0 to 4 Mpps (200 Kpps max. at open collector)
Clears error pulse by external signal
A-phase, B.phase, C-phase: line driver output.
Servo ON, P control (or control mode switching, forward/reverse motor rotation by internal speed setting, zero
clamp, command pulse inhibit), forward/reverse run prohibit, forward/reverse current limit (or internal speed
switching), alarm reset.
Servo alarm, alarm codes (3-bit output): CN1 output terminal is fixed
It is possible to output three types of signal form incl.: positioning complete, speed coincidence detection, servo-
motor rotation detection, servo ready, current limit detection, speed limit detection, brake release, warning, NEAR.
Personal computer
Compliant with USB1.1 standard (12 Mbps)
Status display, parameter settings, adjustment functions, utility functions, alarm traceback display, JOG run/au-
totuning operations and graphing functions for speed/torque command signal, etc
Automatic motor parameter setting. One parameter rigidity setting.
Operates during main power OFF, servo alarm, servo OFF or overtravel
Internal resistor included in models from 500 W to 5 kW. Regenerative resistor externally mounted (option).
DB stop, deceleration stop or coast to stop during P-OT, N-OT operation
Optional division pulses possible
0,01< Numerator/Denominator<100
3 speeds may be set internally
Overcurrent, overvoltage, low voltage, overload, regenerative error
Integrates analog monitor connector for supervision of the speed and torque reference signals, etc.
