Decimal places of the measured variable

Depending on the type of the selected touchprobe source, the measured variable is output with or without decimal places. The decimal places used are determined during runtime of the IEC program when activating the touchprobe function (set xActivate to TRUE).

The following table shows which decimal places are used:

Touchprobe source

Data source

Decimal places

Inverter

Actual position
in system units

Actual position
in user units

Decimal places of the encoder used for position control (is read from configuration data)

Actual position in user units – Modulo

Decimal places of the encoder used for position control (is read from configuration data)

Encoder 1 – Actual position in system units

Encoder 1 – Actual position in user units

Decimal places encoder 1 (is read from inverter)

Encoder 1 – Actual position in user units – modulo

Decimal places encoder 1 (is read from inverter)

Encoder 2 – Actual position in system units

Encoder 2 – Actual position in user units

Decimal places encoder 2 (is read from inverter)
NOTE: This data source is only permitted for single axes.

Encoder 2 – Actual position in user units – modulo

Decimal places encoder 2 (is read from inverter, data source only permitted for single axes!)
