Safety Features The NextMove card incorporates many safety features:
• A Limit Error signal is generated at the end of travel limits.
• The maximum permissible following error, before cutting power to the
motors, can be pre-set.
• A Control Stop input is used to bring all axes to a controlled stop.
• An External Error input is used to bring all axes to a quick stop, ie E Stop.
• The system watchdog (Jumper L) resets the processor in the event of a
major operating firmware malfunction.
Change-over Relay A change-over relay which is energized under software control is included on
the NextMove card to provide a volt free contact, it is used to provide the
software controlled E Stop. The relay is controlled by a latch which is cleared
during reset of the card. Reset occurs on power down, watchdog error or under
control of the PC. Reset is indicated by all three LEDs being illuminated at the
same time.
