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 at 75%
or smaller effective load ratio.
1.3 Function list
The following table lists the functions of this servo. For details of the functions, refer to the reference field.
Function Description Reference
Positioning by automatic operation
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.
Section 5.4
Varied speed operation
Servo motor speed can be varied continuously until the preset moving
distance is reached. (Max. set speeds: 255 speeds)
Section 5.4.2 (4)(b)
Automatic continuous positioning
operation By merely choosing one point table and starting operation, positioning can
be executed continuously in accordance with several point tables.
Section 5.4.2 (4)
Home position return
Dog type, count type, data setting type, stopper type, home position
ignorance, dog type rear end reference, count type front end reference, dog
cradle type
Section 5.6
High-resolution encoder
High-resolution encoder of 262144 pulses/rev is used as a servo motor
encoder.
Absolute position detection system
By merely setting the home position once, home position return need not
be done at each power on.
Section 5.7
Gain changing function
You can switch between gains during rotation and gains during stop or use
an external signal to change gains during operation.
Section 10.6
Advanced vibration suppression
control
This function suppresses vibration at the arm end or residual vibration. Section 10.4
Adaptive filter
Servo amplifier detects mechanical resonance and sets filter characteristics
automatically to suppress mechanical vibration.
Section 10.2
Low-pass filter
Suppresses high-frequency resonance which occurs as servo system
response is increased.
Section 10.5
Machine analyzer function
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.
Machine simulation
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.
Gain search 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.
Slight vibration suppression control Suppresses vibration of 1 pulse produced at a servo motor stop.
Parameters No.
