Fig. 3−32 Stand−by operation with selection via digital frequency
Function
l Stand−by operation is only possible during program operation.
l PS mode (C1311): Select 30...34 (stand−by operation and signal source for abort).
l In PS, stand−by operation is executed instead of positioning. As long as stand−by operation is
active, "positioning or special function" in the PS is not completed. The following PS functions
are only processed when stand−by operation is terminated (see diagrams).
l After having started stand−by operation, the drive is accelerated or decelerated to the external
speed setpoint at POS−N−N due to positioning. The profile parameters of the PS apply.
When reaching the speed, the external setpoint inputs (POS−N−IN, POS−P−IN) are used. From
now on, the position setpoint (POS−SETPOS) equals the actual position value (POS−ACTPOS):
POS−STDBY−ACT = HIGH
