Monitor signal (analog)
On MR Configurator2, the status of the monitor signal (analog) can be obtained by using the "Display All" function and the
graph function.
Refer to the list in this section for the signals which can be obtained with the "Display All" function and the graph function.

5.1 Explanation of monitor signals
Description
The feedback pulses from the servo motor encoder are counted and displayed.
The displayed value is limited within the range of "-999999999 to 999999999". When the
value exceeds the upper or lower limit, it changes to "0".
The value is negative in reverse rotation.
In the fully closed loop control mode, the value is in load-side encoder units with the gear
taken into consideration.
The fully closed loop control mode can be used for servo amplifiers with firmware version
C4 or later.
The servo motor speed is displayed.
The number of droop pulses in the deviation counter is displayed. The value is negative in
reverse rotation. The number of pulses is displayed in the units of encoder pulses.
Position command input pulses are counted and displayed.
The displayed value is limited within the range of "-999999999 to 999999999". When the
value exceeds the upper or lower limit, it changes to "0".
The value is negative under the reverse command.
When other than "3" (pulse) is set in [Pr. PT01.2 Unit for position data], "0" is displayed.
The frequency of the position command input pulses is displayed.
When other than "3" (pulse) is set in [Pr. PT01.2 Unit for position data], "0" is displayed.
The command pulse frequency is converted and displayed in the servo motor speed unit.
The ratio of regenerative power to permissible regenerative power is displayed as a
percentage.
The continuous effective load current is displayed. The effective load ratio in relation to
the rated current (= 100 %) is displayed.
The rated torque is displayed as 100 %. The maximum value of the torque generated in
the past 15 seconds is displayed.
The instantaneous torque is displayed.
The rated torque is displayed as 100 %. The value of the generated torque is displayed in
real time.
The position within one-revolution is displayed in the encoder pulse unit.
In the fully closed loop control mode, the position within one-revolution is displayed in the
servo motor encoder unit.
The fully closed loop control mode can be used for servo amplifiers with firmware version
C4 or later.
For the linear servo motor control mode, the value of manufacturer setting is displayed.
The linear servo motor control mode is available on servo amplifiers with firmware version
A8 or later.
The travel distance from the home position is displayed as a multi-revolution counter
value of the absolution position encoder in the absolution position detection system.
For the fully closed loop control mode, the ABS counter is displayed in the servo motor
encoder unit.
The fully closed loop control mode can be used for servo amplifiers with firmware version
C4 or later.
For the linear servo motor control mode, the value of manufacturer setting is displayed.
The linear servo motor control mode is available on servo amplifiers with firmware version
A8 or later.
For details, refer to "Checking the detected absolute position data" in the following
manuals.
MR-JET User's Manual (Hardware)
The estimated ratio of the load inertia moment to the servo motor inertia moment is
displayed.
The bus voltage of the converter part of the servo amplifier (between P+ and N-) is
displayed.
The feedback pulses from the load-side encoder are counted and displayed.
The displayed value is limited within the range of "-999999999 to 999999999". When the
value exceeds the upper or lower limit, it changes to "0".
The value is negative in reverse rotation.
