2.12 Notes on commissioning linear motors
Temperature evaluation unit with safe electrical separation
Terminal Module 120 is a temperature evaluation unit with DRIVE-CLiQ interface for
installation in a control cabinet. The TM120 has 4 measuring channels with safe electrical
separation to connect KTY or PTC temperature sensors. A TM120 can also be used with
Sensor Modules for encoder evaluation (SMCxx, SMIxx and SMExx) if safe electrical
separation of the temperature sensors is necessary.
Evaluating the temperature sensors
For additional information, refer to the Configuration Manual of the 1FN1, 1FN3 or 1FN6
linear motors.
2.12.5

Measuring system

Determining the control sense
The control sense of an axis is correct if the positive direction of the drive (= clockwise
rotating field U, V, W) coincides with the positive counting direction of the measuring system.
Note
The data to determine the drive direction is only valid for Siemens motors (1FNx motors).
If the positive direction of the drive and positive counting direction of the measuring system
do not match, the actual speed value (P0410.0) must be inverted in the "Encoder
configuration - details" screen form when the drive is being commissioned.
The control sense can also be checked by first parameterizing the drive, and then manually
moving it, with the enable signals inhibited (switched out).
If the axis is pushed in the positive direction, the actual speed value must also count in the
positive direction.
