*4
Forward is clockwise viewed from the non-load side of the servomotor, (counterclockwise viewed
from the load and shaft end).
*1
The built-in open collector power supply is not electrically isolated from the control circuit in the servo amplifier.

mode), forward rotation prohibited (P-OT), reverse rotation prohibited (N-OT),
alarm reset, forward rotation current limit and reverse rotation current limit (or
contact input speed control)

Dynamic Brake (DB) (Supplied as an option
unit)
Activated at main power OFF, servo alarm, servo OFF or overtravel.
Regenerative Processing
A regenerative resistor must be mounted externally.
Overtravel (OT) Prevention
Motor is stopped by dynamic brake (requires optional dynamic brake unit),
decelerates to a stop, or coasts to a stop when P-OT or N-OT is activated.
Protection
Overcurrent, overload, regenerative error, main circuit voltage error, heat sink
overheat, power open phase, overflow, overspeed, encoder error, encoder
disconnected, overrun, CPU error, parameter error.
LED Display
POWER, ALARM, CHARGE, five 7-segment LEDs, (built-in digital operator
functions)

Interface
Digital operator (mount type or hand-held).
RS422A port such as a personal computer (RS-232C port can be used if some
conditions are met).
1 : N Communication
N can be up to 14 when RS422A port is used.
Axis Address Setting
Set with parameter.
Functions
Status display, user constant setting, monitor display, alarm traceback
display, jogging, autotuning, etc.
Others
Zero-clamp, reverse rotation connection, jog operation, home position search,
automatic servomotor ID.
