The actual values (encoder values) of the drives are transferred from the IM 174 to the motion control vai PROFIBUS DP. The position controller of the control unit calculates the speed setpoint. This value is transferred to the IM 174 via PROFIBUS DP and then output to the drives.
The IM 174 PROFIBUS module permits the connection of up to 4 drives to motion controls via the isochronous PROFIBUS DP. Both electrical and hydraulic drives or stepper drives with analog setpoint interface or pulse-direction interface can be connected. The IM 174 is a PROFIBUS DP slave for operation on the isochronous PROFIBUS DP.
