5. Click Update RMC.
6. The Update Module Configuration dialog box will be displayed to indicate the progress. If the
RMC could not be reset automatically, you may be prompted to reset the RMC manually.
7. In the RMC Configuration dialog box, click Close.
Each channel-assignment option button gives the assignment of both channels. Some options
assign the channel to a joint purpose, as in the case of differential force, some assign the
channels to different purposes, and some assign the channels to the same purpose. Following
are descriptions for each individual channel assignment:
• Position Control
This mode uses a single analog channel and an analog drive output. Standard closed-loop
position control may be performed on this axis.
• Position Reference
This mode uses a single analog channel. This channel does not have an output and therefore
cannot be used as in closed-loop control, but instead may provide a reference for another
controlling axis. A common use for this type of axis is to serve as the master to another axis from
a signal generated from a PLC or joystick.
• Velocity Control
This mode uses a single analog channel and an analog drive output. The input channel value is
assumed to indicate velocity, as given by a device such as a tachometer or velocity-control
joystick. The drive output will work in conjunction with the input channel to control the speed of
the axis.
• Velocity Reference
This mode uses a single analog channel. The input channel value is assumed to indicate velocity,
as given by a device such as a tachometer or velocity-control joystick. This channel does not
have an output and therefore cannot be used as in closed-loop control, but instead may provide a
reference for another controlling axis. A common use for this type of axis is to serve as the
master to another axis from a speed signal generated from a PLC or velocity-control joystick.
• Pressure Control
This mode uses a single analog channel and an analog drive output. The input channel is
connected to a pressure transducer, the drive output is connected to the pressure-controlling
valve or motor, and they work together to hold a pressure or ramp the pressure in closed-loop
control.
• Pressure Reference
This mode uses a single analog channel. The input channel is connected to a pressure
transducer, but because it has no drive output, it cannot close the loop. Therefore, this input can
only be used as a reference for another pressure control input. That is, a pressure control
input/output pair can use a pressure reference input as its target pressure.
• Auxiliary Pressure
This mode uses a single analog channel. This mode acts the same as Pressure Control mode
described above, except that there is no drive output, so another axis’ drive output must be used.
The most common reason for doing so is to have a system with a position-to-pressure transition.
In this case, a position control axis is assigned to the auxiliary pressure channel. The position
transducer is connected to the position control axis’ input, the pressure transducer is connected
to the pressure channel, and each of the position and pressure inputs use the drive output when it
is in control.
