Name Description
Load to motor inertia ratio The estimated ratio of the load inertia moment to the servo motor inertia
moment is displayed.
Bus voltage The bus voltage of the converter part of the servo amplifier (between P+
and N-) is displayed.
Load-side encoder The feedback pulses from the load-side encoder are counted and
cumulative feedback pulses displayed.
*2
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.
Load-side encoder droop Droop pulses of the deviation counter between a load-side position and a
*2
pulses command are displayed.
Load-side encoder The following values are displayed for each encoder connected to the
information 1 load-side.
For a rotary servo motor, the position within one-revolution is displayed.
For an absolute position linear encoder, absolute position data is
displayed.
For an incremental linear encoder, the Z-phase counter (distance from the
linear encoder home position (reference mark)) (32-bit data) is displayed
after the Z-phase is passed. The value before the Z-phase is passed is
undefined.
For an A/B/Z-phase differential output linear encoder, the Z-phase counter
(distance from the linear encoder home position (Z-phase)) (16-bit data) is
displayed after the Z-phase is passed. Before the Z-phase is passed, a
free-run counter is displayed with the position where the power is turned
on set as "0".
For an A/B/Z-phase differential output rotary encoder, the position within
one-revolution is displayed.
Load-side encoder The following values are displayed for each encoder connected to the
information 2 load-side.
For a rotary servo motor, a multi-revolution ABS counter, that holds the
counter value even when the power is cycled, is displayed. For the HK-
MT_VW, however, a multi-revolution counter, that returns to "0" when the
power is cycled, is displayed.
For an absolute position linear encoder, "0" is displayed.
For an incremental linear encoder, "0" is displayed.
For an A/B/Z-phase differential output linear encoder, "0" is displayed.
For an A/B/Z-phase differential output rotary encoder, "0" is displayed.
Temperature of servo motor The thermistor temperature is displayed for the servo motor with a
thermistor thermistor.
For the servo motors without a thermistor, "9999" is displayed.
For the servo motor with a thermistor, refer to the user's manual for the
servo motor being used.
Motor side cumulative F/B The feedback pulses from the servo motor encoder are counted and
pulses (BeforeGear) displayed.
(Servo motor encoder unit)
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.
Electrical angle The servo motor electrical angle is displayed.
For the linear servo motor control mode, the value of manufacturer setting
is displayed.
Motor/load side position The position deviation between the servo motor-side and load-side is
*2
deviation displayed.
This function can be used for fully closed loop control.
The number of pulses is displayed in the load-side encoder unit.
Motor/load side speed The speed deviation between the servo motor-side and load-side is
*2
deviation displayed.
This function can be used for fully closed loop control.
Internal temperature of The internal temperature detected by the encoder is displayed.
encoder For the linear servo motor, "9999" is displayed.
Settling time The period of time (settling time) from the completion of the command to
INP (In-position) on is displayed.
