Note 1. 150mA is the value applicable when all I/O signals are used. The current capacity can be decreased by reducing the number of
I/O points.
2. When closely mounting the servo amplifier of 3.5kW or less, operate them at the ambient temperatures of 0 to 45
or smaller effective load ratio.

Select the required ones from among 31 preset point tables and perform
operation in accordance with the set values.
Use the external input signal or communication function to choose the point
tables.
Servo motor speed can be varied continuously until the preset moving
distance is reached. (Max. set speeds: 255 speeds)
By merely choosing one point table and starting operation, positioning can
be executed continuously in accordance with several point tables.
Dog type, count type, data setting type, stopper type, home position

High-resolution encoder of 262144 pulses/rev is used as a servo motor
encoder.
By merely setting the home position once, home position return need not
be done at each power on.
You can switch between gains during rotation and gains during stop or use
an external signal to change gains during operation.
This function suppresses vibration at the arm end or residual vibration.
Servo amplifier detects mechanical resonance and sets filter characteristics
automatically to suppress mechanical vibration.
Suppresses high-frequency resonance which occurs as servo system
response is increased.
Analyzes the frequency characteristic of the mechanical system by simply
connecting a servo configuration software-installed personal computer and
servo amplifier.
MR Configurator MRZJW3-SETUP221E is necessary for this function.
Can simulate machine motions on a personal computer screen on the basis
of the machine analyzer results.
MR Configurator MRZJW3-SETUP221E is necessary for this function.
Personal computer changes gains automatically and searches for
overshoot-free gains in a short time.
MR Configurator MRZJW3-SETUP221E is necessary for this function.
