Technical description 8100_A
The process control sequence determines the main set-value and the Ti time of the
corresponding ramp function generator in a sequence and time which can be
programmed. The process control comprises a maximum of eight steps. Each step
can be assigned the following parameters (see 7.6.20):
- one frequency set-value (using C211)
- one pair of acceleration and deceleration times (using C212)
- the duration (using C213)
-the following step (using C214)
If the process control is activated, each step which has been reached is displayed
under C160. Each step can also be output as a signal via one of the freely
programmable digital output terminals using C117.
The process control is interrupted and reset on step 1 by one of the following
actions:
-controller inhibit
- quick stop
- trip fault indication
After having cancelled the interruption, the controller starts with step 1, unless the
process control is inhibited first. Over- or undervoltage indications do not influence
the process contro!.
Functions, which may influence the main reference, such as
-invert set-value
- ramp function generator input
= zero
- ramp function generator stop
- DC injection braking
are available during the process contro!. For example, the time of the momentary
step continues while the DC brake is activated. During the process control, set-value
(C049) is set to zero. The deceleration time set under C221 remains active.
7.3.5 ENABLEJOG SET-VALUEC045
Terminal control:
According to the assignment of the JOG set-values to the digital input terminals, the
JOG enable results from the binary coding of the input terminals (see 7.6.6).
This function can be assigned to a maximum of four digital inputs. Therefore, 1, 3, 7
or 15 binary coded JOG-set-values are possible when assigned.
