The commands are entered in the field »Enter command:«. The button »Send«
will send the command to the drive for execution (see figure 35). The commands
may be given alternatively in capital or lowercase letters. Excess space characters
will be ignored by the drive.

Command Description
SOR0
V1000
V0
V6000
SOR1
Set the nominal speed via the RS-232 interface
Operate the pump at 1000 rpm
(for the mzr-2521 with a displacement volume of 1.5 µl a flow
rate of 1.5 ml/min is obtained; for the mzr-2921 a flow rate of
3 ml/min)
Pump at rest (speed 0 rpm)
Operate the pump at 6000 rpm
(Flow rate: mzr-2521 = 9 ml/min; mzr-2921 = 18 ml/min)
Analog input operating mode: Set the nominal speed with
potentiometer or by connecting a voltage signal to the analog
input

M
SOR1
Set the nominal speed via the RS-232 interface
Load a relative position of 320 to the control unit
320 = 5 rotation cycles, displaced volume mzr-2521
≈
7.5 µl;
mzr-2921
≈
15 µl)
(
Remark
: 64 steps = 1 rotation)
Execute the task / start positioning
Load a relative position of 640 to the control unit
(640 = 10 rotation cycles, displaced volume mzr-2521
≈
15 µl;
mzr-2921
≈
30 µl)
Execute the task / start positioning
Analog input operating mode: Set the nominal speed with
potentiometer or by connecting a voltage signal to the analog
input
Because of the 4-edge evaluation of the encoder signal by the control unit S-ND a
quadruple number of counts per turn must always be given. In case gear box
module is used, the respective gear reduction must be taken into consideration.
