PCP VOLUMETRIC PUMP DRIVE
1 INTRODUCTION
1.1 The manual
The user manual is the document that accompanies the pump from the moment of its construction and for the entire period of
use, it is therefore an integral part of the pump. The manual must be read before undertaking any operation involving the pump.
The manual must be readily available to personnel assigned to use and maintenance of the pump. The user and the person
responsible for use are required to know the contents of this manual. Reproduction of any part of this manual, in any form,
without the express written permission of DAV Tech is prohibited. The texts and illustrations contained in the manual are not
intended to be binding, DAV tech reserves the right, at any time and without notice, to make any changes to improve the product
or for constructive or commercial needs.
1.2 Warranty
The warranty is valid for a period of 12 months starting from the commissioning date and in any case not later than 15
months from the delivery date. Interventions carried out during the warranty period do not in any way extend the warranty
period. The seller is not liable for defects due to the normal wear of parts which, by their nature, are subject to wear.
1.3 Goods receipt
Upon receipt of the goods, check that:
• The packaging is intact.
• The exact correspondence of the ordered material.
The original drive configuration must definitely not be changed.
2 TECHNICAL DESCRIPTION
2.1 Operation
The controller was created to manage the movement of a PCP pump with DC motor with feedback from an encoder.
The DMD1204PN controller has Profinet IO and Modbus TCP / IP connectivity via ethernet, this allows the drive to be controlled
by most PLCs.
The device internally manages a “ Modbus Server” in addition to the IO Device, it must therefore be interrogated by another
Client device to read and write data.
The configuration of the Profinet interface can be managed directly from the development PLC tool used, as the functions for
assigning the device name and ip address are standard and are already managed directly by the drive.
The parameterization and the programming of the drive is simple and fast thanks to DC Control, the Tool supplied with an
advanced graphic interface for Windows able to communicate with the drive both with USB and with Ethernet.
The drive already contains a software that manages the PCP pump in all its aspects, enabling, dispensing, suck-back function,
possible outlet valve etc., this program can be parameterized with the variables exchanged with the PLC via Profinet or Modbus
TCP / IP.

Operating instructions
4.4 Power supply
The drive power supply will be 24VDC as it is also the rated voltage of the motor.
The drive has 2 separate power supplies, one for the logic and one for the power, this is to make
it possible to cut the power of the pump from a safety circuit, even if the pump is not considered
dangerous as it has no moving part on the outside. The maximum absorption for a PCP pump is
about 2.5 A while the drive logic is about 200-300mA.
It is advisable to use cables with a minimum section of 1 mm² for connections with a length of less
than 20 m and at least 2.5 mm2 in the case of connections with a longer length (maximum length
allowed = 20 m).
Use 4- core twisted pair and shielded cables.
4.5 Ground connections
It is preferable to use a ground bar that acts as a collector especially if there are several drives
connected.
It is important to connect to ground:
• the gnd of the power supply
• the drive housing
• the expected connection provided on the power terminal board
• the power cable screen (connected via the terminal of the power terminal board)
• the encoder cable screen.
4.6 Power connector

• bring power to the drive
• connection of the motor power supply

4.7 Control connector
Instead, the control connector provides:
• to supply power to the IO side of the drive
• connection of the encoder signals
• connection of the digital inputs and outputs
• connection of the analog input
To reduce EMI disturbances, it is required to install a ferrite filter at a maximum distance of 150 mm
from the drive on the motor cable.
The filter is composed of low-grade ferrite which has high radio frequency losses; in this way the
filter works as a high impedance at those frequencies.
Recommended ferrites:

Code 1463444 74271132

Length 39,4 mm 40,5 mm
25 MHz impedance 144 Ω 141 Ω
100 MHz impedance 240 Ω 241 Ω

Operating instructions
The digital outputs are protected against overloads (Max 500mA) and short-circuits; in case of
overload the output will switch off until the anomaly is removed.
If inductive loads, such as relays, solenoid valves, etc. have to be driven, connect a flyback diode in
parallel to the load.

PCP VOLUMETRIC PUMP DRIVE
The drive has been designed to perform all the dispensing functions necessary for a PCP pump,
these functions can all be parameterized via Modbus TCP IP, without this communication it will be
possible to use the drive with only one static data set.
By using the inputs or variables via Modbus it is possible to activate the following functions in the
drive:
Enable (Power Enable)
With input 1 it is possible to couple the pump motor, if the power supply is missing or the pump is
physically disconnected, the drive will give the power timeout alarm.
5.3 Drive logic
Using SSP 1 and SSP 2 input, it is possible to control the electronic disconnector integrated into
the drive with both 24 V signals and to supply the power stage of the drive.
5.1 Electronic power disconnector
The drive prepares a connection for the differential encoder signals, it is therefore possible to
connect the encoder line driver directly to the drive. It is possible to power the encoder directly
with 5V present on terminal board M2.
5.2 Encoder signals
Jog Dispensing
With input 2 it is possible to activate the pump to dose at constant speed, by turning off the
command the pump will stop immediately.
Predetermined dispensing
With input 8 it is possible to activate the dispensing of a set quantity, the input must be kept
active until the end of dispensing, the “End of dispensing” signal will then be activated when the
command is switched off.
Alarms reset
The designated input is input 9.
Suck back
The drive automatically performs the suck back (inversion of the rotation); whenever the controlled
pump stops, the direction of rotation is reversed with programmable speed and quantity.
INPUT PIN Description
IN 1 12 Enable
IN 2 27 Jog dispensing
IN 8 9 Predetermined dispensing
IN 9 10 Reset

Operating instructions
There are also 4 outputs that define the drive’s status:
Alarm
When 1 or more hardware alarms are active in the drive
Ready
When there are no alarms and the motor is in torque (enable active)
End of dispensing
Signal that activates at the end of a predetermined dispensing
Dispensing in progress
Signal that allows you to connect for example a solenoid at the output of the pump (with a
programmable delay)
The drive in the upper part has 2 ethernet ports which are related to a single network interface.
It is possible to insert one or more drives into the PLC network configuration using the supplied
GSDML file. The real time data exchange must be configured in the Drive using the “PROFIdrive
AEC Telegram 500 “ (programmable delay).
This telegram sets up the exchange of 10 INT32 variables for the inputs and 10 INT32 variables for
the outputs (40 + 40 Byte).
