Page 9: Section 1. Introduction
SECTION 1. INTRODUCTION 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...
Page 10 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.
Page 11: Section 2. Getting Started
Section 2. GETTING STARTED What You Should Have Upon receipt, you should inspect your BD-E Series Drive system for obvious damage to its container. Report any damage as soon as possible. The items listed in Table 2-1 should be present and in good condition. To verify that you have the proper drive model, check the model number listed on the drive serial plate.
Page 12 BD SERVO DRIVES USER GUIDE Pre-installation Test This section provides procedures to help you to connect up your BD drive system for a pre- installation test. Please note the pre-installation test allows you to become familiar with the operation of the drive prior to permanent installation, it should only be set up and used by competent personnel familiar with installation of motion control equipment.
Page 13 2. Connecting to an AC Supply The BD-E Series of drives operate direct-on-line from a 220-240V AC input, with no isolating transformer. Please note that the safety earth connection is necessary to provide a return path for the leakage current flowing through line-to-earth capacitors fitted on the internal filter board.
Page 14 BD SERVO DRIVES USER GUIDE The velocity/torque bit switch 5 should be set to OFF (velocity amplifier). Bit switch 6 should be set to OFF, to de-energise the drive. When a link or switch is fitted between pins 5 and 6 of the Drive I/O Connector as shown in Figure 2-2, the drive will be energised.
Page 15: Section 3. Installation
SECTION 3. INSTALLATION Section 3. INSTALLATION Precautions During installation,take the normal precautions against damage caused by electrostatic discharges. Earthed wrist straps should always be worn. Environment The drive system should be installed vertically in an area where there is at least a 50mm air gap all around the package.

Page 18 12 BD SERVO DRIVES USER GUIDE Table 3-1. User I/O Connector Pin Functions User I/O Pin Description The User I/O connector provides access to the main drive control signals. The function of each pin is described below. Pin 1 (V2) & Pin 2 (V1) Input pins 1 and 2 can act as differential analogue torque or velocity inputs, depending upon the state of bit switch 5.
Page 19 SECTION 3. INSTALLATION 13 Pin 4 is drive ground and is linked to mains earth via a high frequency filter. Pin 5 Reset Pin 5 is the reset input, when the input is low, the drive is de-energised. Any latched faults remain latched while the input is low and are reset on the high-going edge.
Page 20 14 BD SERVO DRIVES USER GUIDE Pin 9 Fault Output Pin 9 is an open collector fault output signal which goes low when a fault occurs. The output can be pulled up to a maximum voltage of +28V, and the output transistor can pass a maximum current of 25mA.

Page 24 18 BD SERVO DRIVES USER GUIDE Extending the motor and encoder leads Unless the use of bulkhead connectors is unavoidable, it is preferable to make up entirely new leads rather than to extend the cables supplied, but the same connector types must be used and screens must be correctly terminated.
Page 25 SECTION 3.

ENCODER MOTOR 140mm MINIMUM cables tied together for their entire length EMERGENCY STOP...
Page 26 20 BD SERVO DRIVES USER GUIDE Cable routing The mains cable should have a minimum length of 1 metre and needs to be terminated close to where the mains earth connection is made. The safety earth lead, connected to the stud on the side of the drive, needs to be closely routed with the mains lead.
Page 27 SECTION 3. INSTALLATION 21 Earth leakage current The AC supply to the BD-E drive is internally filtered to achieve EMC compliance. The filter components create an earth leakage current of the order of 10mA, which is compatible with standard residual-current breakers operating at 30mA. The BD-E drive is not suitable for use on supplies employing high-sensitivity RCD breakers.
Page 28 22 BD SERVO DRIVES USER GUIDE Setting Up the Drive Application Types There are two basic types of applications (described below) for the BD servo drive. Each type of application requires a different type of tuning. Velocity Following For this application, it is required that the axis follows programmed velocities as accurately as possible.
Page 29 SECTION 3. INSTALLATION 23 Note: When bit switch 6 is OFF a connection must be made between pins 5 and 6 of the Drive I/O connector to enable the drive. Tuning the BD Drive The appropriate tuning procedure should be carried out on each axis. The procedures in this section assume that you have completed the connection and test procedures provided in Sections 2 and 3.
Page 30 24 BD SERVO DRIVES USER GUIDE Increase the input signal to run the motor at high speed (not full speed) and check for Step 9 - smooth behaviour. If there is excessive noise or vibration, try turning the Time Constant control anti-clockwise.

Page 37: Section 5. Maintenance & Troubleshooting
SECTION 5. MAINTENANCE & TROUBLESHOOTING 31 Section 5. MAINTENANCE & TROUBLESHOOTING Drive Maintenance Routine maintenance is not necessary, but occasional checking of the following points is recommended. Motor Maintenance Periodically check the motor to ensure that no bolts or couplings have become loose during operation, and check the motor cable or leads periodically for signs of wear.
Page 38 32 BD SERVO DRIVES USER GUIDE Protection Circuits The BD Drive has a number of protection circuits which automatically prevent damage ocurring during fault conditions. If a fault does occur it will cause a front panel LED to light up and may de-energise the drive.
Page 39 SECTION 5. MAINTENANCE & TROUBLESHOOTING 33 The overtemperature LED will come on if the drive or motor is operating outside its specified continuous rating, requiring the duty cycle to be reduced. If the motor feedback connector becomes disconnected, the thermal switch will appear to have opened and the drive will de-energise, indicating an overtemperature fault.
Page 40 34 BD SERVO DRIVES USER GUIDE Returning the System Contact the Parker Automation Technology Centre or the machinery manufacturer who supplied the product. Equipment for repair should NOT be returned directly to Digiplan without prior authorisation. Repairs will be carried out by Digiplan but will be processed via your supplier.
Page 41: Appendix A. Encoder Setup
APPENDIX A. ENCODER SETUP 35 Appendix A. ENCODER SETUP Introduction This section is applicable when the BD drive is not used with Digiplan MD Series motors. BD drives are designed to operate with 3-phase brushless servo motors which have both a commutation encoder (Hall effect encoder) and an incremental encoder fitted.
Page 42 36 BD SERVO DRIVES USER GUIDE The DC power supply should be set to provide a current approximately equal to the motor's stall current. This will pull the rotor into the index position. To identify the 'v' or 'w' phase, disconnect one of the diode connected phases, if the motor moves CW the 'v' phase has just been disconnected.
Page 43 APPENDIX A. ENCODER SETUP 37 Commutation Encoder Pull up Voltage The BD drive may be used with the following types of commutation encoders: Open collector outputs (single ended or complementary) TTL outputs (single ended or complementary) Line driver outputs The bit switch 3 selects the pull-up voltage for the commutation encoder inputs: Function Switch 3 Inputs pulled up to +15V...
Page 44 38 BD SERVO DRIVES USER GUIDE Polarity of the 'Reset' Input The reset input circuit can be configured as a normally open (pull-up) or a normally closed (pull- down) input, as shown in Figure A-3. Bit switch 6 OFF (Pull down) N.C.
Page 45 APPENDIX A. ENCODER SETUP 39 Current Limit Bit switches 7 and 8 are used to set the peak motor current as follows: BD75E Current Limit BD150E Current Limit Switch 7 Switch 8 6.0A 12.0A 4.2A 8.5A 3.0A 6.0A 2.5A 5.0A The minimum current setting should be used for tuning the drive.
