RPM PROGRAMMING/READOUT
As shipped from the factory, the DS9000 is set up to accept a selected speed as RPM, and to display
motor speed in tach mode as RPM when used with a 60 pulse/revolution pulse generator. In this case,
no adjustments or calibrations are necessary. If a pulse generator with a different PPR rate is to be
used, the DS9000 must be calibrated to accept its input. To do so, with the DS9000 powered up, but
in Stop mode, and with Security OFF, select adjustment parameter FEd0. Refer to Section 4.2 for
parameter information on FEd0, SCF0 and SCd0.
The parameters with a 0 on the end are for set point controllers and the parameters ending in 1 are
programmed only when used as a follower controller. Set FEd0 as shown in Section 4.2. Note that the
maximum value of pulses/revolution times motor RPM permitted is 25,000. Next, select adjustment
parameter SCF0. This parameters sets the readout scale factor. Enter the actual maximum RPM or
maximum engineering unit to be displayed at the maximum motor speed.
3.2
ENGINEERING UNITS –PROGRAMMING/READOUT
The DS9000 may be used to control and display speed in units other than RPM, provided that the
units are in direct proportion to RPM and within the numerical constraints of the DS9000. Examples
of this feature could include: Gallons/minute in a pumping system, feet/minute of a conveyor, or
output RPM of a gear reducer. To scale the units, first check parameter FEd0 for the correct value of
pulses/revolution of the pulse generator to be used. Next, select adjustment parameter SCF0. This
parameter should be set to the readout desired when the MOTOR is running at the maximum speed.
Minimum value is 100, and maximum is 9999. To add further flexibility, a decimal point may be
located in the display. To select the decimal point position, select parameter SCd0. By entering 0, 1, 2,
or 3, the decimal point will appear in positions: XXXX, XXX.X, XX.XX, or X.XXX, respectively
allowing engineering units of 0.100 to 9999.
3.3
STARTING AND STOPPING
The DS9000 may be wired into the start/stop circuit of the motor controller or use the internal
DS9000 +5VDC supply. To start the DS9000, a DC voltage of between 5 and 25 volts must be applied
to terminals TB1-1 and TB1-2. Generally this can be obtained from the DC drive's Start/Stop logic
power supply. For use with typical SECO drives, See Figures 2.2 and 2.9.
To start the DS9000 with the +5V DC supply available on TB1-10 of the DS9000, connect TB1-10 to
TB1-2, and TB1-12 to TB1-1. A dry contact can be placed in series with the connection between TB1-
10 to TB1-2 to allow start/stop control from a switch, relay, PLC or other type of interface contact
closure.
CAUTION
Do not connect the common connection onTB1-9 or TB1-12 to the common on TB3-2. If you connect
the Start/Stop of the DS9000 to the drive Start/Stop circuitry (as shown in Fig. 2.3 of the Q7000), You
can connect TB1-1 to either the drive common or the DS9000 common but not both simultaneously
without damage to the drive and DS9000.
To start the DS9000 from the Start/Stop on the drive (such as the BRONCO II, SE2000, Q7000, etc.),
connect TB1-1 to the drive common (TB2-9 on the BRONCO II 160 series, TB2-11 on the SE2000, or
TB1-2 on the Q7000 series). Now that common is connected, connect TB1-2 to the drive terminal
point that is at a DC voltage level (i.e. –24V DC for the BRONCO II 160) when the drive has been
started. This would be TB2-3 on the BRONCO II 160 series, TB2-1 on the SE2000 series or TB1-9 on
the Q7000 series. For these drives or others, refer to the wiring diagrams for the particular drive that
you are using in their specific installation and service manual.
