15. MR-E- AG-QW003 SERVO AMPLIFIER COMPATIBLE WITH ANALOG INPUT
15.5.3 Diagnostic mode
Name Display Description
Not ready.
Indicates that the servo amplifier is being initialized or an alarm has
occurred.
Sequence
Ready.
Indicates that the servo was switched on after completion of
initialization and the servo amplifier is ready to operate.
External I/O signal display
Refer to section 15.5.4.
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.
Output (DO) signal forced
output
The digital output signal can be forced on/off. For more information,
refer to section 6.7.
Jog feed
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".
Motor-less
operation
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.
Test
operation
mode
Machine
analyzer
operation
Merely connecting the servo amplifier allows the resonance point of the
mechanical system to be measured.
The MR Configurator (servo configuration software) is required for
machine analyzer operation.
Gain search cannot be used.
Software version low
Indicates the version of the software.
Software version high
Indicates the system number of the software.
Automatic VC offset
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.
