SIMOTION C230-2, 04.2003 Edition
Drives with analog interface
Signals:
One voltage and one enable signal are provided per axis.
S SETPOINT (SW)
Analog voltage signal in the "10 V range for the output of a speed setpoint.
S REFERENCE SIGNAL (BS)
Reference potential (analog ground) for the setpoint signal, connected internally
to logic ground.
S CONTROLLER ENABLE (RF)
Contact assembly mated set (NO contact), used for axis-specific enabling of
the drive, e.g. a SIMODRIVE drive unit. The RF signal to the drive is set as
soon as the controller enable is signalled by the user program.
!
Warning
Brief voltage peaks may occur at the analog outputs when the supply voltage is
switched on or off.
For this reason, it is important to make sure that the enable signals are wired cor-
rectly and that the necessary safety regulations are met.
