extension interfaces of the handle to the normally-open contacts of Switch K1 (self-recovery), and
set the IO number to 12 in the “switch to suspension mode” menu. Connect the 10
th
pin and the 6
th
pin on the extension interfaces of the handle to the normally-open contacts of Switch K2
(self-recovery), and set the IO number to 13 in the “switch to suspension unloading mode” menu.
Connect the 11
th
pin and the 6
th
pin on the extension interfaces of the handle to the normally-open
contacts of Switch K3 (self-recovery), and set the IO number to 15 in the “switch to unloading
mode” menu. When the contacts of the inching switch K1 is connected in a “locking mode”, the
equipment switches from the “locking mode” to the “suspension mode”. When the contacts of the
inching switch K2 is connected in a “locking mode”, the equipment switches from the “locking
mode” to the “suspension unloading mode”. When the contacts of the inching switch K3 is
connected in a “locking mode”, the equipment switches from the “locking mode” to the
“unloading mode”.
5.3 Double limit function
The equipment only uses the setting parameters in the soft limit 1 by default. By configuring
the IO signal of the extended port, the system can use the setting parameters in the soft limit 1 or
soft limit 2. By controlling the input of the extended port IO signal, the user can easily implement
the switching between the soft limit 1 or 2 of the lifting equipment, which is suitable for the user’s
changing requirements for soft limit in the application.
5.3.1
Usage Method
The switching double limit signal can be input by the host extension, handle extension, or
expansion board input port. Set the corresponding IO number in “Extended Function Settings” →
“Extended Port Settings” → “Switch Double Limits”.
For example:
Take the 11
th
pin of the handle extension interface as the double limit signal
input. Connect the 11
th
and 6
th
pins of the handle extension interface to the normally open contacts
of the (self-recovery) switch, and then set the IO number to 14 in “Switching Double Limits”.
When the switch contact is turned on, the soft limit used by the system is switched from soft limit
1 to soft limit 2. When the button is triggered again, the soft limit used by the system is switched
from soft limit 2 to soft limit 1. With the trigger of the button, the limit used by the system is
cyclically switched between soft limit 1 and soft limit.
Note:
The function and parameter setting method of soft limit 2 is the same as soft limit 1.
When double limits are used, the soft limit mode switch must be selected as the signal
switch!
