Description
Not ready.
Indicates that the servo amplifier is being initialized or an alarm
has occurred.
Ready.
Indicates that the servo was switched on after completion of
initialization and the servo amplifier is ready to operate.
Indicates the ON-OFF states of the external I/O signals.
The upper segments correspond to the input signals and the
lower segments to the output signals.
Lit: ON
Extinguished: OFF
The I/O signals can be changed using parameters No. 43 to 49.
The digital output signal can be forced on/off. For more
information, refer to section 6.7.
Jog operation can be performed when there is no command from
the external command device.
For details, refer to section 6.8.2.
Screen for manufacturer setting. When this screen is being
displayed, do not press any other buttons than "UP" and
"DOWN".
Without connection of the servo motor, the servo amplifier
provides output signals and displays the status as if the servo
motor is running actually in response to the external input
signal.
For details, refer to section 6.8.4.
Merely connecting the servo amplifier allows the resonance point
of the mechanical system to be measured.
The servo configuration software (MRZJW3-SETUP154E or later)
is required for machine analyzer operation.
Gain search cannot be used.
Indicates the version of the software.
Indicates the system number of the software.
If offset voltages in the analog circuits inside and outside the
servo amplifier cause the servo motor to rotate slowly at the
analog speed command (VC) or analog speed limit (VLA) of 0V,
this function automatically makes zero-adjustment of offset
voltages.
When using this function, make it valid in the following
procedure. Making it valid causes the parameter No. 29 value to
be the automatically adjusted offset voltage.
1) Press "SET" once.
2) Set the number in the first digit to 1 with "UP"/"DOWN".
3) Press "SET".
You cannot use this function if the input voltage of VC or VLA
is 0.4V or more.
