System general description
Installation and start-up
6.
7.
The Camozzi DRCS drive has been developed to optimise the performance of Camozzi Stepper motors.
By using the micro-stepping technology (resolution up to 1/16 of step) it is possible to obtain a near-perfect sinusoidal
current, thus significantly reducing the natural resonance of the motor.
Many different control methods are available:
• Digital control: the availability of 7 inputs allows the realisation of a command table of 128 lines and for each command
line it is possible to set the position, the speed, the acceleration and deceleration. Each command can be either absolute
or relative.
• Frequency control: it is possible to configure the drive frequency control using commands Step and Direction.
The step rate defines the speed and the number of steps defines the position.
• CANopen control (only for models DRCS-XXX-X-C-X-X): it is possible to control the DRCS drive via CANopen (profile
standards CiA301 and CiA402)
The DRCS drive can be configured via USB or wirelessly using the Bluetooth protocol (only for models DRCS-XXX-X-X-X-B).
The DRCS drive is configurable through Camozzi’s software QSet (for more details on using this configurator and its
features, refer to the specific manual).
• During unpacking, take great care not to damage the product.
• Check if there are any faults from transportation or storage of the product.
• Separate all packaging material to allow for the recovery or disposal in accordance with current regulations in the country of use.
• Before using the component, ensure that the stated specifications and performance features correspond to what is required.
• During installation, ensure that suitable surge protection devices are used.
• During installation, verify that no hazards due to mechanical movements are introduced.
• Install the component in an area where the set-up and maintenance operations are easily performed without creating a
hazard for the operator.
• Isolate any unused connection wires with suitable safety caps or covers.
• The components must be fixed properly, where possible, using appropriate fasteners and ensuring that the fixture remains
effective even when the actuator operates at a high frequency or in the presence of strong vibrations.
• In the event of strong vibrations, provide suitable devices or systems that can dampen the effect these vibrations have
on the drive.
• Provide for the installation of dehumidifiers in order to prevent moisture or condensation in the internal components.
• If the device is used to operate an actuator of which any accidental movement can create a hazard, provide suitable
locking devices on the mobile section of the actuator.
• Ensure that the connectors are connected and secured properly.
• The device can be fastened on a DIN rail with the appropriate accessory, PCF-E520, mounted on the rear of the body.
• The component can be fixed directly to a support using the 8 holes (2 of which have an M6 thread) present on the both
sides of the body.

7.1 DRCS Power Supply
When choosing the power supply, adhere to all regulatory and safety requirements of the DRCS drive, presented in this
manual.
It is important to choose the correct voltage and current.
It is important to use power supplies equipped with “soft start” to avoid inrush currents that could damage the DRCS drive.
• Voltage
The supply voltage must be regulated and stabilised so as to avoid losses in speed and torque.
For Stepper motors, the voltage is directly proportional to motor speed.
• Current
The required current should be the sum of the two phase currents, but the DRCS drive controls the current with frequency
modulation, so it requires less current. In particular, the current required when operating at 24V will be double than that
required when operating at 48V.
In order to size the power supply correctly, we recommend using a power supply with double the expected current
capacity and analyse the operation at full load with a current probe. This will indicate the maximum current rating
required for successful operation.
• The information that follows shows the pinouts and details of the various connector ports located on the front of the
DRCS module:
Inside the DRCS drive, there is a non-resettable fuse that protects the logic circuit. If a replaceable fuse is necessary,
connect a 3A fast-blow fuse externally, in-line with the power cable. The logic power is applied to the LOGIC 24V
connector; use copper wires with an AWG22 cross section.
Warning: reversing the positive and negative poles can damage the DRCS drive.
Inside the DRCS drive, there is a non-resettable fuse that protects the logic circuit. If a replaceable fuse is necessary, connect
an 8A ultra fast (FF) blow fuse externally, in-line with the power cable.
The motor power is applied to the POWER 48V connector; use copper wires with an AWG18 cross section.
Warning: reversing the positive and negative poles can damage the DRCS drive.
7.2 DRCS Encoder
A differential connection for the encoder powered with +5V is available and a single-ended connection connects the signals
A+, B+ and Z+ to the +5V. The following picture shows the internal connection on DRCS drive.

It is possible to connect two proximity switches, one for Homing functionality and another for various functions:
1. Extra stroke sensor
2. Stop movement command (use it for stop the movement before to reach the target position)
Is possible to use both NPN and PNP proximity switches.
Stepper motors can have 4- or 8- wire configurations; the following pictures show these configurations and the connections
for the most common types of Stepper motors. The motor must be connected to the MOTOR connector:
4-wire motor:
8-wire motor:
As shown in the following picture, the 8-wire motors permit two different connection schemes: series or parallel.
In the series connection scheme, the high-speed torque is lower, but the losses and operating temperature are also reduced.
With this scheme, it is recommended to decrease the phase current by at least 30%.
In the parallel connection scheme, the torque and speed of the motor follow the torque-speed characteristic curve.

The DRCS drive allows for the connection of a DC electromechanical brake; the control current must exceed 0.6A.
The brake is controlled automatically by synchronising with the enable signal:
- If the enable signal (ENB) is enabled, the brake is open (brake powered)
- If the enable signal (ENB) is disabled, the brake is closed (brake not powered)
7.8 Inputs
- Proximity (PIN 2): an extra stroke/stop input that, if set, causes the motor to stop using the ramp deceleration setted by
the actual movement.
- Homing input (PIN 3): defines the zero position; the method used to conduct the Homing procedure is configurable with
Camozzi’s QSet software (for more details on using the configurator, specifically this feature, refer to the manual).
In order to activate the Homing procedure, it is necessary to follow these steps:
- Deactivate all inputs, from IN0 to IN7
- Activate the Enable input
- Activate the Strobe input: the procedure starts with the rising edge.
Digital Inputs IN0-IN6
The digital inputs’ common pin (EXCOM) can be connected to either the negative or positive pole of the power supply.
Every program line set in QSet (for more details on using the configurator, specifically this feature, refer to the manual)
corresponds to the binary combination of digital inputs as shown on the following page:

The maximum number of selectable individual lines is 127 (Line 0 is reserved for Homing.
It is possible to connect either PNP or NPN devices to the inputs.
If the PNP type is desired, connect the EXCOM signal (pin 14 on I/O connector) to the negative pole of the power supply
(GND); otherwise, if NPN type is desired, connect EXCOM (pin 14 on I/O connector) to the positive pole of the power
supply (+24V).
The following picture show examples of each type of connection:
IN7 and IN6
Via the QSet software is possible to set some external Jog commands to the driver; by using IN7 and IN6 inputs
(respectively pin 6 and pin 7 on IO connector) is possible to command with pulse. Using IN7 and IN6 inputs as Jog
command, the number of row in the table showed above will be reduced from 127 rows to 63 command rows.
7.9 Outputs
The DRCS drive provides 5 open collector outputs (NPN type) with a common pin (GND_O) when is necessary to connect
this pin to the negative poles of the power supply and a differential output. The maximum current for Alarm and Busy
output is 50ma with maximum voltage 80 V DC, for the others outputs the limits are 150mA and 300V.
If the load is inductive (eg. a relay), it is necessary to connect a flyback diode.
If the load is an input module (eg. a PLC), connect a reverse-polarity protection device, if not already provided by the input
module.
If the load could require a current greater than the maximum, connect a resistor in order to limit the current.
When an output is activated, its level is low, for exempla the Alarm output level is high without error, but the level became
low when an error is present: in this way is easy to identify an error on cabling or a cable break.

on using the configurator, specifically this feature, refer to the manual) as either PNP or NPN type, as shown below.
7.10 Steps to realise a movement
• In QSet, configure one or more command lines and load them to the DRCS drive using the “PC to Drive” command.
Example: position 100 mm, velocity 500 mm/s, acceleration and deceleration 100 mm/s2 entered into row 1:
- Enable the DRCS drive by setting the Enable input (ENB).
- Deactivate all digital inputs (from IN0 to IN6) and verify, by observing the Ready output (RDY), that the DRCS drive is
ready. If yes, generate a pulse (minimum width of 2ms) on the Strobe input (STB); the Homing procedure then starts and
the Busy output (BSY) becomes active until the motion has ended.
- When the Homing procedure ends (refer to the Homing OK output (HOK), change the IN0 state to 1 and hold the inputs
IN1 ÷ IN6 at 0.
- Verify the Ready output (RDY) value and, if the DRCS drive is ready, generate a pulse (minimum width of 2ms) on the
strobe input (STB).
- When the movement starts, the In Position output (POS) is deactivated and the Busy output (BSY) is activated until the
motion ends.
- When the motion ends, the In Position output (POS) becomes active, the Busy output (BSY) is deactivated.
• The user must adopt the necessary measures to prevent damage to the system caused by voltage spikes on the power lines
as a result of power outages of high-energy equipment.
• The DRCS board does have protection against reverse polarity of the power supply voltage.
• To improve noise immunity and prevent damage, it is recommended to connect the device to the system ground using any
of the holes in the aluminium body, and attaching the conductor to the metal plate.
• Only for models DRCS-XXX-X-C-X-X, it is possible to set the node address, its baud rate (up to 1 M/s) and enable the
CANopen communication mode (disabled by default) via the QSet configuration software (for more details on using the
configurator, specifically this feature, refer to the manual).
If the DRCS drive is the last node of the CANopen segment, it is necessary to use the termination resistor for the bus: the
order code EC-060623 is for a DRCS drive that has this resistor installed, which can be mounted on one of the two
CANopen connectors.
• To configure the DRCS drive, download the QSet software setup file from http://www.camozzi.com and proceed with
installation following the on-screen instructions. For more details, please refer to the QSet manual.
The connection to the DRCS drive is standard Micro USB (available as an accessory: G11W-G12W-2); communication
is only possible if the USB driver is correctly installed on PC.
The USB driver is installed automatically during the QSet installation.
7.11 PC requirements
• On start-up of the QSet software, the system verifies communication between the DRCS drive and the PC where the
configuration software is installed. In the event of communication failure, an error message is displayed.
