Keypad Hardware Features
Dipswitches
A bank of four dipswitches on the back of the keypad provide a way to lock
operators out of various keypad access levels.See the chart below for switch
assignments.If access to a menu level is denied,pressing that key will have no
effect. For example,if 1 is on,and 2 is off, the operator will be able to stop motion,
and program execution,(by pressing the escape key) but will not be able to access
the RUN menus to select another program to run.This is a hardware inhibit,and is
independent of any software,or setup parameter in the Smart Drive. Power must
be cycled before keypad dipswitch changes take effect.
In addition,access to the jog menu can be enabled or disabled from software.
Switch 3 and 4 are reserved for future functionality.
Contrast
On the back of the keypad,there is a single,plastic, flat head screw driver
adjustable,potentiometer.This is used to adjust the contrast on the LCD display. If
the Smart Drive and keypad were purchased together, this adjustment has been
made by IDC.Some adjustment may still be needed to accommodate unusual
lighting or viewing angles.
Remote Mounting
The keypad can easily be remote mounted and sealed to NEMA 4 specifications by
using the included mounting gasket and 6 foot communication cable.The gasket
should be installed with its adhesive side to the enclosure.A pressure seal is formed
between the gasket and the keypad,while the adhesive maintains the seal between
the enclosure and the gasket.The keypad communicates with the Smart Drive via
RS-232 so this cable can be extended if needed.At longer distances,users may have
to provide a separate 5 VDC supply to power the keypad.Complete keypad
drawings and pinouts can be found in the
Har dware Reference
chapter.
