Basic motion control configuration

PLC
ACSM1
PROFIBUS DP
EnDat
Absolute encoder
The PLC controls the ACSM1 drive through a PROFIBUS DP bus using the
PROFIdrive positioning mode. The drive is position-controlled and uses an absolute
encoder (4096/EnDat) installed on the motor. The mechanical gear ratio (1:20) and
pitch (6 mm / 1 rev) of the lead screw are taken into the drive's position control loop.
Limit switches and a home switch are used to determine the initial position of the
machine.
The jog input (DI2) is used to move the load manually close to the machine. If the
STO circuit is opened, the drive is not able to move the load at all.
