Siemens SIMOTION C Operating Instructions Manual page 47

Signal type
O - signal output
VO - voltage output
K - switching contact
Drives with analog interface
Signals:
One voltage signal and one enable signal are provided per axis.
● Setpoint (SETP)
● Reference potential (REFPOT)
● Controller enable (CTREN)
Note: When used as a digital output, the contact must be supplied with voltage.
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 correctly and
that the necessary safety regulations are met.
SIMOTION C
Operating Instructions, 02/2012
Analog voltage signal in the ±10 V range for the output of a speed setpoint.
Reference potential (analog ground) for the setpoint signal, connected internally to logic
ground.
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 signaled by the user program.
WARNING
3.5 Onboard drive interface (C230-2, C240)
