IMPORTANT INFORMATION FOR USERS
Installation and Operation of Digiplan Equipment
It is important that Digiplan motion control equipment is installed and operated in such a way that all applicable
safety requirements are met. Note that it may be necessary for the completed installation to comply with the Low
Voltage Directive or Machinery Directive. It is your responsibility as a user to ensure that you identify the relevant
safety standards and comply with them; failure to do so may result in damage to equipment and personal injury. In
particular, you should study the contents of this user guide carefully before installing or operating the equipment.
The installation, set-up, test and maintenance procedures given in this User Guide should only be carried out by
competent personnel trained in the installation of electronic equipment. Such personnel should be aware of the
potential electrical and mechanical hazards associated with mains-powered motion control equipment - please see
the safety warning below. The individual or group having overall responsibility for this equipment must ensure that
operators are adequately trained.
Under no circumstances will the suppliers of the equipment be liable for any incidental, consequential or special
damages of any kind whatsoever, including but not limited to lost profits arising from or in any way connected with
the use of the equipment or this user guide.
!
SAFETY WARNING
High-performance motion control equipment is capable of producing rapid movement and very high forces.
Unexpected motion may occur especially during the development of controller programs. KEEP WELL CLEAR of
any machinery driven by stepper or servo motors. Never touch any part of the equipment while it is in operation.
This product is sold as a motion control component to be installed in a complete system using good engineering
practice. Care must be taken to ensure that the product is installed and used in a safe manner according to local
safety laws and regulations. In particular, the product must be enclosed such that no part is accessible while power
may be applied.
If the equipment is used in any manner that does not conform to the instructions given in this User Guide, then the
protection provided by the equipment may be impaired.
The information in this user guide, including any apparatus, methods, techniques, and concepts described herein,
are the proprietary property of Parker Digiplan or its licensors, and may not be copied, disclosed, or used for any

Selection
The PKC60M/80M Packaged Drive is supplied with its supply voltage
selector set to 230V, as shown below.
115V 230V
AC SUPPLY
VOLTAGE
115V AC operation can be set by adjustment of the supply selector,
which is positioned by the supply input connector (see Mains Supply
in Installation ).
Note: No change of fuse is required between 230V and 115V
operation.
Supply Cable The drive is supplied with two mains supply cables:
IEC connector to an American style 3-pin plug - for use at 115V
IEC connector to flying leads - for use at 230V or 115V.
Factory
Jumper Link
Settings
The PKC Series uses CD60M/CD80M drives which are configured by
jumper link settings. As supplied from the factory, the link settings will
give the following drive performance:
Standby current reduction 50% of full load
Drive resolution 400 steps/rev
Energise permanently enabled
Motor current set to a minimum
To alter any of these settings refer to Chapter 3 Setting Up The
CD60/80M Drive.

CHAPTER 1. GENERAL DESCRIPTION 1
Chapter 1. GENERAL DESCRIPTION
Introduction The PKC series drives are packaged versions of the CD60/80M
models designed to operate directly from either 115v or 230v AC
mains supplies*. The built-in toroidal transformer will deliver a motor
supply voltage of either 85v or 55v DC, the lower voltage being
preferable in low-speed applications in order to minimise dissipation
in both motor and drive. A power dump circuit is incorporated which
dissipates regenerated power during deceleration of the motor.
Other features include full short-circuit and thermal protection,
programmable motor current fold-back at standstill, and
ministepping. Resolutions of 4000, 2000, 1000 or 400 steps/rev are
available.
A simple ramped oscillator is incorporated in the drive and this has
two speed ranges with preset speed controls. External speed
controls may be fitted if required. The slow speed may be set
between 400 and 10,000 steps/sec., and the fast speed between
4,000 and 100,000 steps/sec. The fast range is ramped with an
approximate acceleration time of 120mS and a deceleration time of
60mS. These times may be extended by the addition of a capacitor.
The PKC drives have provision for a BC7 buffered clock or RC9
ramped clock card to be fitted, and this will operate entirely
independently of the built-in oscillator. The drives can also be used
in conjunction with Digiplan or Compumotor packaged indexers; in
this case an OPT2 opto card will be required to provide isolation
between the control system and the drive.
The PKC drive may also be fitted with an IFX indexer card. This
version is covered by a separate user guide.
There are six drives in the range and are numbered according to the
corresponding CD drive module and the options that are fitted. The
drive types are:
PKC60M PKC80M
PKC60M/RC9 PKC80M/RC9
PKC60M/BC7 PKC80M/BC7

2 PKC SERIES PACKAGED STEPPER DRIVES USER GUIDE
Note: Previous versions of the PKC used to incorporate
CD20/25/25M/30/35/35M drives. CD60/80M drives offer
ministepping as standard, and the CD80M offers higher current. The
former boost input is now external reset. The mains input to the
PKC is now via an IEC connector, and a mains voltage selector is
provided.
* The drive is ordered as a 115V or 230V model, but can be changed
to suit local requirements by altering the voltage selector.
