Chapter 6: Wiring

MAN-G-DCBELIG-EC (Ver. 1.200)
Once the product is mounted, you are ready to wire the device. Proper wiring, grounding and shielding are essential for ensuring safe, immune and optimal servo performance of the drive.
The following table legend describes the wiring symbols detailed in all installation guides.
Wiring Symbol Description
Earth connection (PE)
Protective Earth Connection
Common at the Controller
Shielded cable with drain wire.
The drain wire is a non-insulated wire that is in direct contact with the braid (shielding).
19
Shielded cable with drain wire significantly simplifies the wiring and earthing.
Shielded cable braid only, without drain wire.
Twisted-pair wires
Encoder Earthing.
The cable`s shield is connected to the chassis (PE) in the connector.
Earthing the Encoder and connecting the Earth (PE) to the drive COMRET is mandatory to insure reliable operation, high noise immunity and rejection of voltage common mode interferences.

MAN-G-DCBELIG-EC (Ver. 1.200)

6.1. Basic Recommendations

6.1.1. General

1. Use shielded cables. For best results, the cable should have an aluminum foil shield covered
by copper braid, and should contain a drain wire. Use 24, 26 or 28 AWG twisted-pair shielded with drain wire cables.
2. Keep the cable as short as possible.
Do not mount the power cables of the motor and power bus in the proximity of the control and feedback cables.
3. Ensure that in normal operating conditions, the “earth connection” wires and shield of the
control cables carry no current. The only time these conductors carry current is under abnormal conditions, when electrical equipment has become a potential shock or fire hazard while conducting external EMI interferences directly to ground, in order to prevent them from affecting the drive. Failing to meet this requirement might result in drive/controller/host failure.
4. After completing the wiring, carefully inspect all wires to ensure tightness, good solder of
joints and general safety.

Figure 4: Feedback and Molex Control Cable Assemblies
Note: Please pay attention to the location of PIN 1 in the above connector diagram.
It should be noted that in all Elmo manuals the pinouts are shown differently to Molex’s technical sheets. Molex shows pin 1 at the bottom-left when looking at the face of the cable-side connector, tab down (Figure 5).
Figure 5: Molex vs Elmo Technical Diagram Examples Showing Pinout Numbers
However, Elmo specifies pin 1 as the bottom-left of drive-side connector. The result is that Elmo’s pin designations are mirrored relative to the pinouts as labeled by Molex.
Where there is only one COMRET pin (Common Return) in the connector, which MUST be connected to the DRAIN WIRE and also to COMRET signal of the cable, it is necessary to connect the drain wire and COMRET signal to the same pin.

6.1.2. Feedback Cable Port A and Port B Connector

1. On the motor side connections, ground the shield to the motor chassis.
2. At least One COMRET (Common Return) must be connected to the PE.
Implement the following steps to connect the COMRET to the PE:
a. At the drive, connect the feedback drain wire to one of the COMRET terminals in the
Molex feedback connector (Figure 5.
b. At the motor, connect the feedback cable drain wire to the GND motor chassis
terminal of the feedback connector (Figure 6).

6.3. Main and Auxiliary Power

The Gold DC Bell receives power from main and auxiliary supplies and delivers power to the motor.

6.3.1. Description

This section describes the Main and Auxiliary Power for power ratings 200V and 100V, and provides details for the optional Backup (Auxiliary) Supply.
• The Gold DC Bell Power rating is 12 to 195 VDC
• There are Two power ratings for Gold DC Bell; 100V and 200V:
For power rating 200V
Two power isolated DC power sources are required, main power 12 - 195V and Auxiliary Power 12-95V for the logic.
For power rating of 100V
Single DC Power Supply - Power to the Gold DC Bell is provided by a 12–95 VDC single isolated DC power source (not included with the Gold DC Bell). A “smart” control-supply algorithm enables the Gold DC Bell to operate with only one power supply with no need for an auxiliary power supply for the logic.
Optional Backup (Auxiliary) Supply
If backup functionality is required in case of power loss, e.g., to keep the original position, a 12–95 VDC external isolated supply should be connected (via the Gold DC Bell’s VL+ terminal). 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 two voltage ratings of the Gold DC Bell, therefore the correct power supply must be used, according to the maximum operating voltage of the Gold DC Bell. Refer to section
4.2 Technical Data.
