          Origin return

          Origin return method

          There are two types of origin returning operations : high-speed returning (which does not require the sensor in front of the origin) and origin returning that shares the CCW limit switch and the origin sensor. Origin detection can be set to the AND condition of the origin sensor and the Z-phase. There is a function for automatically returning to the origin when the power is turned on. There is a function for automatic travel to the home position when the origin returning operation completes.

          Teaching

          Current coordinate teaching using JOG travel, direct teaching using the current counter value, external teaching from a PLC

          High-speed counter

          Signed 24-bit (counts from -8,388,608 to +8,388,607) × 2, each of the 2 comparators has a fractional coordinate transformation function, speed changing by way of comparator matching, deceleration stop, fixed dimension feeding deceleration stop

          Data backup

          EEPROM rewritable 100,000 times. Electric double-layer capacitors are used to hold the current coordinate and current value of the high-speed counter for 2 months (at 25°C). Parameters that are changed by the PLC are written to the EEPROM the next time that the power is turned on.
