Remarks:
−
It is possible to adjust speed of the micro annular gear pump with the
potentiometer without the need to connect the serial interface.
−
With the analog nominal value input (connection clamps »AnIN« and »GND«)
it is possible to adjust speed of the pump with a standard signal 0-10°V. For
this purpose it is necessary to plug the jumper on the S-ND control unit from
the »AnalogPoti« to the »AnalogExtern«. The serial interface does not need to
be connected.
−
In case of an overcurrent error the green status LED on the S-ND control unit
turns red
−
The standard programs memorized in the motor control unit may be started
with the tumbler switch S1. Basic sample programs are shown in the
chapter 7. For more advanced programs please refer to the user manual for
Motion Controller MCDC3006.
Startup of the pump with the S-ND control units with network mode (NET1
Command)
All standard units are delivered with node number 0. In order to prepare the units
for network operation, they must first be individually connected to the PC and set
to the desired node address using the FAULHABER Motion Manager.
A serial network can be constructed using the so-called daisy-chain technique, in
which the transmit cable of the Master (PC, PLC) is connected to the receive cable
of the first node, from where it is looped through to the receive cable of the
second node, and so on. The same procedure is followed with the receive cable
of the Master, which is looped through to all transmit cables of the drive node.
The current generation of Motion Controllers do not require a multiplexer board
for serial network operation. The multiplex mode is activated with a command
NET1.
