Protection Features

The PG Motion System supports protection features that work via Controller’s safety functions and the software, and standard protective features.

The following table describes how each system protection feature is supported for PG robots.

The protection features that work via Controller’s safety functions and the software

Protection Features Supported Function on the PG Board
Emergency Stop

Stop generating pulse. This emergency stop function is supported only by the software. Emergency stop must also be supported in hardware also. Make sure to install an additional circuit for the purpose of stopping the motor physically in case of emergency.

In particular, the way of turning off the main power of the motor driver is described below.

RC700/RC90: Typical Application of Emergency Stop Circuit

For more details, refer to the Robot Controller manual.

RC700-E/RC800-A: Typical Application of Safety Output

Safeguard The safeguard input is notified through the software then decelerates and stops.
Enable Switch The enable switch input is notified through the software. If the switch is gripped, the pulse input will turn ON, and the switch is gripped harder, the pulse input will turn OFF.

The standard protective features

Protection Features Supported Function on the PG Board
High/Low Power Mode

The function of this mode is same as for a standard robot.

The acceleration/deceleration is set as follows for the Low Power and High Power state respectively:

  • Low Power:

    Acceleration and deceleration will be limited. The acceleration and deceleration value of default are fixed as follows: Acceleration : 10 Deceleration : 5

  • High Power:

    The maximum speed, acceleration and deceleration will be operable at the set-up maximum value in the software.

Mode Switch If the mode is changed, the pulse will stop.
