4 Hardware Migration
Positioning for stepper drives (FM353)
Table 4-19
Function in S7-300
Input DI for reference point
Function Speed axes
Positioning
Traversing programs
G code programming
BOOST: Controlling the motor
current
Output DQ for pulse and direction
Note
Use the technology objects that output the setpoint via the TM PTO4 for
controlling. The pulses output are used as position feedback.
Positioning for servo drives (FM354)
Table 4-20
Function in S7-300
Input Incremental 5V
Absolute SSI
Function Speed axes
Positioning
Traversing programs
G code programming
Output AQ for speed setpoint
Note The "PositioningAxis" technology object is suitable for positioning with servo
drives. If you connect the servo drive directly via PROFINET, you can save the
position acquisition via TM PosInput2 and also the setpoint output via an analog
output. Through the modularization it is also possible to connect a 24V
incremental encoder to a TM Count 2x24V and to read the position this way.
