Noise immunity	1,500 Vp-p, pulse width : 1 µs, 50 ns (by way of a noise simulator)
Withstand voltage	1,500 VAC for 1 minute between the power supply terminal and the I/O terminals and between all the external terminals and the case
Insulation resistance	50 MΩ or more (tested with a 500 VDC megger, between the PLC power supply terminal and the I/O terminals and between all the external terminals and the case)
Intermittent vibration	Frequency: 10 to 57 Hz, Amplitude : 0.075 mm3Frequency: 57 to 150 Hz, Acceleration : 9.8 m/s23
Continuous vibration	Frequency: 10 to 57 Hz, Amplitude : 0.035 mm3Frequency: 57 to 150 Hz, Acceleration : 4.9 m/s23
Number of control axes (Positioning control)	2-axis simultaneous (linear interpolation, circular interpolation), 2-axis independent
Cumulative address (Positioning control)	-2,147,483,648 to +2,147,483,647 pulses (2 to the power of 32)
Positioning mode (Positioning control)	Absolute coordinate, relative coordinate, speed control to positioning, positioning to speed control, speed control (only during independent operation)
Position setting range (Positioning control)	±99,999,999
Startup time (Positioning control)	Independent operation : 1.1 ms, linear interpolation : 1.8 ms, circular interpolation : 2.1 ms
M-code (Positioning control)	Number 1 to 255, WITH/AFTER mode
Origin return method (Origin return)	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.
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
Applicable PLCs	KV-700
Maximum number of series connectable units	48 maximum (For 16 units or more, extension units are necessary.)
Number of memory points	400 (for each axis)
Occupied device	For each unit : input : 5 channels, output : 5 channels, arbitrary data registers (data memory) : 280 words
Position setting units	mm, angle, number of pulses, fractional coordinate transformation unit, decimal point position : digit 0 to 7
Speed setting range	1 to 500,000 p/s : automatic trapezoid, cosine, second-order curve, third-order curve, parabola acceleration and deceleration (the starting speed is 0 to 500,000 p/s); 1 to 99,999,999 when the setting unit is mm/s or deg/s
Acceleration/deceleration setting range	1 to 65000 mm/s/ms, deg/s/ms, p/s/ms
Acceleration/deceleration control units	Acceleration : 1 ms, deceleration : 2 ms
Continuous operation	Standby after deceleration, start immediately after deceleration, consecutive acceleration and deceleration without deceleration
Pulse output format	Line driver output, 1/2 pulse method
External interface	Input : 24 VDC, photocoupler input; output : open-collector output (30 VDC, 300 mA), no overcurrent protection circuit
5 V power source	5 V ±10%, 100 mA maximum (when 24 VDC is applied to input connectors 13 and 14)
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
Weight	Approx 200g
