Purpose
•
Implementation of a “Flying saw”, with additional function block interconnection (on request).
•
Enables the changeover between positioning and another setpoint source, e.g. master
frequency of a main drive.

Fig. 7-38 Stand-by operation with selection through master frequency
Function
•
Stand-by operation is only possible in manual operation.
•
PS mode (C1311): Select 30...34 (stand-by operation and signal source for abort).
•
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 the stand-by operation is terminated (see diagrams).
•
After having started the 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
