4.10.2 Automatic mode
If the safety facilities have been installed completely, the motor drive will usually
work in this automatic mode. The user can only use all motor drive functions in
automatic mode. Total safety of the gate is guaranteed here by the activated
safety facilities.
Opening or closing the gate can be initiated in automatic mode by means of the
backplane and (see chapter 5.8):
•
two command keys OPEN, CLOSE (work as dead man’s keys while
learning the limits)
•
one impulse input with toggle function OPEN, STOP, CLOSE, STOP
•
3x3 impulse inputs for OPEN, STOP and CLOSE commands
•
1 impulse input with PART OPEN function
Every movement command causes the full action that has been selected to be
performed (open gate, close gate etc.). Every action is stopped immediately by a
stop command or a signal from the safety facilities.
Activating the safety edge causes the gate to immediately move in the opposite
direction. If a photocell is interrupted while the gate is closing, this will cause the
gate to be opened as far as the point where the closing movement started (OPEN
or PARTLY OPEN).
A movement command for the opposite direction will gradually decelerate the gate
and then cause it to move in opposite direction.
Automatic mode if the gate has not been installed fully yet:
If the gate has not been fully installed yet, or if motor drive programming
has not been completed yet, the motor drive will work in a special safety
mode (e.g.: the end positions of the gate have not been defined yet). The gate
will then only run at dead man's mode speed. Only after the OPEN and CLOSED
end positions have been set and after a measuring run at dead man's mode speed
has been performed, will the system switch over to the automatic mode speed
(depending on the type, HMD230/HGD230/IGD230), this will be 0.25 m/s or 0.5
m/s). If the power supply to the drive has been interrupted, the gate will also only
run at dead man's mode speed until the first time when an end position has been
reached.
