Power Stage released 0V: Output Power Stage locked. ...

2) With SFU-Terminal the "active" function of the relays can be changed to "not energized " also. By this an inversion is achieved, with the restriction that this is applied to the inverter during operation at POWER-ON, only, because it is just realized by software. At POWER-OFF, the relay contacts have the default setting as in 1 ) S The digital outputs (Relay1...5) are galvanically separated (500VIsolation).

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 temperature sensor input is provided to detect overtemperature on the spindle. With linear temperature sensors (KTY, PT1000), the switching thresholds for the error messages ...

View at screw terminals at version SSE: The device has no internal fusing. It has to be fused externally Please ensure, that PE protective earth is connected at the mains side. The device must not be operated without properly connected PE! A Please ensure, that PE protective earth is connected at the spindle side as well as at the converter side. A Control wires. Mains cables and spindle cables should be installed separately. For wiring, the use of shielded cables is recommended.
