Product catalog summary

Overview: This document provides comprehensive technical specifications, operational guidelines, and connection instructions for Static Frequency Converter models SFU 0101, 0201, and 1901-1902. It includes installation, operation, and safety measures.

Technical Specifications:

Equipped with a microcontroller for supervision, control, and closed-loop control.
Mains voltage: 230 V AC, 50/60 Hz.
Output power: 250 W (400 W short-term).
Output voltage: 3 x 0 ... 36 V (0...60 V).
Frequency range: 83 ... 1,000 Hz, 5,000...60,000 rpm (max. 1333 Hz, 80,000 rpm).
Weight and dimensions vary by model.

Connection Details:

Control connectors with specific pin configurations for relay connections, rotational speed, and emergency shutdown interlock.
Spindle connections for 3-phase power and additional sensors.

Operating Instructions:

Power switch initiates an automatic check upon activation.
Spindle operation is controlled via "START" and "STOP" buttons, with adjustable rotational speed.
Digital displays provide real-time feedback on rotational speed, load, and operational status.
Overload and excess temperature protections are in place, with visual indicators for faults.

General Comments:

Ensure equipment is in perfect condition before use.
Follow health and safety regulations during installation and operation.
Only trained personnel should handle the equipment.

Spindle Operation and Control:

Includes handling excess temperature and remote control capabilities.
Key displays indicate system status, such as excess temperature and rotational speed.
The spindle cannot be reactivated until specific displays disappear after a power-up.

Remote Control:

The spindle can be controlled remotely via a 15-pole SUB-D-JACK.
Options include using a potential-free contact or direct voltage for control.
Supports RS 232 serial interface for additional control.

Rotational Speed and Standstill:

Displays indicate when the spindle reaches the preset rotational speed or is at a standstill.
Uses magnetoresistors for accurate speed evaluation.

Configuration Options:

Two configurations available: rotational speed output and active load output, both requiring a magnetoresistor.

Reversing Direction of Rotation:

Requires applying a direct voltage when the spindle is stationary.

Emergency Shutdown Interlock:

Can be programmed to prevent the converter from restarting after an emergency stop, requiring a specific voltage to reset.

Special Accessories:

Optional accessories include a parameter manager and converter control software for Windows.

Guarantee and Company Standards:

BMR offers a 12-month guarantee against defects, excluding improper operation.
The company adheres to high ecological and quality standards, holding a DIN ISO 9001 certification since 1998.

General Comments Our high frequency converters are high quality precision devices. Be sure to handle them with the required care so as to ensure that their high degree of accuracy, excellent performance and long life expectancy are retained. The converters do not leave our works until after having been subjected to an extensive „load test“. Before installing the equipment, carefully read the instructions supplied with it. Additionally, the following rules should be observed: • Before commissioning, see that the equipment is in perfect condition. If the converter has • • • • • • • been damaged...

Operating Instructions GENERAL This Static Frequency Converter includes a microcontroller, which controls, supervises and regulates all functions, such as analogue and digital interfaces, evaluations, data inputs, respectively effective transmission-parameters; which can also be changed by software. POWER SWITCH After the Power-button is switched "ON"; the Static Frequency Converter starts an automatically check for about 8 seconds. During this time all displays flashes a short time one after another. After this automatical check the converter is ready for operation. In case of defect the corresponding...

= converter is not ready for operation = load of converter or load of spindle higher than 100% = spindle is not ready for operation = rotational speed reaches „desired value“ or „actual value“, respectively LOAD DISPLAY The load display indicates the present load of spindle in %. "green area" "red area" = within the admissibility = overload If the spindle is not loaded and no defect exists, the loaddisplay indicates approx. „0%“. OVERLOAD DISPLAY The display (2.3) always flashes, if the spindle was overloaded or the interruption for overload responded.
