1. Introduction

Product Description

Available in two current ratings, these microstepper indexer drives employ an optimised
digital field oriented current loop to provide low speed smoothness coupled with high speed
torque. Advanced digital techniques result in reduced settling time and reduced mid speed
instability when compared with similar competitive drive types.

The common use of EASI-V programming language and similar supply requirements make
this drive ideal for mixed technology applications when used with the ViX digital servo.

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. For DIN rail mounting, see the thermal limitations
statement in Drive Mounting Options.

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 stepper 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 8213B/10 F OB, Part number 25.323.4053.0 (Parker part
number 0405.811).

PL1100 Power Supply

General Description

The PL1100 is a linear power supply with a rated output of 1120W (80V/14A) for use with
ViX and XL series drives. The supply requires a suitably rated transformer supplying 50V
AC RMS for the HV and 20V AC RMS for the +24V DC. The use of the PL1100 offers the
following benefits:

• Provides 80V HV and +24V DC output

• Single or three phase operation

• Built-in power dump switch

• Integral fusing

Figure 3-4 shows the PL1100 output wiring for two ViX drives. This illustrates how to route
the main HV supply separately to each drive. The lower current requirements of the +24V
logic/brake supply can allow the wiring to be linked between drives.

For full installation instructions see the PL1100 Power Supply leaflet 1600.323.XX.

EMC Installation

These EMC installation recommendations are based on the expertise acquired during the
development of compliant applications, which Parker believes are typical of the way, a drive
or drives may be used. Provided you have no special installation requirements or untypical
operating environment requirements, ViX drives will conform to current EMC Directives, as
defined at the front of this user guide.

General Requirements

ViX mounted drives, unless used with an XL-PSU, will require an EMC supply filter to meet
EMC installation compliance requirements. Mount the drive on a conductive panel which is
shared with the EMC filters. If the panel has a paint finish, it will be necessary to remove the
paint in certain areas to ensure filters and drive make a good large-area metal to metal
contact between filter case and panel.

Mount filters close to the drive and keep the supply wiring as short as practical. Attempt to
layout the wiring in a way that minimises cross coupling between filtered and non-filtered
conductors. This means avoiding running wires from the output of a filter close to those
connected to its input. Where you wish to minimise the cross coupling between wires avoid
running them side-by-side one another, if they must cross, cross them at 90° to each other.
Keep wiring supported and close to cabinet metalwork.

Recommended EMC filter types are CORCOM 6FC10 for loads up to 6A and 3VK1 for the
+24V supply up to 3A. Multi-axis systems may require higher current rated filters.

+24V Supply Connections

ViX drives not using an XL-PSU will require a logic supply of +24V DC at 250mA (nominal)
per drive. The +24V powers the controller and I/O circuits. Keeping the +24V independent
of the drive’s internal high voltage bus supply allows the option of keeping the I/O and
controller active when no main supply is present.

Connect the +24V supply to X1 pin7 and the return to X1 pin6, the total wire length, from
supply to drive, must not exceed 10m.

Connect the +24V supply 0V line to system earth (0V) at some convenient point before the
EMC filter input, as shown in the recommended EMC layout diagram, Figure 3-5.

The 24V 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.

Motor Connections to the Drive

The recommended wire size for ViX250IM/500IM motor cables, of length less than 20m, is
1mm2. For motor cable lengths greater than 20m (up to a maximum of 50m) use a wire size
of 2.5mm

34805), the green wire being used to provide an earth return to the drive. Termination at the
motor must be made using a 360° bond to the motor body, and this may be achieved by
using a suitable clamp. Many stepper motors are designed to accommodate an appropriate
terminal gland which can be used for this purpose.

At the drive end of the cable, a 360° connection to the screen should be made using the
P-clip provided beneath the motor connector. The P-clip needs to be firmly clamped to the
copper braid. If the connection appears loose, fold the braid back on itself to increase the
amount of braid under the clip and re-tighten.

Custom cables will require the cable insulation to be removed to expose the braided screen.
If you are using a motor cable with 2.5mm
9mm to accommodate the increased cable diameter. A ferrite absorber, with a specification
matching that of the Chomerics H8FE-1115-NC, is also required to be positioned on the
motor cable using heat shrink sleeving or cable ties. The position of the absorber should be
within 150mm of the drive. Always secure the cable using the P-clip, as shown. Do not rely
upon the connector alone holding the motor cable in place. Avoid stress on the X1

connector by hanging cables, as this may lead to connector over-heating.

Table 3-3. P Clip sizes

Three different size ‘P’ clips allow the use of a variety of motor power cables from different
manufactures.

There must be no break in the 360° coverage that the screen provides around the cable
conductors. If a connector must be used it should retain the 360° coverage, possibly by the
use of an additional metallic casing where it passes through the bulkhead of the enclosure.
The cable screen must not be bonded to the cabinet at the point of entry. Its function is to
return high-frequency chopping current back to the drive. This may require mounting the
connector on a sub-panel insulated from the main cabinet, or using a connector having an
internal screen which is insulated from the connector housing. Within the cabinet itself, all
the motor cables should lie in the same trunking as far as possible. They must be kept
separate from any low-level control signal cables. This applies particularly where the control
cables are unscreened and run close to the drive.

20 VIX IM MICROSTEPPER INDEXER DRIVE USER GUIDE

Note that the motor cable routing within the equipment cabinet should be kept at least
300mm away from I/O cables carrying control signals.

All motor connections must be made using a high quality braided-screen cable. Cables
using a metallised plastic bandage for an earth screen are unsuitable and in fact provide
very little screening. Care must be taken when terminating the cable screen, the screen
itself is comparatively fragile; bending it round a tight radius can seriously affect the
screening performance. The selected cable must have a temperature rating which is
adequate for the expected operating temperature of the motor case.

Motor Cables

Motor cables may be ordered using the part numbers listed in Table 3-4.

Motor Phase Contactors

We recommend that motor phase contactors are not used within the motor power cables. As
an alternative, make use of the drive’s power stage ‘enable’ control signal.

Ferrite absorber specifications

The absorbers described in these installation instructions use a low-grade ferrite material
that has high losses at radio frequencies. They therefore act like a high impedance in this
waveband. Produced by Parker Chomerics, the recommended component is suitable for use
with cable having an outside diameter up to 10mm. The specification is as follows:
Chomerics part number H8FE-1115-NC (Parker part number 0313.020)
Outside diameter 17.5mm
Inside diameter 10.7mm
Length 28.5mm
Impedance at 25MHz 80 ohm
Impedance at 100MHz 120ohm
Curie temperature 130°C (the device should not be operated near this temperature)

Motor Selection

Usually optimum performance will be obtained when the current rating of the motor is
between 1 and 1.5 times the drive rating. Drives can be de-rated to accommodate motors
with lower current ratings (using variable MC within the MOTOR command), however the
high speed torque will be reduced.

Do not use a drive setting which gives an output current greater than the motor rating.

With 4 lead motors the bipolar rating is quoted and this should match the criteria stated
above.

With 8 lead motors the bipolar rating of the motor, which is normally quoted, refers to a
parallel winding connection. With the windings connected in series the current rating of the
motor connection will be 50% that of the bipolar rating, and the motor will give improved low­speed torque, but reduced high-speed torque.

The ViX250IM/ViX500IM will drive motors having an inductance as low as 0.5mH and as
high as 20mH, but the recommended motor inductance range is between 0.8mH and 10mH.

Performance of the ViX250/ViX500IM is optimised for the following motor types, listed in
Table 3-5.

Motor Voltage Ratings

Motors with a withstand voltage rating from phase to earth of 1000V AC should be used. An
insulation withstand rating of 500V AC is acceptable if an isolating transformer with earthed
screen is used to power the system, and 0V input is earthed, as specified.

Large Motors

The largest recommended motor size is a 34-frame 3-stack. Please contact Parker if
you wish to use a larger frame motor.

Motor Connections at the Motor

Motor connections should be made directly between the drive and motor, the use of any
switching devices, such as contactors is not recommended.

In the majority of applications the drive will be used with an eight lead motor with the
windings connected in parallel or series, as shown in Figure 3-6. Motor connections will
need to be determined from the motors data sheet or Appendix B. These are normally
identified by wire colour or terminal markings, depending upon the make of the motor.
