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. | ||

Sensor positioning | Positioning to an arbitrary point through the use of a stop sensor | |||
Palletizing | Repeated addition of relative amount, return function | |||
Error indication | Output of error details to the KZ-HP1 or CPU unit | |||
Self-diagnosis | Diagnoses can be performed according to hardware errors, various parameter errors, error numbers, and messages. | |||
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. | |||
Teaching | Current coordinate teaching using JOG travel, direct teaching using the current counter value, external teaching from a PLC | |||
Power flicker detection | Stops operation when a power flicker error is detected | |||
Parameter settings | This is also possible by way of setting the data memory and controlling the relays of the KZ-HP1 teaching unit or of the dedicated parameter settings monitor software. | |||
Internal current consumption | Main unit side : 185 mA (280 mA when the KZ-HP1 is connected), I/O side : 150 mA | |||
