Velocity - Torque Characteristic Curve (T-N Curve)
A graph representing the relationship between the velocity and torque when a DD motor is
driven. The horizontal axis shows the velocity (rpm) and the vertical axis shows torque (N-m).
Velocity Override
A velocity scale in which the feed velocity set up by a parameter is 100%, which can be set in
a range from 0% and 200%.
Velocity Profile
A time differential waveform of the position command. The ideal operation path generated in
the drive.
W
Watchdog Timer
A mechanism for preparing for a situation where programs cannot be executed normally due
to uncontrollable running and other reasons. This timer functions just like a watchdog. A
minimum communication can be performed even if a watchdog timer error occurs in this
drive.

Y
Z
ZERO
Motor origin signal. Software and hardware Z-pulses are available depending on the
generation method. There are several of them in one rotation or one stroke.
Number of rotations (rpm)
Torque (N-m)
Maximum output torque
Rated torque
Maximum number of rotations
