A-B 1747-L552/C CPU module

Controller Structure 

The velocity controller has been modified so that 

• the deep pass filter of the actual velocity value is dropped in parameter S-0-0392, Velocity feedback filter, 

• the variables (torque command) generated by the velocity controller can be filtered over a bandstop filter with programmable frequencies and bandwidth (Parameter P-0-0180, Rejection frequency velocity loop and P-0-0181, Rejection bandwidth velocity loop new) and

 • the deep pass can be set via P-0-0004, Velocity loop smoothing time constant to not effect the variables but rather the control deviations of the velocity controller.

Drive-Controlled Referencing 

The function Drive-controlled referencing has been expanded: 

• Encoder 1 (motor encoder) and 2 (optional encoder) can be referenced. 

• encoder with distance-coded reference marker is possible

 • via bit 7 in parameter S-0-0147, Referenzfahr-Parameter it can be selected whether the drive will go to the reference point or stands still after switching into the actual value coordinate system.

Analog Output 

The function Analog output was modified. It is now possible • to output some drive parameters with variable scaling via the digital/analog converter. (Parameter P-0-0426, Analog outputs, IDN list of assignable parameters, P-0-0420, Analog output 1 signal selection, P-0-0422, Analog output 1, scaling per 10V full scale, P0-0423, Analog output 2, signal selection and P-0-0425, Analog output 2, scaling per 10V full scale, new). • Any bits and bytes can be output via the expandes signal select. (Parameter P-0-0421, Analog output 1, expanded signal selection and P-0-0424, Analog output 2, expanded signal selection new). 

• Signals can be output via a list of permanently set signals.
