Drive data and system data

• Identical electronics and software for the 48XX/49XX series

• Digital speed feedback by resolver or incremental encoder

• Torque control with speed control of the drives for winding technology

• Angular regulation for drift-free positioning

• Coupling of the master frequency as setpoint distribution or setpoint cascade for

- angular synchronization

- speed synchronization

- synchronization with speed difference

• Increased maximum armature voltage to 1.15 UN due to possible switching from 4-quadrant to 2-quadrant operation for 49XX

• Speed ​​accuracy greater than 0.5‰ for 100% alternating loads, with resolver or incremental encoder feedback

• Speed ​​adjustment range 1:1000 for constant load with resolver feedback or incremental encoder

• Current setting range 1:300 thanks to interrupted current adaptation and bridge modulation

• Limitation of the armature current according to the speed

• Maximum armature current programmable from 1.125 to 1.8 times the nominal current of the device (depending on the size)

• Switchable process controller for dancer control or traction control, for example

• Integration of excitation current regulation, resulting in a wider speed adjustment range

• Possibility of saving 4 sets of customer-specific parameters (switchable by digital input terminal for example)

Ordered

• ONLINE programming (engine running) of adjustment parameters

• Programming and diagnosis using

- a keyboard and a 2-line LCD display with text display in German, English and French

- serial interface and personal computer

- fieldbus module (optional): PROFIBUS, InterBus

• Uncoded fault messages

Speed ​​Loopbacks

• Resolver loopback with encoder simulation for additional systems

(synchronization, position control etc.)

• Incremental encoder feedback

• Speed ​​regulation by DC tacho

• Armature voltage regulation

Starters

• Digital inputs

- 8 galvanically isolated inputs (24 V power supply), including 5 programmable inputs

- 1 RS485 or RS232 serial interface (1200 ... 9600 baud)

• Analog inputs

- 4 programmable inputs (13 bit resolution)

for main setpoint, additional setpoint, torque limitation and others

Exits

• Digital outputs

- 8 galvanically isolated outputs (24 V power supply), including 5 programmable outputs

- 7 additional free outputs, assessable via LECOM interface

- 1 relay output (50 V; 0.5 A), programmable

• Analog outputs

- 2 reference voltages (10 V, 7 mA)

- 1 image output, programmed Ireal

- 2 image outputs, programmable (choice of 37 different signals with 11-bit resolution)

- 1 frequency output, programmable

Monitoring functions

• Functions for monitoring drive components and system components

• Speed ​​controller protection (I t function)

• Motor overload protection (I2 t function)

• Network frequency and voltage monitoring

• Automatic synchronization for network frequencies of 50 to 60 Hz

• Operating safety ensured with clockwise and anti-clockwise rotating field supply

• Actual value feedback monitoring

• Possible display of controller blocking sources via codes

• Several possibilities for announcing a fault (TRIP fault, message or warning)

• Cooling air monitoring for 4X08 to 4X13

• Monitoring of semiconductor fuses for 4X11 and 4X13
