Activation of the programs and sequences (programs 1 - 15, sequences 1 - 3)
At activation from the terminal blocks the permitted programs, sequences (even more than one) can be activated from
digital or virtual inputs, at any point of time. The condition of their operation is that the frequency converter is in start
state.
At direct start, the activation effects also start at the same time, independently of the start switches.
At the end of the sequence, according to the menu items type and end, the program returns to the default setting, it
stops or repeats cyclic.
In case of selecting cycle, if the activation ceases, the equipment returns to the default setting or stops, according to the
settings. At repeated activation, the cyclic operation starts again!
The programs and sequences in case of activation (in order of their priorities) take over the operation from the default
setting. If a program or sequence gives over the control because its time elapsed, it can only be started again, if it will
be activated after an inactive state! (That is, the input is to be switched off and on!)
At activation in case of Start, the permitted program or sequence will be started by the start command. In this case, no
digital inputs are needed for running.
At the end of running, it returns to the default setting according to the menu item end, it stops, or repeats cyclic.
The commands stop, spin out and DC brake can stop the operation!
Example for activating from the terminal block
If for any parameter the value “N” is set, it means that in case of this parameter the program takes into consideration the
default setting!
If in Program 1 the setting is N, 32.0%, N, N, 5s, then at activating the actual digital input:
• in case of regulation the default setting prevails, because the regulation reference signal is not active,
• in case of control, the reference signal of the used control is 32.0%, independently of the value of the selected
reference signal source (potentiometer, terminal),
• rise and fall of the reference signal occurs according to the default setting,
• the time duration is limited to 5s.
Since the time duration is set to 5s, this state will exist for 5s after the beginning of the program run, and independently
of the level the drive reached, after 5s the reference signal of the originally selected reference signal source will prevail.
However, if also program 2 is activated, then after the elapse of time 1, the operation continues with the parameters set
in program 2.
Consequently, if e.g. a 4-steps program is to be performed, then activating inputs program 1 to program 4 have to be
joined up, and activated at the same time during start, when the programs are to be started.
(In lack of start, the run of the programs written on the activated inputs starts at the appearance of the start command.)
A simpler solution of the previous task is if the previous 4 programs will be designated as the programs to be performed
of a sequence, since in this case only the sequence needs to be activated with an input, and the programs will run in
the way described previously.
If during operation an input of higher priority activates again, then it will take back the operation from the one of lower
priority!
