1-12 General Information
MN1269
Optional Adjustments
Each servo control contains six jumper settings and a personality module that can be
used to custom tailor the module to the application (for location see Figure 1-4).
Underlined positions indicate the factory default settings.
P1
Right position (pins 1 and 2) when normally opened switches are used.
Left position (pins 2 and 3) when normally closed switches are used.
P2
Right position when using a differential input.
Left position for single ended input.
P3
Right position for reading actual current (+ or –) on the DCS current monitor.
Left position for the absolute value. (always positive)
P4
Right position for EC (Excess Current) latch function
Left position for current foldback mode, where current is limited to a lower fixed
level.
(See Appendix B)
P5
A factory installed resistor (P5) which is on–board the personality module. This
is to ensure that the servo control will not function without the personality mod-
ule in the socket.
P6
Left position for velocity mode operation.
Right position for current mode and for use in positioning applications with
Personality Module
The personality module has 3 after factory adjustable settings (for location, see Figure
1-4). With the appropriate 1 % resistor soldered into the socket, peak current, RMS
current, and the foldback level can be adjusted. Motor compensation values are also on
this module, allowing custom compensation on specialty motors. These components are
already appropriate for Baldor DC servomotors. For a description of the current settings,
see Appendix B.)
Set Up Testpoints
Six testpoints have been added to help with set up and the replacement of a card. Once
a card is set up, the potentiometer’s resistance can be measured and recorded for future
reference. Other cards can be preset to these values minimizing the need to set up each
card on the particular piece of equipment.

“A” Pot Wiper Resistance
TP3
“S” Pot Wiper Resistance

Reset Button
A momentary push button (SW1) is mounted on the top of the servo control card next to
the adjustment potentiometers (for location, see Figure 1-4). This allows you to restart
(reset) a control that has shut down.
