* Speed regulation is defined as follows:
The motor speed may change due to voltage variations or amplifier drift and changes in processing
resistance due to temperature variation. The ratio of speed changes to the rated speed represent speed
regulation due to voltage and temperature variations.

Dynamic Brake (DB) Operated at main power OFF, servo alarm, servo OFF or overtravel
Regenerative Processing External regenerative resistor Built-in
Overtravel Prevention (OT) Dynamic brake stop at P-OT or N-OT input, deceleration to a stop, or free run to a
stop
Electronic Gear 0.001 ≤ B/A ≤ 1000
Protection Overcurrent, overvoltage, insufficient voltage, overload, regeneration error, main
circuit sensor error, heat sink overheat, power line phase loss, position error pulse
overflow, overspeed, encoder error, overrun detection, CPU error, parameter error,
etc.
LED Display CHARGE, power, COM 7-segment LEDs (status display)
Others Reverse connection, zero position search, automatic motor discrimination function
