Name Display Description
Not ready.
Indicates that the servo amplifier is being initialized or an alarm
has
Ready.
Indicates that the servo was switched on after completion of
initialization and the servo amplifier is ready to operate.
The servo motor can be jogged without pulse train input. During jog
feed, the servo amplifier acts as speed control servo.
The status display values of the droop pulses, cumulative command
pulses and command pulse frequency do not change.
For details, refer to (3) in this section.
The digital output signal can be forced on/off. For more information,
refer to (2) in this section.
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. Press once, set the first digit numerical value to 1
using the button or , and press again to make the
automatic VC offset function valid. When this function is
executed, the automatically offset value is set to parameter No.
29.
If the input voltage of VC or VLA is ±0.4V or higher, this function
cannot be used.
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.

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. This function can be used to make a sequence check on
the host positioning unit, etc.
For more information, refer to 2), (3) in this section.
