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.
