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 an installer 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

CHAPTER 1. GENERAL DESCRIPTION 1
Chapter 1. GENERAL DESCRIPTION
Introduction The PK2 bipolar stepper drive is a packaged version of the SD2
model, and has been designed primarily for single-axis applications.
It is suitable for most positioning applications and operates with a
wide range of motors. Incorporated in the drive is a toroidal mains
transformer, and all power supply components necessary for direct
operation from the AC mains supply. There is also an 8-way DIL
switch which enables the drive operating conditions to be
programmed, and a protection circuit guards against short circuits
across or between motor windings (not to ground). Additional
features include an internal oscillator, multi-turn preset controls and
standby circuit.
Two versions are available: PK2/115V and the PK2/230V. It is not
possible to change the voltage setting.
Specification Drive circuit Bipolar chopper-regulated with overload
protection
Switching sequence Full step or half step
Nominal output current 2A/phase (current may be set to lower
value by means of DIL switch)
Drive supply voltage 36v DC
Suitable motor type 4, 6, or 8-lead (5-lead not suitable)
Hybrid or Permanent magnet
Minimum motor inductance 1mH
Nominal chopping freq. 15kHz
Internal oscillator Slow (not ramped) 40-1,000 steps/sec
Speed ranges Fast (ramped) 400-10,000 steps/sec
Acceleration time 60mS
Deceleration time 30mS
These times may be increased by fitting
additional capacitor
Fault output circuit Open-collector NPN transistor
Fault output logic levels Low (transistor switched to 0v) +1v
max. at 25mA max.
High (transistor off) + 24v max.
Input impedance 4K7 pull-up to +12v
