2-3 Grounding
The SRCP30 controller must be grounded to prevent danger to personnel from electrical shocks in
case of electrical leakage and prevent equipment malfunctions due to electrical noise.
We strongly recommend that Class D (grounding resistance of 100 ohms or less) or higher grounding
be provided. To ground the terminal, use the protective wiring terminal.
* Class D grounding is the same as Class 3 grounding previously used.

Connecting the SRCP30 to the Control Unit

The SRCP30 controller can be operated either through the TPB programming box or through a PC
(personal computer) equipped with an RS-232C terminal.
When using the TPB, plug the TPB cable connector into the PB connector of the SRCP30 controller.
(Refer to "4-1-1 Connecting the TPB to the SRCP30 controller".)
When using a PC, plug the RS-232C interface cable connector (25 pins) into the PB connector of the
SRCP30 controller. (Refer to "11-2 Communication Cable Specifications".)
To prevent equipment malfunction due to noise, we strongly recommend that Class D (grounding
resistance of 100 ohms or less) or higher grounding be provided.

Connecting to the Robot

First make sure that the power to the SRCP30 controller is turned off, and then connect the robot
cable to the robot I/O connector and motor connector on the front panel of the SRCP30 controller.
Fully insert the robot cable until it clicks in position.
* When the robot cable is disconnected from the controller, an alarm (15: FEEDBACK ERROR
2) is issued.
