1 CLD+Linear Power Stage
In this chapter you’ll find a brief description of the CLD+power stage, the extent of supply,
the operation modes and the schematic diagram.
1.1 Short Overview
Fig. 1:Operator’s control and dimensions (mm)
Ministep power stage for 2 phase stepper motors
The CLD+is a linear power stage for 2 phase stepper motors for extreme low-noise
applications. The source of current is constructed with power operational amplifiers which
deliver load independent output currents.
The CLD+is the preferred solution power stage for extreme applications (e. g. measuring
applications), in which sensitive measures could be impaired by noise voltages. Due to the
linear design, noise emissions are nearly negligible.
Phytron power stages with the addendum + are particularly service-friendly by the
ServiceBus which enables configurating, operating and monitoring the power stage via
PC. For easy use of all setting options, the free ServiceBus-Comm®for Windows®software
is included in delivery.
The step resolution is entered by menu or by ServiceBus: full step to 1/512 step.

1.3 Operating Modes
The CLD+can be used in 3 operating modes:
1.3.1 Operating Mode ‚Menu-Driven‘
All operation parameters are menu-driven with the input keys in the Setup menu. In the
process the function S-BUS=DISABLED is defined.
1.3.2 Operating Mode ‚ServiceBus‘
The S-BUS=ENABLED in the Setup menu activates the ServiceBus mode and all settings
are made by ServiceBus. The parameter values are shown in the CLD+display during the
operation. It is not possible to change parameters with the input keys, acknowledged by
!S-BUS ENABLED (see chap. 9).
1.3.3 Operating Mode ‚Bus Mode Exclusive‘
The ‚bus mode exclusive‘ ensures safe operation in ServiceBus mode. If the power stage
is set to ‚Bus mode exclusive’ in the ServiceBus mode by ServiceBus-Comm (instruction
code ‚PX’), all settings with the menu buttons are ignored.
Leaving the mode is only possible via ServiceBus by the ‚PX‘ instruction code.

3 To Consider Before Installation
Read this manual very carefully before installing and operating the CLD+.
Observe the safety instructions in the following chapter!
3.1 Qualified Personnel
Design, installation and operation of systems using the CLD+may only be
performed by qualified and trained personnel.
These persons should be able to recognize and handle risks emerging from
electrical, mechanical or electronical system parts.
WARNING !
By persons without the proper training and qualification damages to devices and
persons might result!
3.2 Safety Instructions
1. Please observe the earthing instructions chap. 6.3!
2. In case of supply voltages > 24 V:
The CLD must only be operated if CLD+housing and motor housing are
connected to protective earth.
3. The connectors SUPPLY and MOTOR should be locked with the fixing
screws.
4. Up to 3 minutes after turning off the supply voltage, dangerous voltages
may still exist within the device.
5. Be careful handling the connectors „Motor“ at the CLD+and any motor
cable coupling.
As long as the CLD+is connected to supply voltage, a hazardous voltage level
is present at motor connector and motor cable, even if the motor is not wired.
6. Up to 3 minutes after turning off the supply voltage, dangerous voltages
may still exist at the CLD+connectors.
13 MA 2112-A002 GB

Manual CLD+
7. Always switch off the supply voltage if you connect or disconnect any wires or
connectors at the CLD+.
Most important:
Do not unplug the motor connector while powered.
Danger of electric arcing.
8. Voltages connected to the signal inputs and outputs (X3, X4 connectors) should be safely separated from mains. The maximum voltage against
protective earth must not exceed 60 VDC.
9. Clearing the DEACTIVATION input or deselection with the DESELECT input
or RESET is no protective separation in the emergency case.
The voltage supply has to be interrupted for switching off the drive safely.
10.The surface of the CLD+may reach temperatures of more than 70 °C.
Danger of injury if touching the surface!
MA 2112-A002 GB 14

phytron
3.3 Protective Measure Options
The control unit must be operated by the protective measure PELV acc. to VDE 0100. The
internal intermediate circuit voltage is connected to the motor housing. The line filter
should not be bridged, therefore it isn`t allowed to ground the supplied voltage.
The housing of the CLD+must be grounded, the motor can be grounded (see Fig. 4).
Fig. 4:PELV with SELV-Supply
Protective measure PELV for application of the +UBshould not exceed 50 VDC at
dry environment (environmental conditions 3 acc. to IEC 61201).
The supply transformer must be constructed with reinforced or double
insulation between supply and secondary winding (acc. to EN 61558).
Only use motors which are checked acc. to EN 60034-1 (500 VAC).

4 Mounting
In this chapter you will find all information about mounting the CLD+inside a switching
cabinet, cooling and supply of the fan.
4.1 Mounting Instructions
•The CLD+has been designed to be mounted inside a switching cabinet.
Depending on operating voltage and applicable standards, other
environments can also be permissible.
•The CLD+should be vertically mounted.
•Mount the CLD+device at a plane surface with appropriate load capacity
(device weight is about 1.1 kg).
Use the mounting kit delivered with the device for rail mounting or wall
mounting.
You may also use the mounting threads in the device’s back plate for
individual mounting solutions.
•The mounting screws used must
intrude not more than 3 mm into
the device inner parts!
< 3 mm
•Recommended free space below and above the device: 100 mm
Keep the air slots free to allow a convective air exchange!
•Recommended free space to other devices besides the CLD+: 30 mm.
•Recommended free space for cables and connectors before the front plate
of the device: 30 mm.
•The device has to be mounted and operated at a place free of shocks and
vibrations.

4.2 Temperature and Cooling Air Flow
If mounting several CLD+devices one upon another be sure that the requirements for
cooling air are met also at the topmost air inlet:
•The heat production in the CLD+devices proportionally depends on the motor current
used. It can be maximum 85 W at a rated voltage of 24 V.
•The maximum permissible ambient temperature depends on the phase current and
cooling air flow follows from the de-rating diagram (see below).
•The CLD+can be operated without an external fan with motor currents up to about
0.4 Amps, even at an ambient temperature of 40 °C.
•Using an external fan (Papst type 614 operated at 24 VDC) the CLD+can be operated
with 1.4 Amps phase current at a rated voltage of 24 V and an ambient temperature up
to 50 °C.
