The circuit board communicates directly with PC elements for rapid positioning in which the
pulse generator is used for feedback of actual values. A processor is provided on the circuit
board for the fast calculation in the inner loop of the positioning system. The positioning board
has a flexible design and is intended to perform several functions, together with different PC
elements:
• POS-A(0) Length measurement
• POS-A(1) Positioning with analog output signal
• POS-O(0) Positioning with digital output signal for three speeds
• POS-O(1) Positioning with digital output signal which can be pulsed
• POS-L Length measurement with digital output signal with coincidence.
The following functions and properties are available:
– Position measurement via an incremental pulse transmitter and a direction
discriminator and a hardware counter which updates a software counter at regular
intervals.
– Three pulse inputs adapted for the ABB pulse generator QGFA 110: A channel,
B channel and STROBE. Maximum frequency 80 kHz.
– Analog output for speed reference, 11 bits + sign. 0 to ±10 V or 0 to ±20 mA.
– Position control ON-OFF with fast, medium-speed or slow retardation to the interval
“correct position.” Position control ON-OFF with pulsed control. At low speed, the
output signal is not constant but is pulsed forward to the “correct position” with pulse
lengths varying with the deviation from the “correct position.”
– Functions on the board are supervised by means of self-testing. Faults are indicated
by the illumination of LEDs on the board.
For a detailed explanation of the positioning system, see the manual3RVLWLRQLQJ6\VWHP.

These functions are used for different applications in the industry, such as position
measurement, flow measurement, speed measurement, synchronization of machine movements,
and so on. The pulse-counting function requires special hardware.
• The cycle time for the reading-in program is determined individually with the parameters
in a DB element. After the reading-in, the values are converted to process-related units and
checked against limits. The limits which are exceeded are stored in the data base.
• The pulse-counting/frequency measurement function requires hardware module
DSDP 150. This circuit board is used for both pulse counting and frequency measurement
and has inputs which can be connected to pulse generators with a frequency of up to
10 kHz.
• DSDP 170 is a circuit board which is primarily intended for positioning/length and
speed/frequency measuring. Maximum pulse frequency is 2.5 MHz.
• DP820 is a module which is primarily intended for positioning/length and speed/frequency
measuring. Maximum pulse frequency is 1.5 MHz.
