Example A
P10.9 = 1: Execute program cycle once.
table P10.10 = 0 (see table ): The fixed frequencies FF0 to FF7
(P10.1 - P10.8) are set in numerical order with the associated run
times (P10.10 - P10.18) and rotating direction (FWD) as setpoint.
The start command (RUN) for the sequence control is set via the
digital input (DI1 - DI6) defined at parameter P3.21. It has a higher
priority than other start commands. This also applies to the fixed
frequency setpoints of the sequence control compared to setpoint
sources.
If the start command (RUN) is switched off during the program
cycle, the drive stops according to the settings at P6.8. The
program sequence is then ended immediately. A renewed start
command begins once more with the first fixed frequency.
The operating states of the sequence control can be displayed via
the digital outputs RO1, RO2 and DO.
The following assignments are shown in example A:
• Relay RO1 (P5.1 = 16) signals the operation (RUN) of the
sequence control. It switches on with the start command and
then off after one completed program cycle (P10.9 = 1,
P10.9 = 3) at the end of the program cycle (P5.3 = 18).
• a With a continuous program sequence (P10.9 = 2,
P10.9 = 4) the start signal is switched off first (P3.21).
• Relay RO2 (P5.2 = 17) indicates the end of the individual run
times (P10.11 - P10.18).
• Transistor DO (P5.3 = 18) indicates the end of a program cycle.
i
Warning!
If a start command is present at a digital input (DI1 - DI6)
assigned at P3.21, the sequence control also starts
automatically (without switch edge) when the power
supply is switched on (e.g. after a power supply failure)!
h
A digital input (DI1 - DI6) can be assigned the “Pause
sequence control” function at parameter 3.22. The
program sequence is then stopped and can then be
resumed from this stopping point (fixed frequency).
h
Value 19 (e.g. P5.3 = 19) enables a pause command
(P3.22) of the sequencing control to be indicated via a
digital output.
