Load-side encoder
information 1
The position within one-revolution of the load-side encoder is displayed.
When an incremental type linear encoder is used for the load-side
encoder, the Z-phase counter of the load-side encoder is displayed in
units of encoder pulses.
When an absolute position type linear encoder is used for the load-side
encoder, the encoder absolute position is displayed.
Load-side encoder
information 2
When an incremental or absolute position type linear encoder is used as
the load-side encoder, "0" is displayed. When a rotary encoder is used as
the load-side encoder, the multi-revolution counter value of the encoder is
displayed.
Temperature of servo motor
thermistor
The thermistor temperature is displayed for the servo motor with a
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
pulses (BeforeGear)
The feedback pulses from the servo motor encoder are counted and
displayed. (Servo motor encoder unit)
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
deviation
The position deviation between the servo motor-side and load-side is
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
deviation
The speed deviation between the servo motor-side and load-side is
displayed.
This function can be used for fully closed loop control.
Internal temperature of
encoder
The internal temperature detected by the encoder is displayed.
Settling time
The period of time (settling time) from the completion of the command to
INP (In-position) on is displayed.
Oscillation detection
frequency
The frequency at the time of oscillation detection is displayed.
Number of tough drive
operations
The number of times the tough drive function has activated is displayed.
Unit power consumption
The unit power consumption is displayed. The positive value is displayed
in power running. The negative value is displayed in regeneration.
Unit total power consumption
The unit total power consumption is displayed.
Excessive error alarm
margin
The margin for the excessive error alarm trigger level is displayed in the
encoder pulse unit. The excessive error alarm is triggered when the
margin is 0 pulse.
Overload alarm margin
The margins for the alarm levels of [AL. 050 Overload 1] and [AL. 051
Overload 2] are displayed as a percentage.
Overshoot amount
The overshoot amount during position mode is displayed in units of
encoder pulses.
Disturbance torque
The difference between the necessary torque and the actually required
torque (torque current value) to drive the servo motor is displayed as the
torque equivalent to disturbance.
Current command
This indicates the current command applied to the servo motor.
Speed command
This indicates the speed command being applied to the servo motor.
In the position mode, the speed command calculated from the position
command and command filter is displayed.
Command speed output 2
The command speed to be used for speed control is displayed as the
command output of the analog monitor.
Torque command
The target torque value of the torque command in the torque mode is
displayed. "0" is displayed in the position mode and velocity mode.
Speed limit value
The speed limit value in the torque mode is displayed.
"0" is displayed in the position mode and velocity mode.
U-phase current feedback
This indicates the U-phase current value applied to the servo motor in
internal units.
