executed and the Amp Enable output will be opened on QUAD and STEP axes.
C.5 Pressure/Force Parameters
C.5.1 Configuration Word (Pressure)
Default: 0x0000
Six bits of this 16-bit word control the configuration of the module. Bit 0 is the LSB; bit 15 is the
MSB.

Bits 12 - 14 - Analog Input Type bits
These bits are used to select the type of analog input being used. Use the following table to
select the appropriate input range:
Bit
14
Bit
13
Bit
12
Analog Input Type
0 0 0 Voltage: 0V to +10V
0 0 1 Voltage: -10V to +10V
0 1 0 Voltage: 0V to +5V
0 1 1 Voltage: -5V to +5V
1 0 0 Current: 4mA to 20mA
For a description of the corresponding transducer count ranges, refer to the Counts topic.
Bit 6 - Reverse Drive Mode bit
When this bit is set, the polarity of the axis’s output voltage is reversed. Notice that this only
affects the analog axis’s output. Therefore, for auxiliary pressure or force axis only Open Loop
commands are affected by this mode, and position/pressure control is not (recall that
position/pressure control uses the drive output of the position axis). However, for pressure-only
and force-only control axes, this will reverse the drive output when in Open Loop or pressure
control.
This bit is only useful when you are connected to two drives which do not have differential or
isolated inputs, and you need one to extend with positive drive and the other to extend with
negative drive. (If the drives have differential or isolated inputs, you can just reverse the
connections to the drive that must extend with negative drive.) When this bit is set, transducer
counts will DECREASE with positive drive.
Warning: This bit must be set properly when the Set Parameters command is issued.
Bit 5 - Absolute Mode bit
