Chapter 1: Safety Information

Warning:

Caution:

Gold Bell Installation Guide

In order to achieve the optimum, safe operation of the Gold Bell servo drive, it is imperative
that you implement the safety procedures included in this installation guide. This information is
provided to protect you and to keep your work area safe when operating the Gold Bell and
accompanying equipment.

Please read this chapter carefully before you begin the installation process.

Before you start, ensure that all system components are connected to earth ground. Electrical
safety is provided through a low-resistance earth connection.

Only qualified personnel may install, adjust, maintain and repair the servo drive. A qualified
person has the knowledge and authorization to perform tasks such as transporting, assembling,
installing, commissioning and operating motors.

The Gold Bell servo drive contains electrostatic-sensitive components that can be damaged if
handled incorrectly. To prevent any electrostatic damage, avoid contact with highly insulating
materials, such as plastic film and synthetic fabrics. Place the product on a conductive surface
and ground yourself in order to discharge any possible static electricity build-up.

8

To avoid any potential hazards that may cause severe personal injury or damage to the product
during operation, keep all covers and cabinet doors shut.

The following safety symbols are used in this manual:

This information is needed to avoid a safety hazard, which might cause bodily
injury.

This information is necessary for preventing damage to the product or to
other equipment.

MAN-G-BELIG (Ve r. 1.004)

Gold Bell Installation Guide Safety Information

1.1. Warnings

• To avoid electric arcing and hazards to personnel and electrical contacts, never

connect/disconnect the servo drive while the power source is on.

• Power cables can carry a high voltage, even when the motor is not in motion. Disconnect

the Gold Bell from all voltage sources before it is opened for servicing.

• The Gold Bell servo drive contains grounding conduits for electric current protection. Any

disruption to these conduits may cause the instrument to become hot (live) and dangerous.

• After shutting off the power and removing the power source from your equipment, wait at

least 1 minute before touching or disconnecting parts of the equipment that are normally
loaded with electrical charges (such as capacitors or contacts). Measuring the electrical
contact points with a meter, before touching the equipment, is recommended.

1.2. Cautions

• The Gold Bell servo drive contains hot surfaces and electrically-charged components during

operation.

9

• The maximum DC power supply connected to the instrument must comply with the

parameters outlined in this guide.

• When connecting the Gold Bell to an approved isolated 12–95 VDC auxiliary power supply,

connect it through a line that is separated from hazardous live voltages using reinforced or
double insulation in accordance with approved safety standards.

• Before switching on the Gold Bell, verify that all safety precautions have been observed

and that the installation procedures in this manual have been followed.

• Do not clean any of the Gold Bell drive's soldering with solvent cleaning fluids of pH greater

than 7 (8 to 14). The solvent corrodes the plastic cover causing cracks and eventual damage
to the drive's PCBs.

Elmo recommends using the cleaning fluid Vigon-EFM which is pH Neutral (7).

2.2. Product Features

Note: The features described in this chapter relate to the range of Gold Bell models.

Depending on the model you have purchased, not all features are available.

To see the features for your model, look at the product label on the Gold Bell and use the
product catalog number schematic that appears at the beginning of this manual and on
page 24 to determine which specific features are available to you.

2.2.1. High Power Density

) package (55 x 59 x 15 mm or 2.17” x 2.32” x 0.6”)

www.elmomc.com

MAN-G-BELIG (Ve r. 1.004)

Gold Bell Installation Guide Product Description

2.2.2. Supply Input

• Single DC Power Supply: Power to the Gold Bell is provided by a single 12 V to 95 V isolated

DC power source (not included with the Gold Bell). A “smart” control-supply algorithm
enables the Gold Bell to operate with only one power supply with no need for an auxiliary
power supply for the logic.

• Optional Backup Supply: If backup functionality is required in case of power loss, e.g., to

keep the original position, an external 12 V to 95 V isolated supply should be connected.
This is more flexible than the requirement for 24 VDC supply.
If backup is not needed, a single power supply is used for both the power and logic circuits.

There are multiple voltage ratings of the Gold Bell (12 V to 95 V), so you must use the correct
power supply according to the maximum operating voltage of the Gold Bell. See Section
Chapter 3: Technical Information.

4.4. Mounting the Gold Bell

The Gold Bell was designed for mounting on a printed circuit board (PCB) via 1.27 mm pitch

0.41 mm square pins and 2 mm pitch 0.51 mm square pins. When integrating the Gold Bell into
a device, be sure to leave about 1 cm (0.4") outward from the heat sink to enable free air
convection around the drive. We recommend that the Gold Bell be soldered directly to the
board. Alternatively, though this is not recommended, the Gold Bell can be attached to socket
connectors mounted on the PCB. If the PCB is enclosed in a metal chassis, we recommend that
the Gold Bell be screw-mounted to it as well to help with heat dissipation. The Gold Bell has
screw-mount holes on each corner of the heat sink for this purpose – see below.

33

All measurements are in mm.

Figure 2: Gold Bell Dimensions

www.elmomc.com

MAN-G-BELIG (Ve r. 1.004)

Gold Bell Installation Guide Installation

4.5. Integrating the Gold Bell on a PCB

The Gold Bell is designed to be mounted on a PCB, either by soldering its pins directly to the
PCB or by using suitable socket connectors. In both cases the following rules apply:

4.5.1. Traces

1. The size of the traces on the PCB (thickness and width) is determined by the current

carrying capacity required by the application.

• The rated continuous current limit (Ic) of the Gold Bell is the current used for sizing

the motor traces (M1, M2, M3, M4 and PE) and power traces (VP+, PR and PE).

• For control, feedbacks and Input/Output conductors, the actual current is very small

but a greater thickness and width of the conductors will contribute to better
performance and less interference.

2. The traces should be as short as possible to minimize EMI and also to minimize the heat

generated by the conductors.

3. The spacing between the high voltage conductors (VP+, PR, M1, M2, M3, M4, VL) must be

at least:

34

• Surface layer: 1.5 mm

• Internal layer: 0.10 mm

Complying with the rules above will help satisfy UL safety standards, MIL-STD-275 and the IPC­D-275 standard for non-coated conductors, operating at voltages lower than 200 VDC.

4.5.2. Grounds and Returns

The returns in each functional block are listed below:

Functional Block Return Pin

Power PR (Power Return)

Internal Switch Mode P. S. PR (Power Return)

Analog input return ANLRET (J2/20)

Common return COMRET (J2/25,31,32,43,46; J1/23)

STO safety signal return STO_RET (J1/10)

Input Return IN_RET (J1/3)

Table 8: Grounds and Returns

www.elmomc.com

MAN-G-BELIG (Ve r. 1.004)

Gold Bell Installation Guide Installation

The returns above are all shorted within the Gold Bell in a topology that results in optimum
performance.

Caution:
Follow these instructions to ensure safe and proper implementation. Failure to
meet any of the below-mentioned requirements can result in drive, controller or
host failure.

1. When wiring the traces of the above functions, on the Integration Board, the Returns of

each function must be wired separately to its designated terminal on the Gold Bell. DO
NOT USE A COMMON GROUND PLANE. Shorting the commons on the Integration Board
may cause performance degradation (ground loops, etc.).

2. Inputs: The six digital inputs are optically isolated from the other parts of the Gold Bell. All

six inputs share one return line, INRET. To retain isolation, the Input Return pin and all
other conductors on the input circuit must be laid out separately.

3. STO: The two digital STO inputs are optically isolated from the other parts of the Gold Bell.

All six inputs share one return line, INRET. To retain isolation, the Input Return pin and all
other conductors on the input circuit must be laid out separately

35

4. Outputs: The two digital outputs are optically isolated from the other parts of the Gold

Bell. To retain isolation, all the output circuit conductors must be laid out separately.

5. Return Traces: The return traces should be as large as possible, but without shorting each

other, and with minimal cross-overs.

6. Main Power Supply and Motor Traces: The power traces must be kept as far away as

possible from the feedback, control and communication traces.

7. PE Terminal: The PE (Protective Earth) terminal is connected directly to the Gold Bell’s

heat-sink which serves as an EMI common plane. The PE terminal should be connected to
the system's Protective Earth. Any other metallic parts (such as the chassis) of the assembly
should be connected to the Protective Earth as well.

8. Under normal operating conditions, the PE trace carries no current. The only time these

traces carry current is under abnormal conditions (such as when the device has become a
potential shock or fire hazard while conducting external EMI interferences directly to
ground). When connected properly the PE trace prevents these hazards from affecting the
drive.

4.7.4. Single Supply

A single isolated DC power supply can provide power for both the main power and the Auxiliary
(Drive Logic) Supply. The drawing below shows how a single supply is connected.

41

4.7.5. Separate Auxiliary (Backup) Supply

Power to the Auxiliary Supply can be provided by a separate Auxiliary Supply.

Gold Bell Installation Guide Installation

4.7.6. Shared Supply

A Main DC Power Supply can be designed to supply power to the drive’s logic as well as to the
Main Power (see Figure 8 and the upper portion of Figure 10). If backup functionality is
required for continuous operation of the drive’s logic in the event of a main power-out, a
backup supply can be connected by implementing “diode coupling” (see the Aux. Backup
Supply in Figure 10).

42

Figure 10: Shared Supply Connection Diagram

www.elmomc.com

MAN-G-BELIG (Ve r. 1.004)

Gold Bell Installation Guide Installation

4.8. STO (Safe Torque Off) Inputs

Activation of Safe Torque Off causes the drive to stop providing power that can cause rotation
(or motion in the case of a linear motor) to the motor.

This function may be used to prevent unexpected motor rotation (of brushless DC motors)
without disconnecting the drive from the power supply.

The motor is active only as long as 5 V is provided to both STO1 and STO2. Whenever any input
voltage is no longer present, power is not provided to the motor and the motor shaft continues
to rotate to an uncontrolled stop.

The STO inputs are latched which means that the motor can be re-enabled by a software
command only.

In circumstances where external influences (for example, falling of suspended loads) are
present, additional measures such as mechanical brakes are necessary to prevent any hazard.

This function corresponds to an uncontrolled stop in accordance with Stop Category 0 of IEC
60204-1.

43

Note: This function does not protect against electrical shock, and additional measures to

turn the power off are necessary.

The following table defines the behavior of the motor as a function of the state of the STO
inputs:

Signal – STO1 Signal – STO2 Function

Not Active Not Active Motor is disabled

4.9. Feedback

Figure 14: Feedback Ports on J2

The Gold Bell has two configurable motion sensor input ports, namely, Port A and Port B,
together with the emulated buffered output Port C. Motion sensors from the motor are
controlled from other sources and can be connected to any of the available inputs on Port A or
Port B.

46

The software configuration designates a role to each input, e.g., the incremental encoder on
port B is the controlled motor position feedback, the Hall sensors on port A are commutation
feedback, and the incremental encoder on port A is follower input.

For more information, about sensors and their use refer to the Gold Line Software Manual.

• Port A/B daisy chain (1:1) for incremental encoder

• Encoder emulation: Emulate any input sensor, digital or analog, or use to emulate an

internal variable such as virtual profiler.

• PWM output: any pair of outputs that is used as an encoder channel (e.g., channel A+ and

channel A-) can be configured by software to become PWM output.

• Pulse & Direction output: The output pins that are assigned as channel A and channel B

when used as encoder out can be configured by software to become pulse and direction
outputs, respectively.

This port is used when:

• The Gold Bell is used as a current amplifier to provide position data to the position

controller.

54

• The Gold Bell is used in velocity mode to provide position data to the position controller.

• The Gold Bell is used as a master in follower or ECAM mode.

communicate using the following options:

Standard EtherCAT

G-BELXXX/YYYSX G-BELXXX/YYYEX

CAN EtherCAT

USB 2.0 USB 2.0

Ethernet RS-232 (TTL Logic Level)

RS-232 (TTL Logic Level)

Table 20: Gold Bell Communication Options

For ease of setup and diagnostics of CAN communication, RS-232 and CAN can be used
simultaneously.

61

Note: When the EtherCAT is connected, and FoE in operation, the USB cable connection

must be disconnected.

4.11.1. RS-232 Communication (J2)

RS-232 communication requires a cable connected from the Gold Bell to a serial interface on
the PC. The interface is selected and set up in the Elmo Application Studio (EAS) software.

RS-232 communication of the Gold Bell is at the TTL logic level. It requires an RS-232 Line
Driver/Receiver in order to translate the TTL logic level to the standard RS-232 voltage level.

Notes for connecting the RS-232 communication cable:

• Connect the shield to the ground of the host (PC). Usually, this connection is soldered

internally inside the connector at the PC end. You can use the drain wire to facilitate
connection.

• The RS-232 communication port is non-isolated.

• Ensure that the shield of the cable is connected to the shield of the connector used for

RS-232 communications. The drain wire can be used to facilitate the connection.

isolation transformer. The most common solution is to use RJ-45 connectors that include
transformer isolation.

This section describes how to connect the Gold Bell’s EtherCAT interface using the above
mentioned connectors.

For other available options, please see Section 4.11.6.

Notes for EtherCAT Communication:

• The EtherCAT IN port can be configured as an Ethernet port for TCP/IP – see the EtherCAT

When connecting several EtherCAT devices in a network, the EtherCAT master must always be
the first device in the network. The output of each device is connected to the input of the next
device. The output of the last device may remain disconnected. If redundancy is required, the
output of the last device should be connected to the input of the EtherCAT master.

4.11.6. EtherCAT/Ethernet Line Interface

Ethernet transceivers require either isolation transformers or capacitor coupling for proper
functioning. The Gold Bell unit does not include such isolation, therefore you must take this
into consideration when designing the integration board.

In Sections 4.11.4 and 4.11.5, a schematic connection with a standard RJ-45 connector that
includes transformer isolation is described.

Other recommended connection options are:

• Gold Bell to an RJ-45 connector without an integrated magnetic isolation (e.g., M12

connectors). An isolation transformer is required.

• Connecting two EtherCAT ports on the same board can be done using capacitive coupling

or transformer coupling.

For more detailed explanations, including layout recommendations and component selection
guidelines contact Elmo’s technical support.

4.12. Powering Up

70

After the Gold Bell is connected to its device, it is ready to be powered up.

Caution:
Before applying power, ensure that the DC supply is within the specified range
and that the proper plus-minus connections are in order.

4.13. Initializing the System

After the Gold Bell has been connected and mounted, the system must be set up and
initialized. This is accomplished using the Composer, Elmo’s Windows-based software
application. Install the application and then perform setup and initialization according to the
directions in the Composer Software Manual.

4.14. Heat Dissipation

The best way to dissipate heat from the Gold Bell is to mount it so that its heatsink faces up.
For best results leave approximately 10 mm of space between the Gold Bell's heatsink and any
other assembly.

4.14.1. Thermal Data

• Heat dissipation capability (θ): Approximately 10 °C/W.

• Thermal time constant: Approximately 240 seconds (thermal time constant means that the

Bell will reach two-thirds of its final temperature after 4 minutes.)

• Shut-off temperature: 86 °C – 88 °C (measured on the heatsink).

4.14.3. How to Use the Charts

The charts above are based upon theoretical worst-case conditions. Actual test results show
30% – 50% better power dissipation.

To determine if your application needs a heatsink:

1. Allow the maximum heatsink temperature to be 80 °C or less.

2. Determine the ambient operating temperature of the Gold Bell.

3. Calculate the allowable temperature increase as follows:

 For an ambient temperature of 40 °C, ΔT= 80 °C – 40 °C = 40 °C.

4. Use the chart to find the actual dissipation power of the drive. Follow the voltage curve to

the desired output current and then find the dissipated power.

5. If the dissipated power is below 4 W, the Gold Bell will not need additional cooling.

Note: The chart above shows that no heatsink is needed when the heatsink temperature is

80°C, the ambient temperature is 40 °C and the heat dissipated is 4 W.
