2. Mechanical Installation
Installation Requirements
Environment
ViX drives operate in a temperature range of 0°to 40°C with natural convection, or 50°C
Max with forced-air cooling (see Hardware Reference), at normal levels of humidity (5-95%
non-condensing). The drives can tolerate atmospheric pollution degree 2, which means only
dry, non-conductive pollution is acceptable.
Drive Cooling
Cooling of all drive types is by natural convection up to 40°C. To assist cooling, drives
should be installed vertically in an area where there is at least a 50mm (minimum) air gap
above and below the package and a 10mm (minimum) gap either side. Avoid mounting
heat-producing equipment directly below a drive.
Installers must ensure that the air temperature entering the drive or rising up to the drive is
within the ambient temperature restrictions. Under normal use the air temperature leaving
the drive and heatsink may be 25°C above ambient.
In the final installation, check that the ambient temperature specification of 40°C Max
(without forced air cooling) is not exceeded directly below the top-most drives and that any
circulating air flow is not being blocked from reaching the drives. For cabinet cooling
calculations, allow 20W per drive.

Drive Mounting Options
If you require a DIN-Rail mounting ViX drive use the DIN-Rail clip adapter bracket shown in
Figure 2-2.

Figure 2-2. DIN-Rail Adapter Bracket
Remove the panel mounting plate from the back of the drive and attach the bracket to the
back of the drive using the screws provided. The drive and bracket can now be fixed to a
DIN rail by hooking the top of the bracket over the top of the DIN rail and gently pushing the
drive forward to engage the lower section of the bracket. Remove the bracket by inserting a
flat bladed screwdriver into the release slot to pull down the bottom of the bracket, releasing
it from the DIN rail.
Thermal Limitations
If you are using DIN rail mounting with natural convection airflow cooling and the drive is
working under continuous load, the maximum continuous output torque should be de-rated
by 10%. For example, using the drive for reel tensioning rather than point-to-point
applications may require torque de-rating when using DIN rail mounting.

8VIX AH SERVO DRIVE USER GUIDE
Motor Mounting Mechanical Considerations
Keep motors securely fixed in position at all times. Do not test a motor/drive combination
without first securing the motor –see the Safety Warning at the front of this user guide.
CAUTION – risk of equipment damage
Do not back drive the motor, that is use the motor in an application that causes
mechanical rotation of the motor shaft in a manner uncontrolled by the drive.
Back driving the motor at high speed may damage the drive.

Installation Safety Requirements
ViX drives meet the requirements of both the European LVD & EMC directives when
installed according to the instructions given within this section. It is recommended the drive
be installed in an enclosure to protect it from atmospheric contaminants and to prevent
operator access while it has power applied. Metal equipment cabinets are ideally suited for
housing the equipment since they can provide operator protection, EMC screening, and can
be fitted with interlocks arranged to remove all hazardous motor and drive power when the
cabinet door is opened. Do not arrange interlocks to open circuit the motor phase
connections while the system is still powered, as this could cause damage to the drive.
Precautions
During installation, take the normal precautions against damage caused by electrostatic
discharges. Wear earth wrist straps. A switch or circuit breaker must be included in the
installation, which must be clearly marked as the disconnecting device and should be within
easy reach of the machine operator.
Cabinet Installation
To produce an EMC and LVD compliant installation we recommend that drives are mounted
within a steel equipment cabinet. This form of enclosure is not essential to achieving EMC
compliance, but does offer the benefits of operator protection and reduces the contamination
of the equipment from industrial processes.
A steel equipment cabinet will screen radiated emissions provided all panels are bonded to a
central earth point. Separate earth circuits are commonly used within equipment cabinets to
minimise the interaction between independent circuits. A circuit switching large currents and
sharing a common earth return with another low level signal circuit could conduct electrical
noise into the low level circuit, thereby possibly interfering with its operation. For this reason
so called ‘dirty earth’and ‘clean earth’circuits may be formed within the same cabinet, but all
such circuits will eventually need to be returned to the cabinet’s main star earth point.
Mount the individual drives and EMC filter on a metal earth plane. The earth plane will have
its own individual star point earth which should be hard wired (using an insulated copper
conductor) back to the cabinet’s ‘clean earth’connection point.

WARNING – Possible drive damage
If you use Parker XL Series stepper drives do not attempt to use any power wiring
harness taken from an XL drive. Although the same mating connector is used for
both an XL and a ViX, the ViX wiring is the reverse of the XL and the wrong wiring
connection will damage the drive.
Mating connector type is: Wieland type number 8213B/ . This connector is available in two
forms:
1. Part number 25.323.4053.0 (Parker part number 0405.811)
2. UL marked version with part number 25.323.1053.0

ViX500 6.3A RMS 6600µF
ViX250 2.5A RMS 3300µF
Table 3-2. Drive Supply Currents
+24V Requirements
Both drive types require a +24V controller and logic supply. The supply to each drive should
be fitted with a time-delay fuse, rated at 3A. Note: The +24V supply used must meet the
voltage requirement specification of +24V DC +10% -15%, ripple <1V p-p.
The supply may also be required for an encoder and motor brake.
Absolute voltage range 20 to 27V
Nominal drive current 250mA (excluding encoder & brake)
Extra encoder current 150mA
Extra brake current 500mA
Safety Earth Requirements
Earth the drive using the earth pin on X1 (pin 8). Also earth the power 0V connector on
pin 9.

12 VIX AH SERVO DRIVE USER GUIDE
Power Supply Options
Using the previous section, estimate the power required for a single drive or for a group of
drives. A set of torque curves (Figure 3-2) for various motor/drive combinations can be used
for calculating an applications likely power requirements.
A single axis using a ViX250, or possibly a lightly loaded dual-axis application may be
powered using an XL-PSU. This switching supply has a power rating of 250W and can
supply 3.1A continuous (7.5A peak, depending on supply volts and 24V loading) which could
be used for BE230D medium speed applications.
Higher torque/current requirements will need to use the ViX500 drive and a high current
linear supply, such as the PL1100. Further power supply information is given in
Appendix A.
