Sequence input signal
Emergency stop, 3 external latch signals, forward/reverse torque limit, forward/reverse run prohibit, origin prox-
imity, 3 general-purpose inputs
Sequence output signal
It is possible to output three types of signals: positioning completed, speed coincidence, rotation speed detection,
servo ready, current limit, speed limit, brake release and warning signal

Automatic load inertia detection
Horizontal and vertical axis mode. One parameter rigidity setting.
Dynamic brake (DB)
Operates when main power OFF, servo alarm, overtravel or servo OFF
Regenerative processing
Built-in regeneration resistor in models from 750 W to 1.5 kW. External regeneration resistor optionally.
Overtravel (OT) prevention function
Dynamic brake, disables torque or emergency stop torque during POT and NOT operation
Emergency stop (STOP)
Emergency stop input
Encoder divider function
Optional division pulses possible
Electronic gearing
0,01<Numerator/Denominator<100
Internal speed setting function
8 internal speeds
Protective functions
Overvoltage, undervoltage, overcurrent, overload, regeneration overload, servo drive overheat
Analog monitor Ouput
The actual servomotor speed, command speed, torque and number of accumulated pulses can be measured u-
sing an oscilloscope or other device.
Panel operator
Display functions
A 2-digit 7-segment LED display shows the servo drive status, alarm codes, parameters, etc.
MECHATROLINK-II communications status LED indicator (COM)
