Speed feedback systems
( Resolver feedback with encoder emulation for superimposed systems
(synchronizing systems, positioning controls, etc.)
( Incremental encoder feedback
( DC tacho feedback
( Armature voltage feedback
Inputs
( Digital
- 8 isolated inputs (24 V level), 5 of them freely assignable
- 1 serial interface RS 485 or RS 232 (1200 ... 9600 baud)
( Analog
- 4 freely assignable inputs (13 bit resolution)
e.g. for main setpoint, additional setpoint, torque limitation, etc.
Outputs
( Digital
- 8 isolated outputs (24 V level), 5 of them freely assignable
- Another 7 free outputs can be evaluated via the LECOM interface
- 1 relay output (50V; 0,5A), freely assignable
( Analog
- 2 reference voltages ( –10V, 7mA)
- 1 monitor output, with I
- 2 monitor outputs, freely assignable (37 different signals with 11 bit
resolution selectable)
- 1 frequency output, freely assignable
Monitoring
( Monitoring functions of the system and controller components
( Controller protection (Iôt function)
( Motor overload protection (I
( Monitoring of frequency and mains voltage
( Self-synchronisation for mains frequencies from 50 to 60Hz
( Safe operation with CW or CCW direction of rotating field input
( Monitoring of the act.-value encoder feedback
( Display of the sources of controller inhibit via a code
( Classifiable monitoring (TRIP, message or warning)
( Monitoring of the cooling air stream with 4X08 to 4X13
( Monitoring of the semiconductor fuses with 4X11 to 4X13
act
ôt function)
