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. 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.
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 it 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.
A permanent mains safety earth connection must be made to the earth terminal on the front of the drive
case before applying mains power.
If the equipment is used in any manner that does not conform to the instructions given in this manual , then the
protection provided by the equipment may be impaired.
EMC INFORMATION
EMC Information is presented in boxed paragraphs (such as this one). Digiplan cannot guarantee compliance
unless guidelines are strictly followed.

User Guide Change Summary
The following is a summary of the primary changes to this user guide since the last version was
released.
When a user guide is updated, the new or changed text is differentiated with a change bar in
the outside margin (this paragraph is an example). If an entire chapter is changed, the change
bar is located on the outside margin of the chapter title.

SECTION 1. INTRODUCTION 1
Section 1. INTRODUCTION
Product Description
The BD-E Series of EMC and LVD compliant brushless velocity/torque drives are capable of
operating direct-on-line from a 220-240V AC input, with no isolating transformer. A choice of two
current ratings are available:
BD150E/230V 6A RMS continuous (12A RMS peak)
BD75E/230V 3A RMS continuous (6A RMS peak)
Both drive types have high resolution sinusoidal commutation and have been designed to be
used with three phase brushless servo motors. Control of either velocity or torque is provided via
a ±10V analogue input.
The drives are equipped with multiple protection circuits which guard against output short circuits
and excessive current output over long time periods or at low speed operation. Further circuits
protect against overspeed operation, commutation loss, motor feedback loss, overvoltage,
undervoltage, supply failure and overtemperature faults.

LEDs
HV Present LED (Green)
This LED indicates that the DC bus voltage is present, but it does not necessarily mean that the
logic supplies are correct.
Warning - Risk of Electric Shock
When power is removed, the drive terminals should not be touched while the
green LED remains alight.
SECTION 1. INTRODUCTION 3
Current Limit LED (Yellow)
Illumination of this LED indicates that the current demand is exceeding the drives maximum
programmed current, and is therefore clamped. For adjustment of the current limit level, see the
current limit bit-switch setting sub-section.
IT Clamp LED (yellow)
The illumination of this LED indicates that the drive has been set to demand too much peak
current for too long a time, causing the current limit to be reduced to 6.8A RMS for the
BD150E/230V (3.4A RMS for the BD75E/230V) to protect the drive.
Overtemperature LED (Red)
Illumination of this LED indicates that either the drive or motor is operating outside its specified
continuous temperature rating, requiring extra cooling to be used or reduction of the operating
duty cycle.
Note: the over temperature LED will also be illuminated by faulty motor feedback connections.
For more information refer to the Maintenance and Troubleshooting Section.
Drive Fault LED (Red)
This LED indicates one of the following fault conditions:
• Overvoltage
• Undervoltage
• Supply failure
• Overcurrent
• Overspeed
For more information refer to the Maintenance and Troubleshooting Section.
HV Present
This LED indicates that a voltage is present on the High Voltage capacitors.
Internal Commutation LEDs
Three diagnostic/set-up LEDs are present within the drive, but can be observed through the
ventilation slots on top of the drive towards the front panel face. From the front panel face the
LEDs are:
Red Overcurrent
Yellow Index
Yellow Commutation
4 BD SERVO DRIVES USER GUIDE
The index LED is illuminated when the index pulse is high and the commutation LED lights when
the A channel of the commutation encoder (Com A+) is high. For more information refer to the
Commutation sub-section. The red overcurrent LED provides greater diagnostic information
under drive fault conditions.
Potentiometers
Balance
This 20 turn potentiometer is used to adjust the balance of the amplifier to give zero motor
current when there is no velocity input demand.
Tach Gain
The level of the velocity feedback is adjusted by this 20 turn potentiometer. For settings see the
Installation section.
Time Constant
The Time Constant single turn potentiometer and associated components determine the
bandwidth of the amplifier. For settings see the Installation section.
Damping
This single turn potentiometer adjusts the response characteristic of the amplifier so that the axis
achieves the demanded velocity without overshoot. For settings see the Installation section.
Bit Switch
All drive options are selected by the front panel bit switch, there are no internal links or
adjustments within the drive.
The bit switch selects the following functions:
Bit Switch Number Function
1, 2 Motor pole number
3 Commutation encoder pull-up selection
4 Encoder resolution
5 Velocity/Torque selection
6 Reset pull-up/pull-down
7, 8 Current limit
