Interfaces
4.5 Onboard drive interface (C230-2, C240)
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)
Analog voltage signal in the ±10 V range for the output of a speed setpoint.
• Reference potential (REFPOT)
Reference potential (analog ground) for the setpoint signal, connected internally to logic
ground.
• Controller enable (CTREN)
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.
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.
