Note
Please refer to the online help for more information about parameterizing and
using the measuring sockets.
Properties
S Concurrent injection to several drives possible.
S The following parameterizable signal shapes can be set:
– Square-wave
– Staircase
– Triangular
– PRBS (pseudo random binary signal, white noise)
– Sinusoidal
S An offset is possible for each signal. The ramp-up to the offset is
parameterizable. Signal generation begins after the ramp-up to the offset.
S Restriction of the output signal to the minimum and maximum value settable.
S Operating modes of the ramp-function generator for servo and vector
– Connector output
S Operating modes of the ramp-function generator (servo only)
– Current setpoint downstream of filter (current setpoint filter)
– Disturbing torque (downstream of current setpoint filter)
– Speed setpoint downstream of filter (speed setpoint filter)
– Current setpoint upstream of filter (current setpoint filter)
– Speed setpoint upstream of filter (speed setpoint filter)
