Mitsubishi Electronics MR-J2S- A instruction manual Diagnostic mode

6. DISPLAY AND OPERATION

6.3 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.
	Refer to section 6.6.	Indicates the ON-OFF states of the external I/O signals.
		The upper segments correspond to the input signals and the
External I/O signal		lower segments to the output signals.
display		Lit: ON
		Extinguished: OFF
		The I/O signals can be changed using parameters No. 43 to 49.
Output signal forced		The digital output signal can be forced on/off. For more
output		information, refer to section 6.7.
		Jog operation can be performed when there is no command from
Jog feed		the external command device.
		For details, refer to section 6.8.2.
		The servo configuration software (MRZJW3-SETUP111E) is
Positioning		required for positioning operation. This operation cannot be
		performed from the operation section of the servo amplifier.
operation
		Positioning operation can be performed once when there is no
Test
		command from the external command device.
operation
		Without connection of the servo motor, the servo amplifier
mode
		provides output signals and displays the status as if the servo
Motorless
		motor is running actually in response to the external input
operation
		signal.
		For details, refer to section 6.8.4.
Machine		Merely connecting the servo amplifier allows the resonance point
		of the mechanical system to be measured.
analyzer
		The servo configuration software (MRZJW3-SETUP111E or later)
operation
		is required for machine analyzer operation.
Software version Low		Indicates the version of the software.
Software version High		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
Automatic VC offset		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.
