Evaluating the Homing Points and Limit Switch
22
The following are the available
inputs and signals:
■
Analog Input
■
Fault Pin (programmed as
input)
■
Input No. 3
■
Zero Index of Hall Sensor
The inputs can be evaluated in
varying ways:
■
Direct programming with
HA, HL, HN commands
■
Programmable Homing
Sequence
■
Hard Blocking Function
■
Hall Index Sequence
The Arguement in the Limit
Switch Commands
The arguement portion of the
Limit Switch Commands
(HA,HL,HN,HP,HD and HB) is a
number which defines the
appropriate limit switch with
binary code.

A binary ‘1’ usually means an activation of that input.
A ‘0’ deactivates that input.
Example:
HA0 ... Deactivate Home Arming at all Limit Switches
HA1 ... Activate Home Arming at Analog Input, deactivate all
others
HA2 ... Activate Home Arming at the Fault Pin, deactivate all
others
HA3 ... Activate Home Arming at both the Fault Pin and the
Analog Input
HA4 ... Activate Home Arming at Input 3
HA5 ... Activate Home Arming at Input 3 and the Analog Input
HA6 ... Activate Home Arming at Input 3 and the Fault Pin
HA7 ... Activate Home Arming at all limit switches
The command table describes only what a “1” and a “0” mean at
the appropriate binary point.
Programming the Fault Pin as a Limit Switch
Command Function
Description
Example
REFIN *)
Reference
Sets the Fault Output to
REFIN
Input
function as a limit switch input.
ERROUT *)
Error Output
Switches to Fault Output
ERROUT
mode
Important:
The Fault Pin input function is only active if the REFIN
is activated. (Save setups with the EEPSAV command !)
