Commands for specifying setpoints
NOTE
The commands described here for specifying setpoints are not used for standard applications.
9.4.1 Inching
See also Section 8, function diagram Sheet G129
The INCHING function can be preset via the binectors selected with indices .01 to .08 of parameter
P435 or via bits 8 and 9 of control word 1.
When the control word option is used, the following operating modes are possible (see also function
diagram, Sheet G180):
P648 = 9: The control bits in control word 1 are input bit-serially. The binectors selected in P668 and
P669 determine bits 8 and 9 of control word 1 and thus the input of the INCH command.
P648
≠
9: The connector selected via P648 is used as control word 1.
Bits 8 and 9 of this control the INCHING input.
The “inching” function can only be executed when “Shutdown” ("0" signal on terminal 37) and “enable
operation” ("1" signal on terminal 38) are applied.
The "Inch" command is input when one or several of the named sources (binectors, bits in control
word) change to the log. "1" state. In this case, a setpoint selected in parameter P436 is assigned to
each source.
An inching setpoint of 0 is applied if the inch command is input by two or more sources simultaneously.
Parameter P437 can be set to define for each possible inch command source (binector, bit in control
word - logic operation, see block diagram in Section 8) whether or not the ramp-function generator
must be bypassed. When the ramp generator is bypassed, it operates with ramp-up/down times of 0.
Sequence of operations for entering Inching command:
If “Inch” is specified, any “line contactor” which may be used is switched on (if controlled using B0124)
and the inching setpoint is applied (procedure as for “Switch on / Shutdown”).
Sequence of operations for cancellation of Inching:
After the "Inch" command has been cancelled, the sequence of operations commences in the same
way as for "Shutdown". After n < n
min
has been reached, the controllers are disabled and the line
contactor opened after a parameterizable delay (P085) of between 0 and 60 sec. if controlled via
B0124 (operating state 07.0 or higher). The drive remains in operating state 01.3 while the
parameterizable delay period (max. 60.0 s) runs down.
