GE CBL-T7-MP-20 Motion Control Cables

S-Series Servo Motor Power and Brake Wiring and Grounding 

Motor power and brake cables as shown in Table 3-13 are available from GE Fanuc for the S2K 

Series Servo Controllers. Cables for S-Series motors with brakes include two 18 AWG leads for 

connection of a 24Vdc brake power supply (see section 2.1.9, Servo Motor Specifications, for brake 

power requirements) and brake control logic. The brakes are of a fail-safe design, engaged by internal 

springs and disengaged by the application of 24 Vdc power. 

The motor cable must have a motor ground wire that connects one of the frame ground terminals on 

the controller to the frame ground pin on the motor connector. Tables to 3-13 show the proper wire 

size and Figure 3-25 shows the motor connector pin-out for each S-Series motor model. For noise 

sensitive applications, a shielded motor power cable may be necessary. 

Note 

A shielded motor power cable is required in CE marked systems. When used, the 

power cable shield should connect to the frame ground stud on the bottom of the 

controller and to the connector at the motor end. GE Fanuc’s standard motor power 

cables do not include a shield. 

On the 30–750 Watt S-Series motors, the power connectors shown in the following figure are wired 

to the motors with short leads and include a separate connector (and require a separate brake cable) 

when the optional holding brake is included. On the 1.0–5.0 kW motors, the MS-style connectors 

shown are mounted directly on the motor’s frame and the brake connections are included in the same 

connector and cable.

FAULT CONDITIONS — In the event of a shortedload, shorted winding, or stalled motor, the load current will attempt to increase.

As described above, the drive current to the output stage is diverted (limiting the load current to about1 A), causing the output stage to go linear. As the junction

temperature of the output stage increases, the thermal limit circuit will become operational, further decreasing the drivecurrent.

The load current (junction temperature) is then a function of ambient temperature, state of remaining drivers,supply voltage, and load resistance.

If the fault condition is corrected, the output driver will return to its normal saturated condition. 

Short circuit protection is provided for each output for supply voltages up to 25 V.

Any program can start and stop any other program, and all programs can utilize common motion blocks. 

Engineering time is reduced and integration is simplified due to configuration and programming wizards for the controller software.
