Protective Stop(input)
Function
Opening this input signal circuit in Automatic Operation allows the external device to continue-stop the robot. (dual line)
The stop category is category 1. (See IEC60204-1 for details of stop category)
Terminal Number
| Signal name | Terminal number |
|---|---|
| Protective Stop input 1 | #4 and #38 on Mini I/O connector |
| Protective Stop input 2 | #5 and #39 on Mini I/O connector |
Usage
This signal is used for a safety door switch and other safety devices.
Input Conditions and Operation
If the protective stop is released in Automatic Operation, the program is suspended and the motor is turned off. Errors are not issued. If the protective stop is released in Automatic Operation, motor power on and the program startup are disabled. This state is used for a safety door switch.
Two Protective Stop input signal circuits must be controlled with two separate contacts each. Two circuits connected in parallel using a single contact or an always-shorted circuit will be interpreted as an external circuit error so that the circuitry will not operate.
Input Timing
In Automatic Operation, this signal will be processed prior to other input signals and all commands.
Considering the order of recovery from the stops, such as the Emergency Stop and Protective Stop, is unnecessary. To recover from the Protective Stop, open the two junctions on the Protective Stopp lines, and then close them.
