The measurement mode must be used each time the moving part has to pass outside module control (moving part moved by hand or controlled by an exterior device). In this mode the module remains passive, but continues to update the position (%IDr.m.c.0) and current speed (%IDr.m.c.2) information bits.
Selection of Measurement Mode
Measurement mode is selected by assigning the value of 0 to the MOD_SEL (%QWr.m.c.0) word.
The module also selects measurement mode while the PLC is in STOP mode. By default, it is selected following channel configuration.
Execution of Commands in Measurement Mode
OFF mode is not associated with any movement commands.
Movement of the moving part is not monitored and software fault checks are inhibited (except soft stop checks). The position loop is inoperative.
The variable speed controller enable relay is unlocked whatever the status of the ENABLE (%Qr.m.c.9) bit.
