Upgrading From ALEC Series C to Series D
The Mode switches in the Series D no longer control the encoder
power output voltage. The Encoder Output voltage is now controlled
by the position of DIP switch 1. (See the section on DIP switches in
the Setup chapter of this manual.)
AxisLink Address Rotary Switch
The AxisLink Address rotary switch has been changed from a 10
position switch to a 16 position switch. The additional settings are for
accommodating the increased addresses that become available when
you are in Extended node AxisLink. Earlier version of the ALEC did
not support the Extended Node AxisLink. The DIP switch 2
determines whether AxisLink is in Extended or Standard Node. When
in Standard Node only rotary addresses 0-7 are available for use.
When it is in Extended Node the settings 0-F are available for use.
DIP Switches
The ALEC series D has added a bank of DIP switches. These were not
available in the series C. They change the way in which you
configure the ALEC series D from the ALEC Series C. This is most
notable for configuring the encoder properties and AxisLink.
