Drives with analog interface
SINUMERIK 801
Start-Up
Signals:
A voltage and an enable signal are output.
AO4 (SETPOINT)
Analog voltage signal in the range ± 10 V to output a speed setpoint
AGND4 (REFERENCE SIGNAL)
Reference potential (analog ground) for the setpoint signal, internally
connected to logic ground.
SE4 (SERVO ENABLE)
Relay contact pair controlling the enable of the power section.
Signal parameters
The setpoint is output as an analog differential signal.
