Installing Your 8720MC Drive
Before Mounting Your
System
Before you mount your 8720MC system make sure you understand the following:
• How to unpack the system
• System mounting requirements
• Ventilation requirements
• How to size an enclosure
• How to select fuses
Unpacking Your 8720MC
Remove all packing material, wedges, and braces from within and around the components. After unpacking, check the item(s) name plate catalog number against the purchase order.
Each 8720MC drive ships with the following:
• One 8720MC drive
• One bag of connectors for feedback and I/O connections
• One installation manual (publication 8720MC-IN001x-EN-P)
IMPORTANT
Some of the mounting and wiring information is specific to the individual frame sizes. If you do not know what your frame size is, refer to
Publication 8720MC-IN001D-EN-P — December 2002
Installing Your 8720MC Drive 1-7
System Mounting Requirements
There are several things that you need to take into account when preparing to mount the 8720MC:
• The 8720MC must be enclosed in a grounded conductive enclosure offering protection as defined in standard EN 60529
(IEC 529) to IP55 such that they are not accessible to an operator or unskilled person, in order to comply with UL
and CE requirements. A NEMA 4X enclosure exceeds these requirements providing protection to IP66.
• The ambient temperature of the enclosure in which you install the
8720MC must not exceed 50° C (122° F).
• The panel you install inside the enclosure for mounting your system components must be on a flat, rigid, vertical surface that won’t be subjected to shock, vibration, moisture, oil mist, dust, or corrosive vapors.
• You need to maintain minimum clearances (refer to Figure 1.3) for
proper airflow, easy module access, and proper cable bend radius.
• The 8720MC can operate at elevations to 1000 m (3280 ft) without derating, however, the continuous current rating must be de-rated by 3% for each additional 300 m (984 ft) up to 3000 m (9842 ft).
Consult your local Allen-Bradley representative prior to operating above 3000 m (9842 ft).
ATTENTION
!
Plan the installation of your system so that you can perform all cutting, drilling, tapping, and welding with the system removed from the enclosure.
Because the system is of the open type construction, be careful to keep any metal debris from falling into it. Metal debris or other foreign matter can become lodged in the circuitry, which can result in damage to components.
Refer to Appendix A for mounting dimensions, power dissipation, and
environmental specifications for the 8720MC.

Installing Your 8720MC Drive 1-9
Sizing an Enclosure
If you are supplying your own enclosure for the 8720MC drive, you can mount your drive within an enclosure or you can mount the drive and let the heat sink extend outside the enclosure.
With no active method of heat dissipation (such as fans or air conditioning) either of the following approximate equations can be used:
Metric Standard English
A
=
1.8T – 1.1
A
= ----------------
T
– 1.1
Where T is temperature difference between inside air and outside ambient (°C), Q is heat generated in enclosure (Watts), and A is enclosure surface area (m²). The exterior surface of all six sides of an enclosure is calculated as
A = 2dw + 2dh + 2wh
Where d (depth), w (width), and h (height) are in meters.
Where T is temperature difference between inside air and outside ambient (°F), Q is heat generated in enclosure (Watts), and A is enclosure surface area (ft²). The exterior surface of all six sides of an enclosure is calculated as
A = (2dw + 2dh + 2wh) / 144
Where d (depth), w (width), and h (height) are in inches.
Contact your cabinet manufacturer for options available to cool your
cabinet. Refer to Power Dissipation Specifications in Appendix A.

Installing Your 8720MC Drive
Fuse Selection
This section describes the fuse requirements for your 8720MC system.
The 8720MC utilizes internal short circuit output protection and is suitable for use on a circuit capable of delivering up to 100,000 amperes, when protected by class CC, J, L, and R fuses. Circuit breakers with adequate widthstand and interrupt ratings, as defined in
NEC 2002, article 110.9 and 110.10, are also allowed. Overcurrent protection must be adequately coordinated per NEC 2002, article 240.
The 8720MC is listed by Underwriters Laboratories, Inc. with fuses
sized (FLA), according to UL 508C. Refer to Fuse Specifications in
Appendix A for recommended fuses.
In most cases, fuses selected to match the drive input current rating will meet the NEC requirements and provide the full drive capabilities.
Dual element, time delay (slow acting) fuses should be used to avoid nuisance trips during the inrush current of power initialization. Refer
to Power Specifications in Appendix A for input current specifications
for your 8720MC.
AC Input Fusing (380-460V ac)
The 8720MC AC input drives (8720MC-B021, -B027, -B034, -B042, and
-B048) are suitable for use in circuits that can deliver up to a maximum of 70 rms amperes when used with the AC input line fuses
The 8720MC AC input drives do not contain input power short circuit fusing. For the recommended size and type specifications for fuses
necessary to protect against short circuits, refer to AC Input Line Fuse
Ratings (380 to 460V ac Input) on page A-3.
Blower Motor Fusing
Protect all 8720SM motor fans with the use of 1A, time delayed, current limiting fuses. Bussmann™ fuse (LP-CC-1) is recommended.
Refer to Appendix B for the 8720MC drive interconnect diagrams.
Publication 8720MC-IN001D-EN-P — December 2002
Installing Your 8720MC Drive 1-11
8720MC-RPS Fusing
The 8720MC DC input drives (8720MC-Bxxx and -Dxxx) are suitable for use in circuits that can deliver up to a maximum of 250 rms symmetrical motor amperes when used with the 8720MC-RPS and the
AC input line fuses specified in 600V ac Input Fuse Specifications on page A-4.
When two or three 8720MC-RPS065 Regenerative Power Supplies are operating in a master/slave mode, the output load is shared equally between the power supplies. When a master and one slave is required input fuses and wire should be sized to 1/2 of the total required maximum continuous input current for the total required drive load, multiplied by 1.75. When a master and two slaves are required input fuses and wire should be sized to 1/3 of the total required maximum continuous input current for the total required drive load, multiplied by 1.75.
Refer to Appendix B for the 8720MC drive with 8720MC-RPS interconnect diagrams. For more information on the 8720MC-RPS
Regenerative Power Supply, refer to the 8720MC Regenerative Power
Supply User Manual (publication 8720MC-RM001x-US-P).
DC Input Fusing (750V dc)
When multiple drives and/or master/slave RPS units are needed to meet the load requirements a common bus architecture is preferred.
For common bus applications Allen-Bradley’s Bulletin 140 bus bar and panel mounting components are recommended. Size the bus bar capacity to at least 175% of total RPS continuous output current. The
DC input wire and fuses to each drive should be sized to 175% of each drives’ maximum continuous input current requirements.
All fuses on the DC bus must be rated for 1,000V dc operation. For DC bus fuses use Gould A1-100P, Gould A100C (80 amps and higher) or equal. Refer to the 8720MC Regenerative Power Supply User Manual
(publication 8720MC-RM001x-US-P) for master/slave RPS configurations.
When a single RPS is matched to a single drive, DC drive input fuses are not required. The following table is used to select DC drive input fuses and assumes more than one drive is connected to the RPS common bus, otherwise DC drive input fuses are not required.
Suggested wire sizes assume single conductor connections. It is perfectly acceptable to use 2 or 3 conductors in parallel as long as the total amperage requirements are met. For example 2 parallel #12 conductors could be used in place of a single # 10 conductor.
Refer to 1000V dc Input Fuse Specifications on page A-5 and
Appendix B for interconnect diagrams.

HF Bonding Your System
Bonding is the practice of connecting metal chassis, assemblies, frames, shields and enclosures to reduce the effects of electromagnetic interference (EMI). For more information on the concept of high-frequency (HF) bonding, the ground plane principle, and electrical noise reduction, refer to System Design for Control of
Electrical Noise (publication GMC-RM001x-EN-P).
Bonding Modules
Unless specified, most paints are not conductive and they act as insulators. To achieve a good bond between the drive and the subpanel, surfaces need to be paint-free or plated. Bonding metal surfaces creates a low-impedance return path for high-frequency energy.
IMPORTANT
To improve the bond between the drive and subpanel, construct your subpanel out of zinc plated
(paint-free) steel.
Improper bonding blocks the direct return path and allows high-frequency energy to travel elsewhere in the cabinet. Excessive high-frequency energy can effect the operation of other microprocessor controlled equipment.

Bonding Multiple Subpanels
Bonding multiple subpanels creates a common low impedance exit path for the high frequency energy inside the cabinet. Subpanels that are not bonded together may not share a common low impedance path. This difference in impedance may affect networks and other devices that span multiple panels. Refer to the figure below for recommended bonding practices.
Figure 1.5
Multiple Subpanels and Cabinet
Recommended:
Bond the top and bottom of each subpanel to the cabinet using
25.4 mm (1.0 in.) by 6.35 mm (0.25 in.) wire braid.

Mounting Guidelines to Reduce Electrical Noise
When mounting AC input components or an external active shunt module refer to the sections below for guidelines designed to reduce system failures caused by excessive electrical noise.
AC Line Filters
Observe the following guidelines when mounting your AC line (EMC)
filter (refer to figures 1.6 and 1.7 for examples).
• Mount the AC line filter on the same panel as the 8720MC and as close to the 8720MC as possible.
• Good HF bonding to the panel is critical. For painted panels, refer
• AC input power cable between the AC line filter and 8720MC must be shielded if it enters a wireway.
• Segregate input and output wiring as far as possible.
IMPORTANT
CE test certification applies only to AC line filter and single 8720MC drive. Multiple drive loads may perform satisfactorily, but the user takes legal responsibility.
Line Reactor, Harmonic Filter, and Varistor
All the guidelines that apply to AC line filters also apply to the line reactor, harmonic filter, and varistor. These components only apply to common bus configurations.

External Active Shunt Module
Observe the following guidelines when mounting your external active shunt module (1336-MOD-KBxxx) outside the enclosure. Refer to
• Mount circuit components and wiring in the very dirty zone or in an external shielded enclosure (as shown in the figure below)
• Run shunt power and fan wiring inside metal conduit to minimize the effects of EMI and RFI
• Keep unshielded wiring as short as possible

When mounting your active shunt module inside the enclosure,
follow these additional guidelines (refer to Figure 1.10 for an
example).
• Metal-clad modules can be mounted anywhere in the dirty zone, but as close to the 8720MC as possible
• Shunt power wires can be run with motor power cables.
• Separate shunt power cables from other sensitive, low voltage signal cables.

Understanding I/O
Specifications
8720MC Connector Data
A description of the 8720MC input/output is provided on the following pages.
2-11
Digital Inputs and Outputs
The 8720MC High Performance Drives support 10 digital inputs, 4 relay contact outputs and 6 digital outputs.
These are sinking inputs that require a sourcing device. A 24V power and common connection is provided for use with the inputs.
IMPORTANT
To improve registration input EMC performance, refer to the System Design for Control of Electrical
Noise Reference Manual (GMC-RM001x-EN-P).
Digital Input Power
The isolated +24V dc power available from the 8720MC is limited to
120 mA and is adequate for use with the 10 digital inputs but may be inadequate when the full set of 6 digital outputs are used. Keep current requirements below 120 mA (total) when using the 8720MC isolated +24V dc power for digital I/O. If more than 120 mA is required, provide an external (+24V dc) power supply.
Digital Inputs
Digital input specifications for SERCOS drives are shown in the table below. These inputs are optically isolated to 500V from control power.
They have hardware filtering with a time constant and a software debounce, which requires stable input prior to validation. Values are shown in the table below. A description of these signals is provided

8720MC Connector Data
Default Digital Input Descriptions
Drive Enable - The drive enable input is used to inform the drive that the regenerative power supply and the motion controller are ready for the drive to follow the auto or jog reference command. When the drive is enabled the drive will apply torque to the motor as directed by the reference commands (with no internal drive shut down faults).
The drive will come to a regen stop when the enable is removed.
Drive Error Reset Request - If a drive shut down fault has occurred, setting the Drive_Err_Reset bit is required in order to reset the fault.
The fault cannot be reset unless the drive is disabled and the fault condition is removed. A transition from low to high is required to reset a drive shut down error. Power cycling also resets the drive error.
Parameter Set Select bit 0, 1 and 2 - Setting these 3 binary bits determines which parameter set is in use and /or which motor winding (high or low) is selected. The choices are:
000 = low 0, 001 = low 1, 010 = low 2, 011 = low 3
100 = high 0, 101 = high 1, 110 = high 2. 111 = high 3
When any or all of the 3 bits change and remain changed for a 50 ms filter delay the new parameter set will be enabled.
Orient Request - When the Orient Request bit (parameter 152) is set, an orient will be initiated as determined by Auto Home (parameter
582). In addition the orient parameters 153, orient angle, 154, orient options, 222, orient speed, and 260, positioning acc/dec rate, will be used to characterize the orient move. The orient will terminate when the motor reaches the orient position and the orient complete status bit is set. The drive is placed in positioning mode in order to execute the orient. If holding torque is required after the orient position is achieved, then the orient request must be maintained even if the orient complete output is set. The drive will ignore the reference and hold position until the orient request is removed. The orient can be initiated when the motor is rotating or stationary.

Manual/Auto Select - When the manual mode bit is set true, the manual mode is selected. In this mode the drive can be operated from an Internal HIM, an external HIM or a SCANport™ connected PLC™ via the jog reference and jog bit or the digital interface via analog input 2 (P1-16) and the jog digital input. In auto mode only the configured auto command reference is followed by the drive.
Whenever the drive is switched from auto to manual the drive will come to a regenerative stop. It will follow the jog reference from the source that is providing the jog request. If the drive is switched from manual to auto, the drive will also come to a regenerative stop. A positive transition on the drive enable input from 0 to +24V dc is required to restore auto operation of the drive where the drive follows the auto reference command.
Jog Request - When the drive is enabled in manual mode with no drive faults and the jog command bit on digital input 6 (P5-34) is set true, the drive will respond to the jog reference, Analog Input 2
(P1-16, -17).
Since jog is a momentary function, the drive will continue to follow the reference until the jog is released. When the jog input is released, the motor will regenerate to a stop.
Regen Power Supply OK - Input 10 (P5-36) is used to interface to the 8720MC - RPS fault output. This is a normally open contact which is closed when there are no RPS faults. Since a high is required on this input it must be tied to +24V dc when the regenerative converter is not used. The external active shunt (thermal switch) can also wire to
this input. Refer to figures B.4 and B.5 in Appendix B for examples.
Digital input specifications are shown in the table below. Refer to

Registration Inputs
The 8720MC provides 2 registration inputs. One input is for +24V dc operation and one is for +5V dc operation. The 8720MC can provide
+5V dc or +24V dc to be used with a switch type registration or orient sensor. Both registration inputs can be used in a given application.
From a software perspective the registration inputs are used by the
8720MC software to capture a position within one microsecond of a closure of the registration sensor. This can be used by the drive for orienting to a registration sensor or used by a SERCOS motion controller for probing or position registration. With a SERCOS motion controller the registered position is returned to the motion controller via the SERCOS link as a result of a Registration Procedure.
Input Power
The registration inputs are isolated and can use either the 8720MC
+5V dc or +24V dc power or customer supplied external +5V dc or
+24V dc. Figure 2.11 shows the connections required for the sensor
inputs when internal dc power is used. Terminals P4-4 and P4-8 provide isolated +5V dc power for use with the +5V dc registration inputs and the A quad B output. This power is limited to 250 mA at 5V dc +/- 10%.

Digital Outputs
Six discrete solid state DC current sourcing outputs are available in the
8720MC Drive. These outputs are optically isolated to 500V from control power. Considering the limitation of 120 mA (total) at 24V dc of the 8720MC 24V dc power supply, all power to the 24V dc digital
I/O should be, in most cases, provided externally by the user.
Default Digital Output Descriptions
Zero Speed - Parameter 124 is used to determine the zero speed window. When the motor velocity falls within the configured zero speed window for 50 ms, the zero speed output is set true.
Shut Down Fault - Parameter 11 contains a bit pattern which describes a set of different conditions which can initiate a shut down fault. When any of these conditions exist, the Shut Down Fault output will be true. Selection of parameter 11 in display mode via the HIM or
DriveExplorer™ will allow access to a 16 character display describing the fault.
Auto Reference Enabled - Parameter 529 (P00029) is an event link which indicates that there are no drive faults, the drive is enabled in auto mode, and capable of following the auto reference. This event has a default link to both the digital interface and the SCANport Logic
Status Word.
Orient complete - When an orient is initiated and the orient position is achieved, the drive will enter an orient position achieved state. The
Orient Complete output is used to indicate to the motion controller that the orient position achieved state is established. The orient complete output is turned off when the motor leaves the orient position.
Torque
≥ Torque Limit - Parameters 82 and 83 are configuration parameters which establish the + and - torque limits for the application. There are 8 sets of torque limits since they are part of the servo parameter sets. If any of these torque limits are reached or exceeded, the Torque
≥ Torque Limit Output is enabled. Use
Parameter 520 to determine the source of the torque limit
At Speed - Parameter 157 is a configuration parameter which establishes the At Speed Window. When the velocity error represented by the difference between the commanded velocity and the feedback velocity is less than parameter 157, the At Speed output is enabled.

Drive OK - When the drive is clear of all shut down faults, the Drive
OK contact is closed. The drive does not have to be enabled to be in the drive ok state. This normally open contact is available for use in the motion controller control stop string. The contact is closed when there are no faults.
Enable Brake Solenoid - This output contact is used to interface to a brake solenoid. The contact closes immediately after the drive enable is applied. The drive will apply zero speed holding torque for a configurable on delay time period after the drive has been enabled
(parameter 206). This assures that there is holding torque available while the brake is being released. An additional off time delay is provided (parameter 207). The brake contact will open after a configurable time delay period (parameter 207) from when the drive enable input is removed. The drive will remain enabled for the off delay period to provide regenerative braking until the motor is at zero speed.
High Winding Select - When bit 2 of the parameter set binary code is set to 1 the High Winding Select contact is closed. When interfaced to a contactor, this output is used to select the high motor winding.
This contact is closed only when the low contact output is open.
Low Winding Select - When bit 2 of the parameter set binary code is set to 0, the Low Winding Select contact is closed. When interfaced to a contactor this output is used to select the Low motor winding. This contact is closed only when the High contact output is open.

A quad B Virtual Encoder Output
A virtual 1024 line encoder output interface is provided for use with any motion controller which provides an analog velocity or torque command and expects a 5V TTL A quad B signal from the motor. The quadrature outputs are connected to P5-1, P5-2, P5-3, P5-19, P5-20
and P5-21, as shown in Appendix B.
Figure 2.19 shows the exact nature of the A quad B signals. If the
quadrature output signals are required, the SNS-60 (8720SM S3, S4)
Sincoder must be the 8720SM motor feedback device. The marker from this feedback device has a random width from encoder to encoder. The edge rise is repeatable for any given encoder. This feedback device is best suited for uni-directional homing and referencing. The 8720MC provides the 5V dc power required to drive the signals. Connect the motion controller encoder ground terminal to the P5-4 terminal (ACOM). This assures that the signals are properly referenced to the motion controller encoder ground. The motion controller will count square wave edges and will achieve a 4096 count per turn resolution.

Encoder Power
The motor and auxiliary feedback port connector (P1) provides terminals for both 5V dc and 9V dc encoder power. The encoder voltage used is determined by the feedback device selected (refer to
the table on page 2-23 for a list of feedback devices and their required
input voltages). The standard 8720SM and MP-Series (460V) motor
Stegmann feedback devices use 9V dc encoder power. A total of 300 mA of 5V dc encoder current is shared between the two 5V dc encoder power terminals, P1-7 and P1-20. In a like manner, a total of
300 mA of 9V dc encoder current is shared between the two 9V dc
encoder power terminals, P1-6 and P1-19. Refer to 8720MC Connector

Connecting Your 8720MC
Understanding Basic
Wiring Requirements
This section contains basic wiring information for the 8720MC.
ATTENTION
!
Plan the installation of your system so that you can perform all cutting, drilling, tapping, and welding with the system removed from the enclosure.
Because the system is of the open type construction, be careful to keep any metal debris from falling into it. Metal debris or other foreign matter can become lodged in the circuitry, which can result in damage to components.
IMPORTANT
This section contains common PWM servo system wiring configurations, size, and practices that can be used in a majority of applications. National Electrical
Code, local electrical codes, special operating temperatures, duty cycles, or system configurations take precedence over the values and methods provided.
ATTENTION
!
You are responsible for conforming with the National
Electrical Code (NEC) and all other applicable local codes, wiring practices, grounding, disconnects, and over current protection of particular importance.
Failure to observe these precautions could result in severe bodily injury or loss of life.
This equipment is at line voltage when AC power is connected. Disconnect and lock out all ungrounded conductors of the AC power line. Failure to observe these precautions could result in severe bodily injury or loss of life.
The maximum recommended cable length is 90 m (295.2 ft). If the distance between the motor and the drive requires long motor cables, you may need to add an output reactor or cable terminators to limit
voltage reflections at the motor. Refer to Figure 3.6 for motor power
connections.
Publication 8720MC-IN001D-EN-P — December 2002
Building Your 8720SM
Motor Cables
Connecting Your 8720MC 3-3
When building your own cables for use with the 8720SM motors, follow the guidelines listed below.
• Connect the cable shield to the connector shells on both ends of the cable with a complete 360° connection.
• Use a twisted pair cable whenever possible, twisting differential signals with each other, and single-ended signals with the appropriate ground return.
Note: MP-Series motor cables are factory supplied. Contact your local
Allen-Bradley representative for latest availability.
Shielded Motor Cable
The use of a four-wire type VFD, 600 volt, UL listed cable is strongly
recommended for all motor currents at or below 130 amperes. Figure
3.1 illustrates the type of cable required.

You should always use shielded motor cable. You must connect the shield to the drive chassis (PE) connection and the motor frame. Make the connection at both ends to minimize the external magnetic field.
If you use cable trays or large conduits to distribute the motor leads for multiple drives, use shielded cable to reduce or capture the noise from the motor leads and to minimize cross coupling of noise between the leads of different drives.

For applications above 130 amps, use thick insulation lead wire, such as RHW-2 or equal. Make sure you thread the four wires (U, V, W, and ground) through a single, grounded, metal conduit.
Publication 8720MC-IN001D-EN-P — December 2002
Connecting Your 8720MC 3-5
Conduit
For applications above 130 amperes, metal conduit is required for cable distribution. Follow these guidelines:
• Drives are normally mounted in cabinets, and ground connections are made at a common ground point in the cabinet. If the conduit is connected to the motor junction box and the drive end is connected to the ground panel in the cabinet, you do not need any additional conduit connections.
• Route no more than three sets of motor leads and a ground wire through a single conduit. This minimizes cross talk that could reduce the effectiveness of the noise reduction methods described. If more than three drive/motor connections per conduit are required, use shielded cable. If practical, each conduit should contain only one set of motor leads.
• It is recommended that you use a thick insulation lead wire, such as type RHW-2 or equal.
ATTENTION
!
To avoid a possible shock hazard caused by induced voltages, ground unused wires in the conduit at both ends. For the same reason, if a drive sharing a conduit is being serviced or installed, disable all drives using this conduit.
This eliminates the possible shock hazard from cross coupled drive motor leads.
General Wire Guidelines
You should observe all applicable safety and national and local regulations when selecting the appropriate wire size for your system.
Due to the drive overload capacity of 150% of the continuous current rating for one minute, the conductors for the transformer primary and secondary must be sized (at a minimum) for 125% to 160% of the maximum continuous input current for the motor selected. The motor conductors must also be rated for a minimum of 125% to 160% of the full load motor continuous current. If less than 150% overload is required the torque limit parameters must be set in the drive accordingly. The distance between the drive and motor may affect the size of the conductors used. To protect against interference, use shielded wire in motor and control circuits. A shielded cable is required for all feedback signal wires.

Routing Power and Signal Wiring
Be aware that when you route power and signal wiring on a machine or system, radiated noise from nearby relays, transformers, and other electronic drives, can be induced into motor or encoder feedback, communications, or other sensitive low voltage signals. This can cause system faults and communication problems.
Refer to Chapter 1 for examples of routing high and low voltage
cables in wireways. Refer to System Design for Control of Electrical
Noise (publication GMC-RM001x-EN-P) for more information.

Grounded Distribution
Systems
The AC input drives are designed for use with conventional three-phase supplies that are symmetrical with respect to ground.
Surge suppression devices are included to protect the drive from lightning-induced over voltage between line and ground. For this reason, use a neutral grounded system. The drive works with a grounded phase, but you may want to use an isolation transformer to provide a supply balanced with respect to ground.

Ungrounded Distribution
Systems
All 8720MC AC input drives are equipped with a metal oxide varistor
(MOV). The MOV provides voltage surge protection, phase-to-phase as well as phase-to-ground, which is designed to meet IEEE 587. The
MOV circuit is designed for surge suppression only (transient line protection), not continuous operation.
With ungrounded distribution systems, the phase-to-ground MOV connection could become a continuous current path to ground. MOV line-to-line and line-to-ground voltages should not exceed the input
voltage rating shown in Appendix A. Exceeding these values may
cause physical damage to the MOV.
Publication 8720MC-IN001D-EN-P — December 2002
Grounding Your
8720MC
Connecting Your 8720MC 3-9
We recommend that all equipment and components of a machine or process system have a common earth ground point connected to their chassis. A grounded system provides a ground path for short circuit protection. Grounding your system minimizes the shock hazard to personnel and damage to equipment caused by short circuits, transient overvoltages, and accidental connection of energized conductors to the equipment chassis. For CE grounding requirements,
IMPORTANT
To improve the bond between the 8720 system components and subpanel, construct your subpanel out of zinc plated (paint-free) steel.
When grounding your 8720MC drive follow these guidelines:
• Identify a good source of earth ground such as a ground rod or a clean low resistance connection to a steel building structure.
Connect the PE terminal provided on TB1 to earth ground.
• Define the paths through which the high frequency ground currents flow. Isolate the wires carrying these currents.
• Connect the ground conductor of the motor cable (drive end) directly to the drive ground PE terminal, not to the enclosure ground bus bar.
• Ground the CE filter to the bonded cabinet ground bar.
• The D-frame amplifiers (8720MC-D097, -D120, -D149, and -D180) have a TE terminal. The TE block is used for all control signal shields internal to the drive. It must be connected to the bonded cabinet ground bar by a separate continuous lead.
Publication 8720MC-IN001D-EN-P — December 2002
3-10
Connecting Your 8720MC
Connecting the Drive to the System Ground
Connect the drive to earth ground via the power ground (PE) terminal
provided on the power terminal block (TB1) as shown in Figure 3.4.
You should inspect and test the ground impedance at appropriate and regular intervals.
Note: Even if you have a floating secondary, the building must have a safety (earth) ground.
In any cabinet, you should use a single, low-impedance ground point or ground bus bar. You should:
• Ground all circuits independently and directly to this ground point or bus bar.
• Directly connect the AC supply ground conductor to this ground point or bus bar.
ATTENTION
!
The National Electrical Code contains grounding requirements, conventions, and definitions. Follow all applicable local codes and regulations to safely
ground your system. Refer to Appendix B for the
8720MC interconnect diagrams.

Motor Power Cable Shield Terminations
The motor power cable shield must terminate at the drive and where the cable enters the cabinet to meet CE requirements.
ATTENTION
!
To avoid hazard of electrical shock, ensure shielded power cables are grounded at a minimum of one point for safety.
A portion of the cable jacket must be removed at the drive end to expose the shield braid and leave an appropriate length for each conductor. The shield must be positioned under the clamp as shown in the figure below.
Another portion of the cable jacket is removed where the cable enters the enclosure and a 360° conduit clamp applied (as shown in the figure below).

Feedback and I/O Connectors
Six Weidmueller connectors (3 double row pairs) are used to connect the motor feedback, the auxiliary feedback, the analog I/O, the registration inputs, the digital I/O and the relay outputs.
IMPORTANT
The front and back connectors are identical and consequently care must be taken to label the cables so that they can not be inadvertently switched.
IMPORTANT
Keep the feedback and signal wiring separated from noise generating sources such as the motor cables.
Wherever possible run the control wires in different conduits from the motor leads.
Refer to page 3-25 for available pre-molded cables.
P4, and P5 Connectors
The P4 and P5 connectors on the 8720MC control board have two mating connectors each. One is for the front row and one is for the back row when looking directly at the main control PC board. P4 connections 1-4, back row, are made through the lower mating connector and connections 5-8 are made through the front mating connector. The same is true for P5, but the lower terminations are 1-18
and the upper terminations are 19-36. Refer to Figure 2.4 for the P4
and P5 connectors.
The mating connectors are mechanically keyed and, therefore, it is not possible to put the connectors in backward. It is possible to switch the front and back connectors therefore care must be taken to prevent reversing the upper and lower connectors. You can accomplish this by using connector labels or you can tie wrap the cables to the chassis.

Wiring I/O Connections
To wire your P1, P4, and P5 connectors:
1. Prepare your I/O wires by stripping approximately 12.7 mm (0.5 in.) of insulation from the end.
IMPORTANT
Use caution not to nick, cut, or otherwise damage strands as you remove the insulation.
2. Use a small blade type screw driver and depress the spring clamp next to the pin you will wire and insert the wire, as shown in
Figure 3.10 and Figure 3.11. The P4 and P5 wire terminations are
designed for stripped AWG 22 to AWG 14 wire.
